Most of the glass you see on a regular basis is probably tempered glass. Tempered glass is used in windows, computers, appliances, vehicles, doors, and more. Here are some of the reasons why:
Tempered glass is approximately 4x stronger than annealed glass, or “ordinary” glass. Tempered glass gets its strength from the thermal tempering process used to manufacture tempered glass. During the quenching step (a high-pressure cooling procedure), the outer surface of the glass goes into compression. Glass in compression is about 5x less breakable than glass in tension. The end result – tempered glass that can withstand direct blows, powerful winds, and minor explosions.
Tempered glass is designed for safety. In the event that it does encounter a blow large enough to shatter it, tempered glass breaks into small granules instead of sharp shards. This safety precaution is another reason tempered glass is so widely used.
Tempered glass can withstand temperatures up to 470 degrees Fahrenheit. Because it is heat resistant, tempered glass is ideal for kitchen appliances and for use in areas that may regularly be in contact with heat.

The thermal process that makes tempered glass so strong also makes it scratch-resistant and preserves the clarity and transparency of the glass. This is one reason car windows, phone screens, and glass doors are made of tempered glass.
Tempered glass is available in a variety of different designs and patterns, making it perfect for use wherever glass is needed.
