Friendly Reader,

I have taught in the first part of this Book, by what way the Vegetables, as Wine, and Ale, are to be concentrated, whereby they may yield more profit than hitherto they have done, and also, how Wood is to be reduced into Salt-petre. In this present Second part, shall be taught, how the Salt-petre is to be used, and how, by it Minerals may be Concentrated, and wrought into Metalick Bodies. And as to this Concentration, thus stands the case; that is to say, forasmuch as a good part of Minerals are of very little use, and lie neglected as things of no worth, and prove not profitable to any one, (whereas if there were Men that understood but the Art of it, there might redound a great benefit to the Lands where they are). It hath seemed to me worth while to declare it to my Country, nor doubt I but that there will arise some diligent ingenuities, who will lay the thing to heart, and take care thereabouts, and will even set their hands to the work it self, and thence get much profit; which to me would be very pleasing and acceptable. Therefore (in the Name of God) will I set about the manifestation of the Gifts of God (which lie every where unknown, and wholly disesteemed, and which yield no Man any fruit) and lay them open before the Eyes of the whole World, that so they may be better known hereafter, and be of more benefit to the Country. And I beseech the most Wealthy, and the most Ancient Housholder, our most merciful Father, to bestow a Blessing, and good success on this my endeavour, that it may tend to the Honour of his most Holy Name, and the health of all our Souls. Amen.

Of the difference of Minerals, and what is understood by the Name of Minerals.

As concerning the word Mineral, why all Fossile and Metalick Mines are so called afore they have been wrought upon, and brought by the fire into Malleable Metals, I judge it but of small moment to make any tedious Comment thereupon; besides, others have long ago thoroughly treated of that, and yet it makes but little to the thing it self. But my purpose is (at present) to teach, what means such little esteemed Minerals may be made useful, and profitable by; but afore I begin this work, I will recite, and shew the many sorts of Minerals that there be; then next that, I will shew how, by the benefit of fire, and the hands of the Artificer, they may be converted into better bodies, and become useful, and profitable for Mankind.

Under the Name of Minerals are comprehended, or reckoned these following, viz. Antimony, Auripigment, White, Yellow, and Red Arsenick, Cobolt, Lapis Calaminaris, Zink, Bismute, or the Silvery Marchasite, likewise the Golden Marchasite, Pyrites, or Copperas stones, Vitriol of various kinds; as also, its kindred, may be added to the number of Minerals. And albeit, that some do also referr Alume, Salt-petre, Sal Armoniack, Sal Gem, and others of that kind to the rank of Minerals, yet cannot I acknowledge them for such, or reckon them up amongst the number of the above mentioned, seeing there is nothing Metalline to be found in them: Such only therefore do I call Minerals, that have in them a Metalline nature, and which do admit of being joined with other Metals, and of being molten together with them in the fire, and out of which the known Malleable Metals, may be extracted. These are they which I intend to treat of, and will see, what good is thencefrom extractable.

And first of all we’ll speak of Antimony.

Antimony is the noblest Mineral of all, not only because it doth for the most part contain Gold in it, but upon this account too, because more eminent Medicines may be thencefrom prepared for the use of Mankind. In the Mine-pits it has its peculiar Veins; that which is found in Transilvania, hath some little bigger portion of Gold in it, and is accompted of as the best in all Europe, next that is the Hungarian ♁, which likewise doth sometimes contain no contemptible portion of Gold; next is the Fechtenbergick, which is found at a small Town call’d, in the German Tongue, Gold-Gronack; the Polonian sort, and that which is found in most places of Germany, contains but little Gold, or none at all; but there is some which has much Silver in it, and (for the most part) is neither wont to be used, nor desired, or sought for, save by the Letter Founders, and these use it to make their Matters flow. Also many do use it (viz. ♁) in Medicine, and do much good therewith, but it hath certain Enemies who are none of the wisest, and so is hated, and rejected. But yet there lies in it more hidden good, than all its Enemies are able to conceive of, witness my Panacea, which is mentioned in the second part of my Pharmacopœia Spagyrica.

And Basil Valentine, certainly an excellent Philosopher, writ the Triumphant Chariot in its Honour, which is an exquisite Book and profitable to read.

But as concerning the way of making a Regulus out of Antimony, and as to the uses it serves for, that I have described in the fourth part of my Furnaces. Moreover, as to the manner of depurating Gold thereby, and cleansing it from all Heterogeneous mixtures, and as to the graduating of silver, thereby, that it may become Golden, all this have I spoken of in the Explication of my Miraculum Mundi; and as to what other effects may profitably be done, therewith in Metalick Operations, shall be shown, partly in this Treatise, partly in the third and fourth ensuing parts. As concerning the way of separating it in quantity out of the Ore, per descensum, is to be seen in George Agricola’s Book, that he wrote of the Metalick Art, and in others; nor indeed belongs it to this place to speak thereof.

Of Arsenick.

Arsenick likewise is a good Fossile, or profitable Mineral, and is put to many Uses. It also hath its singular, or distinct Veins in the Earth, whence it is taken; it is forced out of the Ore by Ascension, and Descension, and is purified for use: It is found white, yellow, and red. Also some silvery Minerals or Ores do in their solution, or melting; yield much Arsenick, which the Melters of the Ores do catch in Chimneys or Funnels made for that purpose, and keep it for use; concerning which, you may read in George Agricola’s Writings. So likewise, Cobolt yields Arsenick, and so do some Golden Minerals, or Ore; that which is separated from a Minera of Gold, per descensum, is very red, and auriferous; and this, those that deal with Metals, have experience of; which, if they separate not from the Gold Ore afore they melt it, it carrys away a great part of the Gold, and hides it in its Belly in the melting, so that they would not have so much Gold as there is in the Ore. For indeed, such a kind of Arsenick, is an unripe Gold, as shall be hereafter proved: So then, there lies more hidden in that Contemptible, and Venomous Arsenick, than any one will easily perswade himself to believe. There are also Medicines prepared out of it, but such, as serve only to be externally applied, in inveterate, and virulent Evils, as the Cancer, and Fistula. It is also used in Colouring and Dying Cloaths, concerning which, you may peruse my other Writings.

Of Auripigment.

This Mineral is in a manner of the same Essence that Arsenick is of; but this does not come forth of Minera’s, or Metalline Ores, but hath peculiar Veins of its own, in which it is generated; it is an unripe Mineral, and doth for the most part also contain Gold. It is exceedingly Poisonous and Volatile, and therefore it is but little used, save only by Painters. It can be fixed by Nitre, and it makes Copper white, and brittle, as Arsenick doth: And it suffers it self to be sublimed out of its yellowness, into Transparent Rubies, which are used for Ornaments sake.

Of Cobolt.

Amongst all the Minerals that are to be found Cobolt is the most poisonous; it’s an unripe silver, and it ofttimes yields in melting good silver, yet one sort more than other; some also there is which hath not any Silver at all, and is used about the sky-colour’d Smalt, to help make it, with an addition of Fusile Sand, and Potters Ashes. But when they meet with that which has Silver in it, they separate it thencefrom by Fusion; besides, it may be so fixt by the help of Salt-petre as to yield permanent Silver, as shall anon be spoken of.

Of the Silvery Marchasite.

