TOUGHENED GLASS

Toughened or tempered glass is a safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal annealed glass. Tempering puts the outer surfaces into compression and the inner surface into tension. Such stresses cause the glass, when broken, to crumble into small granular pieces instead of splintering into dangerous jagged shards as plate glass creates. The granular pieces are less likely to cause injury.

PERFORMACE DATA

Toughened or tempered glass is a safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal annealed glass. Tempering puts the outer surfaces into compression and the inner surface into tension. Such stresses cause the glass, when broken, to crumble into small granular pieces instead of splintering into dangerous jagged shards as plate glass creates. The granular pieces are less likely to cause injury.

Heat soaking is a method of reducing the incidence of spontaneous breakage in tempered glass caused by nickel sulphide inclusions.

Spontaneous breakage is a destructive process where the physical changes generate sufficient stresses to break the defective glass.

It is estimated that up 95%of nickel sulphide contaminated panels of glass are usually eliminated by this process and thus the chance of on site spontaneous breakage is significantly reduced.
