An X-Ray Investigation of Felspar Glasses
JSGT_1929_V13_290_T296
The constitution and structure of glass have long been a puzzling problem. The accepted opinion now is that glass is a supercooled liquid, a solution of various metal oxides in silica. Data on specific heat, surface tension, melting point, viscosity, and dielectric strength indicate that the material is of high molecular weight or highly associated. For a more thorough discussion of the current information on the· constitution of glass the reader is referred to a collection of papers entitled, “Constitution of Glass” from the Journal.