The silver Marchasite, or Wismuth, is a known Mineral; it’s every where found to and again in the silver Mine-pits, as well as Cobolt is, but yet it is much more fixt than Cobolt; neither is it of so poisonous a Nature. It is gotten out of its Ore, or Minera, most easily by a small flame of wood fire, and is used by the Pewterers to make their Pewter hard, sounding, and fluxile. Likewise, out of its scoria or drossy parts, is the blue Smalt also prepared, which the Potters use to glaze their Pots, and the Glass-men to make sky-colour’d Glasses. It doth very frequently abound with much silver, and ’tis rare to find any that is wholly void of silver: And if it holds so much silver, as is of more value than the Marchasite can be sold for (as ’tis barely Bismute) they separate it, if not, they leave it in it. For if an hundred weight doth not contain 20 or 30 Lots, or half Ounces they do not separate it, because the Marchasite will yield so much. But now, the Silver may be gotten out of the Marchasite, by Salt-petre, so as that the remaining Marchasite shall lose nothing of its goodness nor be at all spoiled, as I have shewed in the Explication of my Miraculum Mundi.

Of the Golden Marchasite.

The name of Marchasite is proper to every unripe Metallick matter (and is) of as many sorts as there are Metals; hereupon the matter which has Gold in it, is called the Golden Marchasite; that which has Copper, the Coppery; that which has Iron, the Irony, and so that which abounds with Sulphur, is called the Sulphureous Marchasite. But now there is Sulphur in all the Marchasites, and sometimes Arsenick too, but (the Golden ones) have more of Gold than the other Marchasites have; Besides, out of all kinds of Marchasites proceeds (for the most part) a Vitriol, which shews the nature of that Metal, which the Marchasite contains; one while Copper, sometimes Iron; ’tis rare to find a Marchasite that hath no Metal at all in it; if it hath nothing of Gold, Silver, or Copper, yet has it Iron, and gives out of it self a Vitriol useful for Dyers, and which such as prepare Aqua-fortis cannot be without.

Of Zink.

Zink is a Volatile Mineral, or a half ripe Metal when it is drawn out of its Ore. It is much clearer and brighter than Tin, yet not so malleable and fluxile as Tin is, and it is usually put to Tin to make it brighter and harder. We have it not much growing in Germany, but great quantity of it is every year brought us by the Merchants out of the East-Indies. The way how to prepare it for Medicinal uses, have I described in the first part of the Philosophical Furnaces. It is a golden but an unripe Mineral, it gives Red Copper a Yellow Colour and turns it into Brass, as Lapis Calaminaris doth; and indeed that same Stone is nothing else but unmeltable Zink, and this Zink may properly be called a fusile Lapis Calaminaris; for as much as both of them partake of one nature. But with Zink, there is most an end conjoined Lead too, and then it is not fit to make Brass of, unless the Lead be first taken thereoutof; so it is at Goslaria, where together with the Minera or Ore of Zink is Lead also digg’d out mixt amongst it, and is called a Lead Ore, though there be contained in that Ore, four times more of Zink than there is of Lead, and yet they burn up the Zink for to have the Lead, which Lead hath some Silver in it. In the melting it flies away in fume, and it is a volatile and combustible Mineral, and sublimes it self up into the holes of the Furnace, whereupon the Melters or Founders are constrained to knock it off frequently, least it should too much lessen the Furnace; this matter they knock off, they call Calmei (which is Lapis Calaminaris) and which turns red Copper into Brass, with encrease (of its weight); and so verily by means of the not-knowing or being skill’d in this Ore, a great quantity is yearly burnt up and lost. Sometimes the founders do gather somewhat of the Zink, which is most excellently excellent; but that Ore might be melted with far greater profit, if they did not so burn up the Zink, and force it into fume, but seeing men are hardly drawn back from an old custom, it must be born with.

But yet (I say again) if that Ore were handled in a due manner, there would redound far greater profit thencefrom than now doth. Such a kind of Mineral as this is doth Westphalia also yield, which the founders there accompt for a Leaden Ore, because it has some load mixed with it, but when it comes to be freed or molten it goes (all) away in fume, and therefore they say, it is also a Calmei or Calaminaris Ore, and so it lies unused.

Of Calmei or Lapis Calaminaris.

Calmei Ore is digged out in many places in Germany, but there is none of such note as that which is found at Aquisgrane, for that is wholly void of all kind of Leadyness, and much different from that of Goslaria, or Westphalia; and therefore it is also very fit to make Brass of, which is there made in plenty, and farther, this has Gold in it, though not so much as to quit the Costs of separating it. But there is no Mineral richer with Gold than this, and could it but be ripened (and I doubt not at all of the possibility of so doing) a good deal of Gold might be drawn out from thence.

As concerning what else may be performed with that Mineral, I have formerly told you in my First and Second Part of Furnaces, nor is it needful to treat of the same thing more at large in this place.

Of Common Sulphur.

Sulphur or Brimstone is the most known, most used, and most combustible Mineral of all. As touching its uses in Medicine, and in Alchimy, about the separation of Metals; may you find something mentioned by my self, in the writings I formerly published, and in the writings of others too.

But at present we will only mind you of this, viz. That it is the very Foundation and Root of all the Metals; for tis rare to find any mine wherein Sulphur does not shew it self. Very many places in the World, is Sulphur both made and digged out of the Earth, in very great quantity, & that chiefly in Island, and in Italy, nigh to those always burning Mountains, Heckla and Vesuvius; it is also drawn out of Marchasites per Descensum in many places of Germany, so that enough of it may every where be had for a little money.

These are the chiefest Minerals that I ever knew of, and these are they which are commonly sought after, and applied to use. But now, besides these, there are so many various kinds of Fossiles and Minerals to be met withal, that one cannot reckon them all up, or give them peculiar Names. One contains Sulphur, and Arsenick, another, Cobolt and Sulphur; another Antimony, and Arsenick, and of that kind are there very many more. But yet those that we have reckoned up, are the most known, and most in use, and therefore shall at present be sufficient for us to speak of.

Having now taught what Minerals are, and which of them are most known & used; I will now teach, in the next place, by what means they may (by the help of Salt-petre, & of other Subjects) be fixed, concentrated, imbodied, or brought into Metals, so as to be rendred profitable for the use of Mankind, and which otherwise lie every where to and again neglected and, are wont to be of no esteem.

And as to the Concentration of Minerals, thus stands the Case with them; they are either to be fixed & subdued, as ’twere by the help of Salt-petre, that so they may not so suddenly fly away in fume in the fire, and be burnt up, but may abide the fire and suffer themselves to be molten; or they are to be reduced into bodies by the help of Metals, that so they may come in use, and that by augmenting the Metals, as Lapis Calaminaris does, or they are to be purifyed, separated, and made better, as shall be mentioned of Sulphur, Antimony, and the others, that so those kind of Minerals of which there lies to and again, at present, great quantities, wholly neglected, and profitable to no body, may hereafter be of use and benefit.

