The Thermal Endurance of Glass. Part I.

JSGT_1924_V08_T139_T147

In spite of its practical importance, the theory of the thermal endurance of isotropic solids has been somewhat neglected, and in view of the desire of glass manufacturers to have a means of testing the relative values of different glasses considered apart from the actual forms and conditions of use of the manufactured articles, it will be useful to discuss the principles, as far as they are known, of the phenomena involved. It must be emphasised at the outset that these phenomena are exceedingly intricate and in the present state of our knowledge any explanations must necessarily be in some degree defective.
