IMPERIALITE is of no practical importance, but is interesting, as its history is that of the explosive one meets in the comic papers. The Marquis R. Imperiali had large private means and some knowledge of chemistry. He took out patents for a number of explosive mixtures and built a small factory in N. Italy, which started work in 1911. An explosion occurred the first day and killed five of the fifteen workers. Imperiali escaped and re-erected his factory. The day after it was restarted it blew up again and Imperiali was killed. The composition of the explosive that was being made is not known, but several of the mixtures for which Imperiali had taken out patents were decidedly dangerous.

*INDURITE was a smokeless powder patented by C. E. Munroe in 1893. It was made by incorporating guncotton with nitro-benzene to a hard mass. It was used for a time in the American Navy. Samples made in 1891 were still stable apparently in 1914, but some cases of instability occurred and it was given up.

*MISCHPULVER is a name given in German to ungelatinised smokeless nitro-cellulose powders.

MITCHELLITE was an explosive that was formerly licensed for manufacture in Great Britain, and was made at Bonnybridge, Stirling, but the factory and the licence were transferred to the M.B.

OXYLIQUIT is a blasting explosive consisting of liquid oxygen absorbed in some porous combustile material, such as absorbent cork, soot or kieselguhr mixed with petroleum. It was discovered in 1895 by Prof. F. C. Linde, and was tried on a large scale in 1899 in the construction of the Simplon tunnel. It is very cheap, and is safe in the case of a missfire, because in about half-an-hour the oxygen has all evaporated off and the charge becomes inexplosive. On the other hand, it is necessary to have the air liquefying plant near the scene of operations, and the charge must be fired soon after charging. These disadvantages prevented the adoption of the explosive, but during the War fresh trials were made in Germany in consequence of the scarcity of nitrates.

Liquid oxygen explosives are now used on a considerable scale by the Germans for military, as well as civil blasting operations. The name Oxyliquit, however, seems only to be applied to them when the explosive is made in the manner and with the plant of the Linde Company. See also Marsit.

PANCLASTITE.—A Sprengel explosive made by mixing liquid nitrogen peroxide with carbon bisulphide, nitro-benzene or nitro-toluene. It was proposed in 1881 by Turpin, and was tried by Germany for filling shell, the two constituents being contained in separate glass containers, which were broken by the shock of discharge. It was not adopted there on account of the inconvenience of dealing with a liquid which gives off poisonous fumes. It is a powerful and violent explosive, and is probably the same as the “Turpinite” about which sensational statements were made in the press early in the War.

There must also be not less than 4 per cent. of ammonium nitrate, and there may be an addition of sodium nitrate or other salt that does not increase the sensitiveness.

WETTER-PERSALIT is a similar explosive, but has been modified to make it more suitable for use in coal mines. It contains not more than 35 per cent. of potassium perchlorate, not more than 25 per cent. of ammonium nitrate, aromatic nitro-compounds of which not more than 20 per cent. must be trinitro-toluene, vegetable meal, not more than 6 per cent. of nitroglycerine, sodium nitrate, and neutral salts.
