Tempered glass is made from annealed glass via a thermal tempering process in which the glass is heated till its softening point about 650 degrees and then quenching quickly to become tempered glass or heat strengthened glass

Steps of Manufacturing

Step I
First and foremost the right glass combination is selected according to the clients' requirement. The choices are limitless, Clear, Tinted, low-e reflective etc.

Step II

The glass is then cut to size and then its edges are treated.Holes and cutoutsare then drilled onto the glass. Then the glass is washed by deionized water and loaded onto the transportation bay of the furnace

Step III

The glass is then transferred into the heating chamber of the tempering furnace. Here the glass is heated till its softening point

Step IV

The glass that comes out at the other end of the furnace is either a fully tempered glass or heat strengthened glass depending upon the operating cycle set by the operator in accordance with the client's order.

Characteristics

A fully tempered glass is 3 to 5 times stronger than annealed glass. A fully tempered glass is regarded as a safety glass and when it breaks it disintegrates intosmall blunt pieces/small oval-shaped pebbleswhich greatly reduce the chances of injuries

1) Strength - Fully tempered glass is generally 3 to 5 times stronger than annealed glass and twice as strong as heat strengthened glass of similar thickness, size and type. For fully tempered glass the minimum surface compression is 10000 psi and for a heat strengthened glass is 4000-7000 psi for 6 mm glass

2) Safety - When broken by impact, fully tempered glass immediately disintegrates intosmall oval-shaped pebbles, thusgreatly reducing the likelihood of cutting person
