Tempered Glass, on occasion, can experience spontaneous breakage due to inclusions such as nickel sulfide, which can occur during the glass-making process,

Tempered Glass is called "safety glass." However even glass which is fully tempered is susceptible to breakage. Tempered Glass may occasionally break in large shards, rather than in the classic tiny piece pattern, and some injury may result.

Characteristics

Approximately four times stronger than annealed glass of equal thickness Greater resistance to thermally induced stress than heat-strengthened or annealed glass Suitable for use as a safety glass as defined by Consumer Product Safety Commission I 6 CFR I 201, ANSI Z 97.1, 1984 and Canadian standard CAN/CGSB-12.1-M90 Tempered safety glass may also be mandated in other parts of the world by individual country regulation codes or specifications