And first of all, as to the fixation of the Minerals, the way of proceeding is thus, viz. The Mineral is to be powdered, and to be mixt with equal weight of burning Salt-petre, and so to be fired, that the combustible and volatile part of the Sulphur may be forc’d away, and the Mineral may afterwards brook the fire the better, and be molten and forced downwards (per descensum); which operation I have treated of in the explication of my Miraculum Mundi, and therefore think it needless to repeat the same thing again here. By this mean therefore may Arsenick, Auripigment, Cobolt, Zink, Bismute, and other Volatile Minerals be in some sort fixt by the inflaming and burning up with Salt-petre, so as afterwards to endure the fire, and to yield forth the good they have in them. There’s also another way of imbodying Volatile Minerals, viz. by the benefit of Metals; if the Metals and Minerals are joined together in a due measure, and be likewise united together by the virtue of a Cementing fire; then doth the volatile Mineral penetrate it self into the Metal, and becomes Metalline, and doth also encrease the Metal, as is evident in Calmei or Lapis Calaminaris, which being joined with red Copper and cemented, enters into it, augments and encreaseth it, and turneth it into Brass; whereas there cannot be any Metal educed out of the Calmei by the usual way of melting. In like manner may all Arsenical minerals be (by cementation) introduced into Copper, & made corporeal; and these do not colour the Copper yellow as Calmei doth, but make it white, nor is the Copper rendred maleable thereby but britle; but yet ’tis not without profit; for if that white Copper be handled after a convenient manner of taming or over-mastering it, then the Gold and Silver that was in the Arsenick, betakes its self into Regulus’s, which are to be depurated in a Test or Cupel, or else by the help of Salt-petre; but there cannot any metalline body be made out of Arsenick, Auripigment, or Cobolt, by bare melting. The way of proceeding with it is thus; The Copper is to be cut into small bits, and to be moistned over with Linseed Oil, and the Arsenick, Auripigment, Cobolt or any other Realgar is to be powdered and strewed thereupon, and so a bed of Copper, and a bed of Arsenick to be put one a top of another in a melting Pot; then the Pot is to be well covered and fenced with Lute, and placed in a circulatory fire, and the fire is to be put nearer and nearer to it, until the Pot is through red hot, then let it cool, and you shall find that the Arsenick hath gotten ingress into the Copper, and makes it black and brittle. The Copper thus burnt, may be reduced into powder, and burnt with good Salt-petre, whereby the Volatile Gold and Silver which was contained in the Arsenick, is made corporeal, and abides as constant upon the Test as other fixt Metals do; so that by this means permanent and good Gold and Silver may be gotten out of every sort of Arsenick, Auripigment, Cobolt, and the other volatile, venomous and base minerals.

NB. This kind of operation is very dangerous to those that are unskilful, and who being unversed in the Chymick Art, have not learned to take heed to themselves. And therefore it behoves every one to beware of doing ought rashly or heedlesly. He that knows not how to carry himself (or his business) warily, let him forbear to meddle at all with this labour or process: But as for one who is better versed, and pretty well experienc’d, he may set about this work safely and will gain by it: Because there is oftentimes found Arsenick and Auripigment that hath in it much hidden volatile Gold and Silver, and which cannot be retained in the common way of melting by Fire, but will totally fly away: But now if it be imprinted in the Copper by Cementation, and fixt in the same by Salt-petre, and then precipitated by means of Lead or Iron into Regulus’s, it will render all that fixt which afore was unfixt and flying. But as concerning such a Cementation and Fixation to be done by Nitre, will be manifested by the following process.

NB. But you are carefully to observe, that one mineral must help another in the separation of their Gold and Silver (if you would undertake this Labour for profit): For so each will produce what it has in more abundance, and thou wilt have a greater reward for thy pains and costs. For example, I prove and try Auripigment or Arsenick, and find that it is auriferous, and I have a mind to perfect it and turn it unto my use; hereupon do I look for such Copper as is likewise auriferous, (and indeed there’s plenty enough of such every where): Into this Copper do I introduce my auriferous Arsenick by Cementation, and that I may not need to cupellate (or blow off) the same upon a Test (for the very Labour of so doing will cost more than the gains will be of that separation) I do precipitate the Gold that is therein into a Regulus, which Regulus being purified, I obtain the Gold that was contained in that Arsenick and Copper, neither is there any need of cupellating all the Copper. But that the precipitation of the Regulus may be the more commodiously done, I proceed on this wise. I find out some Antimony of a good sort, and which is of a Golden nature; likewise such Iron as hath Gold in it, both which, viz. the Iron and the Antimony, may easily be gotten, and then I set on the separation which I thus institute.

First of all I implant the auriferous Arsenick into the auriferous Copper (if such may be had) then reduce I these into powder, and fire them with an equal admixt weight of burning Salt-petre; by this means the Arsenick is made a little more fixt, and suffers it self to be the better dealt withal in the fire, but if you are well skilled in this kind of labour you may spare your Salt-petre and may melt down your Copper (burnt with the Arsenick and powdered) with an equal weight of Antimony. And if of its own accord it lets fall a Regulus out of it self, then there needs no precipitation, the Regulus may be laid by, and that which remains may be likewise precipitated into a Regulus with common Iron; and this (last Regulus) is also of use, as shall hereafter follow: But if not (that no Regulus falls) then that Mass may again be put into a Crucible, be molten, and a little Iron filings be cast in to make it settle; the which must be stirr’d about with a red hot Iron rod, and when it’s well molten, ’tis to be poured out into an Iron Cone; which being cool, the Regulus may be knockt off, in which Regulus will you have the Gold that was in the Arsenick, Copper, Antimony and Iron. This Regulus must be cupellated either by Salt-petre in a Crucible, or with Lead upon a Test; which done, you will have the Gold that lay hid, and shut up in the afore-mentioned Minerals.

But now, if one hath a mind to make that separation yet more compendious, and to have greater benefit thereby, he may add to that Copper burnt by the Arsenick, some Silver burnt with Brimstone, and so melt it with the Antimony, and by the means of Mars precipitate them into a Regulus, then the Silver will so much the better draw to it self the Gold out of the Arsenick and Antimony, and yield (in the separation) greater benefit.

NB. If so be a man be not skilful in this operation, let him forbear his Silver a little, and add some Silver to the Regulus by melting them, and then afterwards purifie the Regulus by Salt-petre; for so the Gold that is in the Regulus associates its self to the adjoined Silver, and inricheth it with no little increase, viz. according as the Minerals have had more or less Silver, in the making their separation.

And this is such a work as seems sufficiently able commodiously to sustain life; but it requires an experienced Artist, not a giddy headed fellow. Neither have I written this process for those who are not as yet well versed in Pyrotechny, but for such who are well skill’d and dexterous; and although this kind of operation needs no great store of Art, yet notwithstanding, every one will not rightly perfect it, and therefore do I warn such as are not well skill’d in Pyrotechny to desist from this labour, and betake themselves to some other, and set themselves about doing such things in which haply they are better skill’d, and not to lay the blame on me, when they are frustrated of their expectation, as if I had not dealt faithfully and sincerely in my writing, but let them rather impute it to their own preposterous rashness and unskilfulness; and what loss soever they bring upon themselves, let them impute it only to their own (misconceptions).

To deal plainly with you, that labour is conjoyned with some difficulty; but yet if any one be diligent and well exercised in the Pyrotechnical Art, the operation will succeed in such an ones hands very pleasantly; nor will he want a worthy profit, especially if he takes such Minerals as are richest, and use them about this separation. But some perhaps will say, Whence shall I have those so good Minerals? Who demonstrates to me, which are auriferous, and which are not auriferous, which are good, and which are to be rejected, that so least being deluded in this, I should lose all my labour? I would have such a one know, that if he has not gotten so much skill and experience as to prove a Mineral, whether it be auriferous, or not, he is not at all fit to take upon him this Labour of separation, and he were far better advised, if he wholly abstained from setting about it. But yet that I may not omit ought which may seem to be desired from me, I will over and above add here in this place, what way Minerals may be proved by, whether they be auriferous or not, and ’tis on this wise to be done; all Realgars, as Arsenick, Auripigment, Cobolt, and others of that kind, are first of all to be implanted into Copper by cementation, then are they to be molten, or throughly purged and subdued with Lead (like as you do with a crude Mineral); after this, there comes out a certain little silvery Pellet, and this you are to prove as you would for Gold. Now according to the moreness or lessness of the same, so is the business to be ordered, and compute to be made, whether or no the said Mineral is worth the pains of separation as aforesaid. Likewise the Copper it self may be cupellated with Lead alone, and then the remaining silver Pellet be proved for the Gold, with Aqua-Fortis; but as for the Antimony, and Iron, they may be well melted jointly together in a Test under a Cover or Muffel, or in a clean Crucible in a Wind Furnace, with this observation, that there be used twice as much Antimony as Iron, and so a Regulus will settle, which is to be purged or tried with Lead in a Test, and kept flowing till all the fugacious parts are evaporated, which done, there is found a silver Pellet, which is to be proved with Aqua-fortis, how much Gold it has.

