Tempered glass, known for its strength and durability, is a type of safety glass processed by heat treatment. This process involves heating the glass to a high temperature and then rapidly cooling it, a technique known as quenching.

Manufacturing Process of Tempered Glass

The manufacturing process of tempered glass begins with cutting the glass to the desired size. The glass is then heated in a tempering oven to a temperature of around 600°C (1112°F). Once heated, the glass is rapidly cooled using jets of air, a process that strengthens the glass by creating compressive stresses on its surface.

This tempering process gives the glass its enhanced strength and durability, making it more resistant to thermal stresses and impacts.

Key Properties and Characteristics

Tempered glass has several key properties that make it a preferred choice in various applications. Some of its notable characteristics include:

• Enhanced Strength: Tempered glass is several times stronger than regular glass, making it more resistant to impacts.
