3mm – 19mm Tempered Glass

Tempered glass is made by heating flat glass to just below its softening temperature and suddenly chilling it with jets of cold air. It results the outer skins under powerful compressive stress and the interior with severe tensile stress. In consequence, the impact applied to the glass will be overcome by the compression stress on the surfaces to assure safety of use.

Tempered safety glass has a much higher thermal shock resistance than float glass. Tempered safety glass can resist a thermal shock of as much as 150K, whereas float glass can only withstand thermal shock of 40K. Tempered safety glass is considered safety glass, however, primarily due to the way it breaks. Because it is in state of internal tension, when it breaks it shatters suddenly into small fragments with blunt edges, which considerably reduce the risk of severe injury.

Heat Soaked Testing

China 19mm-jumbo tempered-glass-heat-soaked-testing senhongA rare but nonetheless undesirable property of tempered glass is spontaneous breakage: tiny inclusions of nickel sulfide, invisible to the naked eye, expand in volume over time, and can cause the pane to break unexpectedly even years after installation. One reliable means of detecting nickel sulfide inclusions is the heat soaked test, in which the panes are warmed to about 290℃. During a soak time of about four hours in the heat soak oven, the tempered glass panes will nickel sulfide inclusion will probably break and hence never be installed in the first place.

Curved/Bent Tempered Glass

Bent or curved tempered glass is produced from flat glass that is heated to approx 600℃ to soften it and then brought into the desire form. Glass can be bent along one axis (cylindrically) or two (spherically), as for an all-glass domed ceiling, for example.