NB. This probation, or trial is to be accounted of as a certain and lawful trial, but such though as you may easily err in the doing of, and so may have nothing, though it had in it a good part of Gold; for the Antimony will not easily suffer it self to be vanquished, or go off, but it will break the Test, or Cupel, and the little Pellet which is the probatory Globulus betakes it self (by reason of the fierceness, or eating penetrativeness into the Test) so that the Proba or trial it self, may most easily become fallacious, and yield no certain discovery. Which to remedy, the business is to be thus managed, after that your two parts of Antimony shall have been well melted in the Crucible, with your one part of Iron, there must be put thereinto a little dried Salt-petre powder, and the Pot, or Crucible must again be covered over, and care taken to make them melt well together; then are they to be poured out into an Iron Cone first smeared over with Wax, and when ’tis cold, the Regulus is to be knockt off from the Scoria, to which must be added twice or thrice the weight thereof of Lead, and the Regulus of the Antimony doth in the melting-pot separate it self by Salt-petre from the Lead, and the Lead is to be afterwards cupellated, and so that goes all off, and the true weight is had. But albeit, that this description be clearly enough delivered, yet certain I am, that one in ten will not understand it aright, and therefore it is behoveful, more fully to inform, and clearly to shew the Reduction of that Regulus into scoria by Salt-petre. To make this trial or proof ’tis not needful to take a huge vast pot to fill with Iron, ’tis sufficient to take of Iron 100 l. of the smaller probatory weight, and 200 l. of Antimony, both which are to be molten together, and to be precipitated with a little Salt-petre, for so the Regulus doth the better separate it self from the scoria’s, the which is then to be washt and purified by Lead and Salt-petre. This Regulus that comes from the Antimony and Iron, put with three times its weight of Lead in a clean Crucible, and make them well to flow in a wind Furnace, but cover your pot close that no Coals fall in, and so hinder the work, then take off the cover and throw in a little powdered Salt-petre, and again cover the Crucible, and above all things have a care that there fall not in any Coals, and let them lie and operate a little upon each other, then the Salt-petre imbibes all the Antimony, Iron, and Lead, and thereby becomes hard. This being done, some more Salt-petre is to be again cast in, and you must make them flow together, and so all the whole parcel of Antimony, Iron, and Lead, betake themselves into the Salt-petre, and pass into scoria, but part of the Lead remains whole or free, and is not scorified, and therein will the Gold be, which the Antimony and Iron had immixed in them, which if it be blown off on a probatory Cupel, or Test, under a Muffel, there will then remain the true weight.

NB. But it is expedient, that there be a just proportion observed in this kind of Work, that you take not overmuch Salt-petre to this ablution, or converting it into scoria, and so bring all the Lead into scoria, but the business is so to be managed, that there be left remaining one third part at least, of those three parts of Lead you took, which is not reduced into scoria with the Antimony; then may it be poured out into a Cone, and when ’tis cool, the Regulus is to be knockt off from the scoria, and Cupellated.

NB. He that is minded to wash Metals after this manner by the help of Salt-petre, and to reduce them into scoria, must have an especial care that not a Coal falls into the Crucible, for they will much hurt, and will again precipitate them, which the Salt-petre hath already imbibed, and so render the operation invalid. Besides, it is worth the while to admonish, and tell you that all Arsenick, and Antimony is auriferous, but yet so, as that one sort is richer than another, and that abundance of Copper and Iron hath likewise in it Gold, which no body finds out, nor can it be separated by that old beaten way of Cupellating it with Lead. But some, or other might here say, Where shall I find Arsenick, Antimony, Copper, and Iron, which have Gold in them? Had they any thing of worth in them, others would doubtlesly have extracted it, and not have suffered it to come to my hands whole and sound? To satisfie such an one, I answer thus, tho’ those that work on the Metals, do for the most part know, that there is in Arsenick and Antimony, a Volatile Gold, yet know they not how to extract it thencefrom with profit, for the separating way they take would cost more than the Gold they should have would yield, because (according to their usual way and custom of working) all of it would vanish away with fume. And this is to be understood of Arsenick, Auripigment, Cobolt, and Antimony, all which may (by the way we have here mentioned) be tamed and introduced into Copper, and be made permanent and fixt.

But now, that there should sometimes be Gold implanted, naturally in Copper, and should there also be left remaining untoucht, is so done on this account, because there is not in it so much as to pay the Costs of the separating it by Lead (for verily the Cupellating it with Lead on a Test, requires great expences.) This is the reason why Gold lies immixed in the Copper oftentimes, and cannot be thence extracted with profit.

The same is to be understood of Iron, for a Vein of Iron doth oftentimes offer it self, which is very much impregnated with the more precious Metals, and yet no body either knows, or observes it. For the Ore of Iron is for the most part wont to be forced out by unskilful Men who have no care at all of the Gold, but only of such an Ore as contains a good portion of good and malleable Iron; and suppose they did certainly know, that there were in 100 l. of Iron, some Lots of Gold, by what means (I pray) would they extract it thencefrom? For Iron cannot be dealt withal by Cupellation on the Test, much less can it be separated (as Copper is) by the means of Lead; so that there’s no reason for any one to wonder that there are so few to be found, that promise themselves, or seek after much good out of Iron, seeing it is not so apt a Subject to be separated, and subdued as Copper is. But by the help of Arsenick, Auripigment, or Antimony, ’tis no difficult matter to tame, and bring it under, so as to make it yield forth what it has: And ’tis thus. This Iron, which is auriferous, may first be cemented with Arsenick, as we have afore taught of doing so with Copper, then is it to be precipitated into Regulus’s by means of Antimony, which Reguli being imbued, or mixed with Lead, and reduced by Salt-petre into scoria, and cupellated, the Gold doth at last offer it self (which was hidden in the Minerals, or Ores, and so despised) and that with no contemptible profit. But now if any hath a mind to have the business yet more perfect, he may instead of Lead, add some Gold, and then reduce the Regulus into scoria’s, by Salt-petre, and abstract it from the Gold; for so the Gold you put thereto doth the better hold that other Gold which it has attracted out of the Regulus, and there is made a much more plentiful encrease, than if the Regulus had been scorified upon Lead. Nor are the scoria to be thrown away, but they may be precipitated by throwing in live Coals, whereby the Salt-petre doth again let fall the Regulus which it hath swallowed up, and which Regulus you may separate from the dross when ’tis cold. This Regulus may be afterwards commodiously used in other Metalick Operations, that so it may yield anew out of it self the Gold; concerning which business there will a place fall in to speak of by and by. And besides, those drossy Offals (which for the gratest part are fixt Salt-petre) are also of good worth, which may be reserved for the subsequent Metallick Operation, which may be stiled a perpetual Metallick-working artifice; so that there is nothing at all wasted, but all things are of use. And this way of the separation of Metals is so very profitable, as that any one may get himself sufficient gain for to supply the necessities of Life. But if you have no fansie to meddle with Arsenick, or Auripigment and would willingly shun them by reason of their poisonous nature, they may even be omitted, and you may cement that auriferous Iron, with the Golden Marchasite, melt it with Antimony, and precipitate it into Regulus’s. For even by this means too, the Gold that was in the Marchasite, is brought in use, and yields an increase to that Gold which is extracted out of the Iron and Antimony. But if so be there be no Golden Marchasite to be gotten, that separation may be ordered, even with Iron and Antimony, and if the Iron be but auriferous, the Labour will not be without profit.

