What is a key characteristic of tempered glass?

Tempered glass is specifically known for being chemically treated to increase its strength, making it more resistant to impact and thermal stress compared to regular glass. This treatment process involves heating the glass to a high temperature and then cooling it rapidly, which alters the internal structure of the glass, creating a stronger product that can withstand greater physical forces.

The enhanced strength of tempered glass is a key characteristic that makes it especially suitable for applications where safety and durability are critical, such as in shower doors, glass doors, and windows. When broken, tempered glass shatters into small, blunt pieces rather than sharp shards, which further contributes to its safety benefits.
