Toughened or tempered glass is a type of safety glass that has been strengthened by regulated thermal or chemical treatments in comparison to ordinary glass. Tempering causes internal stresses that cause the glass to crumble into little granular fragments rather than fracture into sharp shards when broken. The granular chunks have a lower risk of causing damage.
Tempered glass is utilized in a range of demanding applications due to its safety and strength, such as shower doors, glass doors and tables, bathroom windows, and so on.
A thermal tempering method is used to create toughened glass from annealed glass. The glass is put on a roller table and passed through a furnace where it is heated above its annealing temperature of roughly 720 degrees Celsius. The glass is then swiftly chilled using forced air drafts, with the inner portion of the glass remaining free to flow for a brief period of time.
