Tempered glass is an ordinary transparent sheet type material. It is created by heating to a temperature of 650-680 ° C. After reaching this mark, there is a sharp and uniform air cooling. Due to the use of this technology, residual compressive stresses appear, which allows achieving maximum strength, reliability and resistance to temperatures. Moreover, if such tempered glass breaks, it will cause less harm to others than ordinary glass. This is due to the fact that when destroyed, the material is crushed into blunt small fragments that are not capable of causing really serious injuries.

It is about the protected glass, its use in industry, we will talk in the article. We will also consider how such material is created and what is its interaction with modern gadgets.


Due to such properties of tempered glass as safety and strength, it is often used in construction, railway, automobile, furniture industry, psychiatry. Moreover, it is used to create dishes, showcases, barriers on hockey rinks.

Another useful feature is tempered glass - heat resistance. What is itlets do? When glazing houses and premises, there is no risk of exposing the substance to thermal shock. That is, such a material can easily withstand even the strongest temperature changes.

What can make the described glass vulnerable? Just a kick to the butt. Such a mechanical impact can easily destroy the tension of the glass and completely break it. This effect is used in modern design styles. Sometimes they install a door with glass inserts with decorative cracks on it. These small flaws come together to create a spider web pattern.

Tempered glass cannot be drilled, cut or otherwise processed.

Such material can protect the device from scratches and other deformations. However, not all blows he is able to withstand. Therefore, due to even the slightest damage, the transparent product may break.

Vacation is a method that strengthens any glass products. It can be either a jar, a glass, a salad bowl, or a completely different dish.
