Toughened or tempered glass is a type of safety glass processed by controlled thermal treatments to increase its strength compared with normal annealed glass.
The glass is cut to the size required and then its edges are arisen. It then goes through a toughening furnace where the glass is heated up very quickly and then quenched and cooled very quickly. This process of taking the glass up to 750 degrees and then cooling it, changes the molecular structure of the glass and gives it a very high outer tensile strength.
When broken, toughened glass breaks into small, relatively harmless pieces of glass which minimize the risk of injury. It is used in an increasing amount of applications where safety glass is required such as doors, side screens and low level glazing.
