The Methods of Glass Blowing and of Working Silica in the Oxy-Gas Flame / For the use of chemical and physical students

The manual provides step-by-step practical instruction for laboratory glass-blowing and for working vitreous silica in oxy-gas flames. It describes required apparatus and flame types, contrasts the handling of different glass varieties, and gives detailed techniques for cutting, bending, sealing, welding, blowing bulbs, and making stoppers. It explains construction and joining of complex assemblies, air-tight and mercury joints, vacuum and safety taps, and methods for graduating and calibrating measuring tubes and thermometers. A final section treats properties of vitreous silica, methods for preparing and forming silica tubes and fibres, and precautions for manipulating this more refractory material.
