Continuing on our promise, we will be marking our 90th Anniversary throughout the year with the release of several more of our Legacy White papers.

In 1959, Dr. Richard Mould in collaboration with Mr. Russell Southwick, both of Preston Laboratories, the predecessor and foundation of American Glass Research,

 prepared two papers entitled "Strength and Static Fatigue of Glass under Controlled Ambient Conditions, Part 1 and 2" that further defined glass strength and how it should be properly measured.

 That was immediately followed by two papers by Dr. Mould under the same title as Parts 3 and 4 in which he further defined critical aspects of glass strength.

 We hope you find all four of them interesting. Visit our White Papers Library to download all four and to view all of our White Papers.
