ABSTRACT:
In the encapsulation of insert materials within glass and glass-ceramic articles, not only must the bonding characteristics between the insert and the glass or glass-ceramic materials be considered, but also the relative coefficient of thermal expansions between the insert and the encapsulating materials must be programmed in order to avoid undue stresses in the article or the insert which could produce deleterious results.
