Tempered Glass
鋼化玻璃
是由浮法玻璃经过快速冷却热处理而制成，强度较 浮法玻璃高4至6倍，且破裂时只会形成小的碎片， 不会有大块锋利的碎片。但在强化后，强化玻璃上 有任何损坏或裂痕，都会造成整片玻璃的碎裂。
Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension. Such stress would cause the glass, when broken, to crumble into small granular chunks instead of splintering into jagged shards as plate glass (a.k.a. annealed glass) does. The granular chunks are less likely to cause injury.
