T/F

Explanation:

Tempered glass is harder and stronger than annealed glass. When tempered glass breaks, it breaks into small pebble shaped pieces like a car's side glass after an accident. This is why it is often called safety glass. Tempered glass is annealed glass that has been heat treated to harden and strengthen it.
