What Is Tempered Glass And How It Is Made?

By Joseph Devine


Tempered glass has proven to be a wonderful solution to regular glass because it is much stronger than annealed ordinary glass. Unlike the annealed glass material that may simply shatter into pieces when broken and even roughly used, glass suppliers now offer tempered glass that will fracture into tiny pieces, relatively harmless. Therefore, tempered glass in mainly utilized in households as a measure to protect the environment and for safety as well. Applications of this form of glass includes rear and side windows in entrance doors, vehicles, tub and shower enclosures, patio furniture items, racquet ball courts, skylights and microwave ovens.

Tempered glass is one type of glass that is known to be very important to the safety of vehicles. Although it'd apparently seem to be the same as laminated glass, it's not. There is plenty of difference in both these forms of glass and their functions. This glass type is mainly used for the purpose of surrounding windows of vehicles also known as sidelites. Also, these are used for the back windows or backlite. Tempered glass could be created by heating up and eventually cooling the material to its room temperature by passing it through blowers.

The glass surface tends to cool down on its center and eventually contract, thereby creating compressive stresses on it. However, the center part of this glass expands because of the temperature that produces tensile stresses. Before selecting a glass supplier, people must also check out the differences between tempered utility glass and the ordinary glass so that the difference is noticed.

The typical tempered glass material is usually quite weak. This is mainly the results of rapid heat released throughout the phase of cooling of tempering process. So as to compensate for weaker areas, this glass used is to be ground down on its edges. As the tempered glass tends to break, it unusually shatters and crumbles into dull, small pieces. There's a subtle difference between tensile stresses and compressive stresses, and this is mainly responsive to breaking glass. The pushing and pulling of glass produces certain amounts of energy when the process of tempering is on. As the glass is breaking, energy is gradually released, and this causes glass material to break further into smaller pieces.

Tempered glass is often much stronger than any other form of glass. This is one of the the reason why tempered glass can actually withstand automobile driving and others harsh effects too.
