1. Safety: when broken, tempered glass becomes small granules,
which prevent substantial hurt to human body.
2. High strength: the strength of tempered glass is 4 to 5 times
that of annealed glass.
3. Thermal stability: tempered glass has excellent thermal
stability, which can withstand up to **0°C thermal shock.
Tempered glass is a kind of safety glass and is widely used in
places which call for high mechanical strength and safety, such
as glazed door, curtain wall, vertical window, partition wall,
and partition screen close to heat source and subject to violent
thermal shock.
