What is heat strengthened glass?
A. Heat strengthened glass is twice as strong as non-tempered glass and must have a surface compression of between 3,500 and 10,000 psi, or an edge compression of 5,500 and 9,700 psi. Fracture characheristics of heat strengthened glass vary widely from much like annealed glass to similar to fully tempered glass. For this reason, heat strengthened glass does not qualify as a safety glass.
