Tuffen glass

Listing ID #3514014

Toughened Glass or Tempered Glass has increased strength and is widely used for its safety as it usually shatters into small fragments in the event of an impact. It is usually installed in areas where safety glass is required to lessen the possibility of mechanical or thermal breakage and or to assure greater uniform load strength.
Glass is tempered by taking annealed glass and heating it to softening point of approximately 660 degree C. Its structure is then rapidly cooled while the inner core is allowed to cool gradually. This results in layer of high compression on the surface counter balancing by high tension at the center resulting in a glass that is four to five times stronger than annealed glass. Should accidental breakage occur, the resulting fragments are smaller and granular, causing no injury, harmless.
