Description
A high strength plate glass. Tempered glass is a plate glass that has been reheated and held above its annealing point (650C or 1200F), then flash cooled. The tempering process produces glass that is 3-5 times stronger than ordinary plate glass of the same thickness (Konrad, 1995). However, it cannot be cut or ground. Tempered glass was first used in 1942. It is used for large doors and automobile windows. On impact, tempered glass shatters into small round-edged pieces.