This kind of separation or eduction of Gold out of the volatile Minerals, and baser Metals will be an egregious aid or benefit to such as have learned rightly to operate in the Fire, and whom (otherwise) a grievous want of things and small estate afflicts; for there is enough of the aforesaid Minerals, every where obvious, but they cannot be well handled, or wrought upon by reason of their unfixedness and immaturity, and therefore do they lie neglected and as it were wholly useless, and are not made beneficial to any. I know that some do well understand the way of fixing Cobolt, and Bismuth by Salt-petre, and do thence get an abundance of Silver; and likewise there are some that know how to tame and subdue Arsenical Realgars by the help of Salt-petre, so that they suffer themselves to be molten, and yield forth their hidden Gold and Silver. But he that shall so manage the business as to adjoin thereto the auriferous imperfect Metals, such an one will make a more successful work thereof; especially if he gets himself some auriferous Iron, the which he may get for a small matter: And besides, if he makes his Salt-petre himself, then all that whole operation of fixing or separating the volatile Minerals would be done with very little costs, and yield much gain.

NB. But now if any one would yet get more profit by this separatory operation, then he must contrive the doing it not in Crucibles or Pots, but in hearths (or furnaces) where a great heap of the volatile Mineral may by fixing Nitre melt together, and be precipitated into Regulus: then the Regulus may be separated from the Scoria, and be depurated by Nitre in other Furnaces, and be fitted for use; and so by this means may there be so much gain gotten, the like whereof, the great heaps of Ores which Men are necessitated to dig out of the bowels of the Earth with so much expence and charges, will scarce afford.

Likewise all Minerals may by the help of Salt-petre be fixed by the moist way, so as to yield permanent Gold and Silver; whereby (without doubt) full as much, if not more, is obtained, as is by the dry way. The way of operating is this. Dissolve a volatile Mineral, be it Cobolt, or Zink, Wismuth, Calmei, Arsenick, Auripigment, or any other the like mineral, in a strong Aqua-fortis; the solution being made, separate the Aqua-fortis again; then shall you have remaining a white Calx, which is fixed by the virtue of the Aqua-fortis: So that now it will admit of being molten with Lead, of being separated from the Scoria, and of being cupellated. But he that knows how to melt that Calx with Antimony and to precipitate it with auriferous Copper and Iron, gets more Gold than by that operation with Lead. But haply, every one can’t perform that separation; for the excoction or melting, the reduction into Scoria, and Cupellating upon the Test, are operations more known and easier to be done.

Moreover, there are also some Minerals, which may be fixed with the moist fire, that is, with a most strong Aq. fortis, so as to yield their Gold and Silver in the Scoria, but especially Tin, Quick-silver, and Lead: If a vehemently-strong Aq. fortis be but once abstracted from Tin, it makes it so fixt, as that it will not fly away in the greatest Fire, but will melt into a white Glass. But now, if you would have it to yield forth its Gold, you must melt other Metals with it, into which the Gold may insinuate it self, and be made corporeal, such as are Silver and Lead. Lead, if it be dissolved in Aq. fortis, and precipitated by Urine, it gets such a hardness, that it will scarce melt in a Crucible; if you precipitate it with a Lixivium, it becomes glassy; if with Salt-water, it is rendered exceedingly volatile; for common Salt makes all Metals volatile, and on the other hand, Nitre fixeth them both by the moist and by the dry way, binds them, and constrains them to abide in the Fire; and this you are to know aforehand. Now, for the better confirmation of this thing, see how easily the common Mercury is made to abide the fire, if Aq. fortis shall have been several times drawn off therefrom, insomuch that it will suffer it self to be made wholly red-hot. But now, if the same be sublimed with Spirit of Salt, it becomes more and more volatile, so amongst all Salts there’s not one that fixeth Minerals, save this most noble Nitre, and this hath a natural aptness to do it both by the moist and dry way, as hath been even now demonstrated.

And verily, this way of fixing the imperfect Metals (which is done by the help of Nitre, by either the moist or dry way) is to be preferred far before that which is done only with a Fire of Wood, not barely on this account, because it is sooner and speedilier performed, but for this reason too, because it fixeth better and more durably: For if any one shall endeavour to make Arsenick, Cobolt, or other volatile Minerals, permanent or fixt, by the bare force of common fire, How much time, I pray, must he allow it? Haply it will require some months for this kind of Work, if not a whole year, yet at least half a year ’twill need; whereas by the means of Nitre it may be done in one or two daies: For if a volatile Mineral be mixed with Nitre, do fulminate, and be edulcorated, and that fulmination be repeated 3 or 4 times, it will afterwards endure a sufficiently-vehement melting Fire. Or if a Mineral be only dissolved in Aq. fort. and that Aq. fort. again drawn off therefrom, it will even by this means be rendered fixt and constant in the Fire; so great is the force and virtue that lies hid in Salt-petre: And this the ancient Philosophers well knew, and therefore said that the most vehement fire of all was to be used to the fixation of volatile Minerals; and this fire is hid only in Nitre, and is no where else to be found; for the Central Fire hath too soon withdrawn it self from the volatile Minerals and baser Metals, and left them unripe, and they can be advanced to a maturity, both by our common Wood-fire, and by the fire of Salt-petre, and be fixed. And now I suppose that I have more than sufficiently proved, by what I have said, That Salt-petre fixeth Minerals and Metals, both by the dry and moist way; nor can any one reasonably deny the same. Moreover, I judge it not fit to pass this too over in silence, viz. That Salt-petre doth likewise make volatile, not only the unripe Minerals, but also the fixt Metals themselves; so as that they suffer themselves to be sublimed and destilled wholly (like common Sulphur or Mercury) save the fæces, which are somewhat blackish and stay behind. Any understanding man may easily consider here what benefit is to be hoped for from such a Destillation of Metals; for seeing that all things are by destillation brought to the highest purity (as is clearly evident) it may well be concluded, that when in impure metals the pure parts are separated from the impure, something of excellency must therefrom proceed. I will say no more of this matter at present, for I have already clearly enough demonstrated and plainly enough delivered this kind of destillation or purification of metals, in the third part of my Spagyr. Pharmacop. and have there shewn, that every imperfect metal, if it shall be destilled, yields volatile Gold, and that that volatile Gold may be made corporeal, without almost any Cost in a particular way, (and haply also in a universal, which I confess I have not as yet proved) thither therefore referr I the studious Reader of Hermetick and truly Philosophical Arcana and Secrets.

But that the difference of those waies of fixing or concentrating the volatile Minerals, and likewise the imperfect Metals, may rightly be perceived and laid open, and that it may appear how much more compendious and easie that way which is done by Nitre is than that which is done with common fire; it will be a good help to set down here some process for an example, by which it will be manifest how laborious this way of doing it barely with Wood is, and contrarily how easie that way of doing it by the moist Fire of Nitre is.

It is impossible to fix Arsenick, Auripigment, Cobolt, and such-like as these without the help of Saltpetre, unless they are first introduced into other metallick bodies, and are together with them, burnt with a Fire of Coals, and reduced into Ashes, and turned into Scoria, and wholly destroyed, and then at last reduced again into a metalline form, by the force of the intense fire of a Blast or Bellows: All which, that they may be dexterously performed, you must proceed on this manner, as followeth.

