GT V01 1960 115-120

An historical summary is presented of the development of photosensitive glasses and of materials associated with the Fotoceram and Pyroceram trade-marks. Various fundamental and technical problems encountered in their production are discussed. Properties of two currently standard varieties of glass-ceramic are compared with those of heat-resisting glasses and alumina ceramic, and some of the applications of glass-ceramics are mentioned.
