Toughened Glass

Tempered glass has a very good performance of anti-cirve, anti-hitting, 3 to 6 times better than normal glass. It can afford pressure over 95MPa on the surface. It has high stability even under temperature changing from 200 to 300 while normal glass can only afford change of 70-100. It becomes small sand shape if is broken under big force, which guarantee safety and less loss.