First of all, the Cobalt, Arsenick, or any Realgar like these, that is auriferous, is to be introduced into Copper or Iron by cementation, in the way that we have aforementioned; then the Copper or Iron thus cemented with the Realgars, is to be reduced into fine powder, and to be commixed with Antimony, Calmei, or Calaminaris, the Marchasite, and such order is to be taken, (if for Gains sake you would do a greater heap of matter) to have them slowly and by little and little made red-hot in Furnaces or Ovens, such as in which the flame may have room to play, and as’twere brandish it self at top of the matters, and stir them, and so let them be calcined and burnt into ashes, until they emit no more fume, and this will be in some few daies; then are they to be reduced in a convenient Furnace, and restored to their metalline form; then again must they be put into the former Oven, and there be calcined and burnt into ashes, still stirring them to and fro, and the ashes are to be reduced, by the vehement Blast of Bellows, and this ashifying and reduction is to be so long repeated, till there be a Regulus found in the reduction, and all the residue turns into unprofitable Scoria. This Regulus then is to be reduced on a Test into Scoria, and the Regulus being cupellated, the Gold and Silver which the volatile Minerals contained in them, doth shew it self.

NB. Altho’ this reparation is attended on with indifferent labour, yet notwithstanding (if there be a great quantity of matter dealt in) it is also gainful, especially where Minerals and Coals are to be had for a small price, and also the other imperfect metals (as Lead, Copper, and the like) that concurr in this kind of Operation; by which it also comes to pass, that there is a greater quantity of Gold and Silver extracted. For example, I burn Copper or Iron with Arsenick, Cobolt, and other poisonous volatile Realgars, or with bare Calmei only, which also avails to constringe or bind fast; with these I mix Antimony, Bismuth, Zink, and Lead, and melt them together: Hence ariseth a brittle mass, which is to be reduced into ashes, either in Ovens, as is already afore-shewed, with the flame of Wood, which darts it self at top of that mixt matter, and by heating ripens it, or by live Coals in a peculiar Furnace, and that on this wise: Let there be built a great or small Furnace, (of good Bricks or Tiles that will endure the Fire) according to the quantity of your matter which you take to prepare, let it be at least a foot over in the inside: in the forepart let it be open a foots heighth from the Pavement or Ground, to this end, that the Grate may be put in and taken out, as need is. Then some 2 or 3 foot higher than the Grate, let a door be made, whereby you may throw in the Coals, and above or at top of the Furnace are to be made Chimneys, fitted to receive and condense the fume of the metal, that it may not fly into the air, but being there cool’d, may be taken out. All this being done, fill the Furnace with Coals, and when they are well kindled, cast in a portion of your metalline mixture, which will quickly melt, and being melted, will run through the fiery Coals, and still keep fuming, and elevate it self up into the appointed Chimneys; that which melts down through the Coals and Grates, and is in the form of metal under the Furnace, (which bottom must be made somewhat shelving), that the metal which falls down may run into a hole or pit, is to be taken up with an Iron Spoon, and again thrown in upon the Coals, and this is to be so often repeated, and so long, till all your whole mixture be burnt into ashes, or carried up in fume, and so shall be ashified and sublimed in the appointed Tunnels or Chimneys, which Flores or metalline Fumes you must take and reduce them in a reducing Furnace, so part of them will pass into a fusile Metal, but brittle. This Metal now must be again ashify’d in that roasting or burning Furnace, and be reduced by blast of Bellows; and this ashifying and reduction is to be so often repeated, till all be seen turned into Dross or Glass; which Dross or Scorias are then to be reduced with the most vehement blast of Bellows, and so they will produce a Regulus which is to be cupellated with Lead, as is abovesaid.

NB. But if so be that of the last-made Scoria a Regulus cannot be made by the blast of the Bellows, and that the Scoria remain Scoria, ’tis a sign that you have taken too much Tin, or that your Fire hath been too intense; and therefore you must take such Scoria, and beat them to powder, and mix them with a little of either the fluid Ore of Lead, or Spume thereof, and make them flow in a reducing Furnace, then the Lead draws the Gold and Silver out of the Scoria, which may afterwards be cupellated. But as concerning the manner of making the roasting or ashifying Furnace, as likewise the fusing or reducing Furnace, I cannot indeed at present here decipher it, but I will do it in the Third Part following, where more such-like concentrations of Metals shall be mentioned and treated of. And farther, the well-minded Reader must also know, that this kind of Concentration is not at all written for those that are as yet wholly ignorant of the Art of melting metals, but for such only as have already sweated at the Fire, and have been often and much versed in such Separations or Liquefactions.

I question not, but there will be many that will despise this my way of operating, and count it an impossible thing, such are to be left to please themselves with their own fancies. But withal, some will be found, to whom the nature of metals is known, and these will give credit to what I say, and will abundantly profit themselves, especially in those places where Minerals, Coals, and other things requisite are to be had for a small price. The greatest Expence in this way of Concentration is the Coals, which too cannot be any thing much in those places where there are such vast Woods. Every one may have his liberty to try it or let it alone.

NB. But I do openly affirm, that if so be any one shall know how rightly to handle and manage this Work, it may be compared with the perpetual or alwaies-lasting mines; and where minerals may be had, it will be most gainful; but I will not perswade any to attempt it in those Coasts where all things are dear. Nor do I think it amiss to disswade them that have no experience in these kind of Operations, lest upon the ill management of the Operation, the effect should not succeed so luckily as they hoped for, and that then they should lay the blame upon me. That which I have at present written, is agreeable to the Truth, and may be successfully and gainfully performed by an experienced Artist or Laborator: And therefore as I have afore warned, so do I again advise the unexpert to abstain from this Work, unless he means to lose his Labour and Expences.

Such things as I have here omitted for brevities sake to speak of the Concentration of Metals, the Third and Fourth Part shall abundantly declare; but whoever he be that shall know how to bring to pass such a Concentration, either by the means of Salt-petre, by the dry way of a flame, or the moist way, by the help of Aq. fort. shall have a better effect than he that useth the Fire of Wood; but on the other hand, this Fire by Wood is of less Cost than the administration of the Work of Salt-petre is. Alas! What a deal of costs and labours have I bestowed in my life, in searching out and trying those kind of businesses, and having now brought it to this pass, as to be able to yield me the Reward of my Pains, I am not able to manage so vehement a fire, and to order the matters which require so great an heat? Therefore do I now with a willing mind make an offer of these my Experiments, to those who are of a vigorous age, and have Bodies capable of undergoing the toiling in the Fire. But that I may return to the things afore spoken of, and that that ashifying and reduction may not seem to the unexperienc’d altogether impossible and incredible, I will for their sakes bring undeniable Reasons or Arguments, whereby it shall be sufficiently enough evidenced, that such a cineration or turning into Scoria, hath its foundation in Nature, and that after this manner: Whosoever he be that hath seen or experienced somewhat in metals, knows, that the separation of the more excellent metals from the more vile, is to be done by the benefit of the Fire: for if so be that Gold, Silver, Copper, Iron, Lead, Tin, should be melted together into one mass, and you would separate them by the Fire the one from the other; this cannot be done any other way, but by adding to that mixture some other adventitious and destructive thing whereby the baser metals may be dissipated and deprived of their metallick form, of which sort is common Sulphur and such-like; for this works first on the imperfect metals, destroys them, or brings them into scoria and dross, which when they are so, and no more metals, they have no communion with metals, nor desire or love to be commixt with them afterwards: and by how much the more sulphureity there is in Metals, so much the easier doth common Sulphur destroy them and turn them into Scoria: But, by how much the nobler the metals shall be, so much the less detriment doth Sulphur bring upon them, and the less able is it to disturb (or alter) them. But besides, Sulphur does not only do this, but even the Fire, and Salt-petre both in the moist and in the dry way. It is done with Sulphur, if the metallick mixture be granulated and burnt therewithal, or that it be despoiled of the metalline Nature, then must it be molten and by precipitation be driven or be separated into divers Regulus’s. For the Sulphur converts the Mass into Scoria, which when they are molten, that which in them is the most noble doth always separate it self from the Scoria, and settle to the bottom; then next the most noble part comes other which is excellent, but yet short of the former, and so consequently it descends from one degree to another, as from Gold to Silver, from Silver to Lead, from this to Copper, from Copper to Iron, &c. as hath been by my formerly described separatory Art sufficiently enough shewn. But Nitre performs the separations it makes in a different manner: For after that the metallick Mass is molten in a Crucible, and that this (viz. Nitre) hath been thereinto put, it doth in the first place set upon the sulphureous part, and turns that into Scoria, then the baser Metal, and thus it does on, so long till it hath attracted all the imperfect Metals to it self, and reduced them into Scoria: and so the perfect Metals remain alone, pure; which order or governance of Operation, is also to an again, extant in my Writings.

