Tempered glass

Tempered glass is a special process that makes the glass shatter into very small pieces. The glass takes a heat application on a tempering oven of more than 1112 F, then the glass goes to a quenching cooling for a few seconds provoking tension inside and compression outside. The glass will break in 6000 psi (pound per square inch)
