What Is Tempered Glass?
Tempered glass is about four to five times stronger than regular glass because it goes though a controlled heating process. The process involves extreme heating of the glass in a tempering oven, followed by a rapid cooling to produce a hard outer layer. This type of glass is known by many different names, including safety, heat-treated, and thermal glass.