Again, the bare fire is wont to keep another different way of destroying and scorifying Metals, than Sulphur and Nitre do.

For if a Metalline mixture be put in the fire, the more imperfect part thereof is consumed in the first place, and driven into ashes, the more excellent part gathers up it self into a globular form; and as long as it finds any consumable thing therein, so long does it work and act thereupon, nor leaves it off afore it hath reduced all into ashes. But that part which is of a constant and durable nature, remains unhurt by the fire; but yet if the combustible part be too much bigger in bulk than the abideing part, it does not only carry away with it the silver, but sometimes also a good part of the Gold, and brings it into ashes. And now, if those ashes shall be molten with a strong fire, then the ashes which arise out of the imperfect Metals, are turned into Glass, or scoria, but the ashes of the perfect Metals do reduce, and restore themselves into a malleable Body, whether it be Silver or Gold, according as it had this or that Metalline mixture in it; and if you proceed yet farther, with melting the aforesaid scoria in the fire, there will a new Regulus fall out, which contains in it that Metal, which is the noblest next Gold and Silver, viz. Lead, and Copper; the Tin, and Iron do for the most part abide in the scoria: Even as it is in Cupellation, or the separation of the Metals by the Cupel, the separation is there also done, by the bare fire only, and when the fire acts upon the mixture, it reduceth the Lead into scoria, or spume, or Litharge, and while this is reduced thus, it spares not the Tin, Iron, or Copper, forasmuch as they are likewise combustible, and of affinity thereto, but turns these together also into scoria, which said scoria do then creep, or sink into that penetrable, and porous Cineritious Vessel, or Test, as long as any of it remains: But the Gold and Silver which know not how to be thus burnt up into scoria or ashes, like the other imperfect Metals are left depured and cleansed upon the Cupel: The like also, is to be judged of the aforesaid incineration of Volatile Minerals, or imperfect Metals; that is to say, when they undergo the force of the fire, they cannot but go into scoria and ashes, and if they have in them somewhat that is especially good, and durable, yet the greater part being combustible, has the prevalency; so that the more excellent part which is in it, is converted together into ashes and scoria. But yet it may be afterwards reduced, for by the vehement blast of Bellows, it separates it self from the more base part, and again assumes a body Metalline, whether it be Gold or Silver.

By this Discourse any one that is not wholly void of all Metallick knowledge may see, that the Metallick Incineration and Reduction, which we have afore delivered, is built upon a firm foundation: But he that cannot understand or apprehend these things, is uncapable of being holpen by any art. But the following third and fourth parts will yield a more clear light, or instruction. Furthermore you are to observe, that there are likewise other ways whereby Metals are reduced into scoria, and the better and more excellent part is afterwards extracted out of the scoria, viz. by the help of Terrestrial things which are together, sulphureous, of which sort is all Sand, Flint, and the like. If ought of this kind be permixt and molten with the metalline Calxes, it retains with it the viler part, and lets go the more excellent; as for instance, there’s the Glass of Lead: For if the ashes of Lead be molten with Sand, or Flints, all the Lead together with the Flints is converted into Glass, or scoria, but the Silver or Gold which was in the Lead separates it self like a Regulus, and descends to the bottom.

Some kinds of Salts also are able to make those scoria’s, viz. those Salts which are extracted out of burnt ashes, and are commonly called Alkalies, such as are the burnt fæces of Wine, the Tartar of Wine, Potters-ashes made of the ashes of Wood, and other such like; these also love to dissolve the sulphureous parts of metals, and do leave the Gold and Silver that is therein whole and sound, and so make a separation of the good from the evil, and give them a notable splendour: Concerning which washing, we will treat more fully in the following third part.

Besides too, even common Salt destroyeth and reduceth the imperfect metals into scoria, but not after such a manner as Alkalies do by washing, but by dissolving and extracting. For if a metallick Calx, or Ore, be powdered and mixt with common Salt, and molten together, the Salt doth more readily seize upon the metal, than on the rest of the drossiness, dissolves it, and turns it into as it were scoria. But to illustrate this thing by an Example, If I would separate a mineral which hath in it, Iron, Copper, Gold, and Silver, and should melt it thus mixt with the Salt, then the Salt would the first time lay hold on the Iron only, and leave the other metals; but if so be there were not so much Iron, as for the Salt to satisfy its devouring self, it would dissolve the Copper too, the Silver and Gold remaining untoucht; for Salt is a common Enemy to Silver, but a Friend to the Iron and Copper, which it willingly dissolves in the melting, and attracts to it self, whether it be each apart by themselves, or both jointly together, which if you are minded again to separate each from the other, you must powder that molten Mass, and pour water thereupon, and boil it; so the Iron and Copper enters into the water, together with the Salt, whereinto if you afterwards put some Iron Rods, the Copper precipitates it self, and the Iron abides in the salt water, and is made very fit to use in dying like Vitriol; but if it will not be coagulated like Vitriol, then the Copper (which hath precipitated it self about the Iron) is to be washt and molten, out of which comes purer Copper. But yet such a Copper may be converted to better use than to be molten, of which more shall be spoken in the third part.

By this means, may one separate and bring into use those Coppery Minerals, which have much Iron in them, and by which, the Copper is otherwise rendered unmalleable and unprofitable: and this is such an Evil, as the Metal-workers have hitherto little known what remedy to apply; whereas in the mean while there lie in many places no contemptible Mines of Copper, neglected and unmedled withal, because they have Iron commixt with them. Some there have been, who have endeavoured to extract the Iron by the help of a Load-stone, but this way is too troublesom, and so is not profitable; but it may be aptly and conveniently done after this manner, did they but know how rightly to use here that aforesaid salt water, and the precipitated Copper: For the salt exalteth the Iron, and the Iron doth again exalt the salt, and animate it, so as that it may afterwards with a little labour and costs be, all of it, and without any loss, converted into good Salt-petre. But some or other may say, what profit would there redound unto me, if I should season one or two, or more Copper minerals with salt, whereby the Copper may be thence drawn out? I would have such an one to know, that in that Operation, some hundreds, or thousand pounds may be done together, and the business may be ordered upon fire in distinct Furnaces, that so a great profit may be gotten; and not only thus, but the same may likewise be done without any Furnace or Oven, with many hundred, or thousand pounds in one Operation, at the open Air in the Field, or in a Wood, where that Ore and salt are to be found; so that the salt may serve as a covering to the mineral, and the mineral as a covering to the salt, and the Wood may serve both for the Furnace and fire.

