Toughened / Tempered glass is a safety glass that has undergone processes of controlled thermal treatment to increase its strength. It is made from annealed glass that has been heated to approximately 650⁰C and then rapidly cooled, making it significantly stronger than ordinary glass.
Due to the increased heat treatment and rapid cooling of the glass, the treatment produces different physical properties. This results in compressive stress on the surface and improved bending strength of the glass. Before toughening, the glass must be cut to the correct size or pressed to shape.
The glass is carried by rollers and goes through the furnace. The glass is then heated through three different modes — conduction, convection, and radiation. While the rollers help to conduct the heat, the coils enable the radiation. This ensures that the glass is evenly heated on every side. The heated glass is then cooled uniformly by blasting air on both surfaces.
What is toughened glass?
Glass that has been subjected to a controlled heating and cooling process, in order to significantly increase its resistance to mechanical and thermal stress. Through the thermal toughening process, the glass attains its safe-breakage characteristics.
Is it possible to cut toughened glass?
It is possible to cut and toughen a glass but after toughening glass cannot be cut.
Is toughened glass good for home?
Toughened glass is a prefered material for home to ensure added safety
What are the benefits of toughened glass?
Toughened glass has high withstanding capacity and is therefore suitable for uses where strength and thermal resistance are crucial.
How does toughened glass break?
In the rare event of breakage, toughened glass shatters into small, pebble-like pieces.
How is glass toughened made?
Toughened glass or tempered glass is the glass that has undergone processes of controlled thermal treatment to increase its strength.
Which glass is used for balcony railing?
