Some Implications of the Known Variation in the Strength of Glass

JSGT 1934 V18 T194-T200

 The following paper is written in the hope of directing the attention of glass technologists to various points which are sometimes overlooked, but which are implicit in the known variation of certain physical properties of glass. In the course of the last ten years we have had occasion, in the development of glass to resist temperature shocks, to collect data on the tensile strength of different types of glass and on thermal endurance. The most striking feature about these results is the variation in the property which occurs between one article and another when these are both made from the same batch materials.
