You can not cut tempered glass because once a piece is broken the whole glass shatters. Tempered glass is safer because it breaks into tiny pieces rather than sharp edges like regular glass. The only way to tell if a glass is tempered is to break the glass or use a polarizer to detect stress waves. You will see stress waves in tempered glass verses regular glass. Hope this helps.
