Description
Tempered glass is produced by heating ordinary ("annealed") glass to near its softening point and then rapidly cooling it. As the outside surface of the glass cools first, tension is created between the inner thickness and the outer surface. This compresses the surface and the edge of the glass. The result is a hardened surface and a stronger glass.

Characteristics
     Approximately 4-5 times stronger than ordinary glass
     Can withstand high heat up to 260ºC (500ºF)
     In the event of breakage, the glass will shatter into small cube-shaped
      fragments
     More economical than Pyrex®

Applications
     Light lenses (e.g., halogen, custom-made light fixtures)
     Fireplace doors, doors, windows, tabletops, shelving, desktops,

     Barbeque ovens
     Bus shelters
     Greenhouse glass