This now in my judgment is an artificial extraction of Copper out of the Mines, (especially when ’tis such an Ore), which (otherwise) is not of any profit by reason of the immixt Iron, or else consists of such a lean Vein of Copper, as will not suffice to quit the costs of getting it out, but yet it may by this means be separated, with no contemptible profit. For there are every where almost such poor Copper Ore as this which lie and are not dreamt of: For indeed it cannot be expected, that, (if when a Copper Mine (or Ore) doth contain in it some small matter of Copper, it being so overwhelmed as ’twere with the muchness of heterogeneal medlies or mixtures, that it cannot precipitate it self into Regulus’s but passeth into Scoria) it should answer the costs that are to be spent on the forcing it out; and therefore such Minerals must of necessity remain without use. And how many such kind of Ores have I found in Germany, which a man may have by heaps, but no body regards them, for that (as we have already said) they are too barren or poor: Whereas notwithstanding they may be most easily perfected by the help of Salt, so as to be made very gainful, & the costs exceedingly well repaid that shall be laid out upon them, especially in those places where there is such an abundance of Salt, that the Inhabitants know not what to do with the plenty they have of it. Many such places there are in Germany, as Tirole, Saltzburg, Bavaria, and the Diocess that we call Bergtes-gaden: in which places all the whole mountains do not only abound with Salts, but have no small portion of Copper too: Nor is it so in those places only, but likewise every where; Salt is common and of a small price throughout all Germany.

And as we have already shown you, that Iron and Copper may be commodiously extracted out of the Ores by melting it with common Salt, and may be again separated from each other by precipitation: So likewise may the same be done in a moist way by boiling; and is thus, if the Ore be ground and a long while boiled with very Salt-water, the Copper will be dissolved and passeth into the Salt-water, out of which it is to be precipitated, and so fitted for use. But now, if the Salt be distilled into a Spirit, then is it apt not only to extract Copper, but also Gold out of the Ore, and will be of exceeding much profit: But this operation hath already been long ago described by me, in the First Part of the Mineral Work.

NB. But it will be yet more profitable and gainful to prepare that water out of the Salts and especially out of Nitre, which water is but of small price, and yet notwithstanding it is of that Power and Virtue, as to dissolve or extract all the Metals out of the Ores: and as well the Silver as the Gold and Copper in the solution, may be again precipitated singularly or each Per se one after another; and this kind of water may you likewise use about all Fossiles or Ores with a most wonderful abbreviation.

But now, if you use common Aqua-fortis, it extracts only the Silver and Copper, and leaves the Gold: and if you take common Aqua-regia, it attracts only the Gold and Copper, and leaves the Silver; so that neither of these hath (as we use to say) all the points in it, especially seeing such a kind of Water serves but once only; nor is there as yet any one found who knows how to separate the metals in the solution one from another, so as that the water may still remain good and fit for other the like uses. But as concerning this Water of mine, thus stands the case, viz. One Metal may be precipitated after another out of the Water, and each distinctly, and yet for all this, the Water loseth not ought of its Virtue, but may be many times serviceable; certainly it is a most profitable invention, which (in the doing or perfecting some metals and minerals) is to be preferred many degrees before any melting by Fire. For if that there are several Metals of diverse kinds, in one Ore; as Gold, Silver, Iron, Lead (and this often happens so) and they should be forced out by Fire, they would yet remain mixt together; and there’s a great deal of work to separate them. For first they are to be cupellated on Tests with a great deal of Lead, that so the imperfect Metals, as the Iron, Copper, Tin and Lead if therein, may go off; then the Gold is to be separated also apart, or by a particular operation, by the help of a separating Water, and this is not every bodies work, nor have all such as are skill’d in the Art, in all places necessary provision at hand. But on the other hand, there needs not in that other kind of way, any thing save the Water and some Glasses, with these may you manage and compleat all the whole business, and get a great deal of gain without noise and trouble. For as to such a one as betakes himself to this kind of work, his Neighbours cannot accuse him, that he will (one time or other) ruine their Fortunes and Houses by Fire, for they hear no blowing of the bellows, nor see they any Coals carried into his House. Nor will the Smiths say that ’tis his fault that Coals are so dear, as ’twas objected to him who called himself the little Country fellow. Besides too, he will shun the suspicion of the Magistrates, nor will he give them occasion to suspect him to be a rich blade, and so torment him with the more grievous exactions and with quartering of Souldiers.

And now yet more, This kind of extraction does not only appertain to the getting out the Gold and Silver out of the Ores or Minerals and such as are volatile and crude, and which are every where to be met withal, and may without detriment to any, and with a safe conscience be fixed and separated by the help of this Water: But you may also by the mediation of this Water, profitably and with very small Labour separate all metallick mixtures, such as are mixt at their first forcing out of the Ores, or are melted into one Mass on any other account, and so obtain each Metal pure and free from all heterogeneities. As for example, Put case I have in my hands a certain metallick Mass, which hath in it Gold, Silver, Lead, Tin, Iron, and Copper: Now I would willingly separate the Gold & Silver therefrom: hitherto there hath been no other way known of obtaining it but by cupellating such a Mass or mixture upon the Test with Lead, and so depurating it; in which cupellation, the Copper, Tin, and Iron, do pass together with the Lead into the Test, but the Gold and Silver remain behind, which are to be afterwards separated with Aqua-fortis, that you may have each by it self. But the Iron, Copper, Lead and Tin do remain intermixt with each other in the Test, and should you again melt them even by the strongest blast, yet will they be commixt, and can hardly be separated the one from the other. But by this way of ours if they be dissolved in the water together, you may continually precipitate thence one Metal from another, and take them each apart, and not only the Gold and the Silver by themselves, but the Copper, Tin, Iron, and Argent-vive (each apart).

But it is not so necessary (if in such a metalline Mass wherein are contained so many Metals, the Gold and Silver be but the smaller part) to dissolve all the other baser metals together, to get out the Gold and Silver; this will not be advisedly done, but it would be better, first to purify that Mass upon a Test with Lead, and so to separate the Gold and Silver by the help of that water, or else that Mass may be burnt with Brimstone, and the Gold be thence precipitated and depured. But if the Mass hath less of Iron, Copper, and Tin, than of Gold, there will not be such need of purifying the Mass, by first burning it upon a Test, and then separating it by Aqua-fortis, as is commonly known and used to be done: but the whole mixture must be dissolved, and the Gold and Silver, which you please, be separately, or apart precipitated into a clean Calx, then the Copper also apart, then the Tin; but as for the Iron, you may forbear to precipitate that, because there are no great matters to be performed with its Calx, and it will be better to draw off the Aqua-fortis thence, whereby it may again be had pure, and fit for use.

Then the Iron which abides behind, if it be made red hot, yields a most excellent Crocus Martis, and a most excellent Ingredient for Chirurgeons, for all their Wound-balsams and Exicatory Emplasters; it is stictick; it will also be serviceable to Painters to make exquisite colours therewithal, so that the Iron which is the basest Metal in the whole mixture, if it shall be thus wrought upon and brought into good Crocus Martis, yields the money that was laid out upon the water, and yet this very water, after its abstracting from the Iron is not less fit for use, but is better than it was before. For in its abstraction from the Iron, it brought over with it some Goldenness, which Golden property doth afterwards, in other metallick solutions, associate it self to the Metals, is imbodyed, and yields as much Gold as the price almost (of the water) afore (thus used) could be judged at.
