Glass tempering technique, also known as heat treatment, is a procedure used to increase the durability of glass by changing its stress pattern. This process involves heating to a high temperature, and then rapidly cooling it.

The glass is typically heated to around 600-700 degrees Celsius, depending on the type of glass and the desired level of tempering. At this temperature, the glass is soft and pliable, allowing the manufacturer to apply a stress design to it. The stress pattern is what gives the glass its strength and resilience.

After the glass has been heated to the desired temperature, the manufacturing process continues with a rapid cooling process. This is where the glass is exposed to a controlled stream of air that rapidly cools the glass down. The rapid cooling process creates a compressive stress on the surface of the glass, which helps to balance out the tension in the center of the glass.

The rapid cooling process can be achieved through a variety of methods, including spray cooling or rapid air cooling. The choice of method depends on the type of glass and the desired level of tempering. Once the glass has been cooled, it is inspected for any irregularities or imperfections.

One of the key benefits of foggy glass window repair tempering is its ability to increase strength. Tempered glass can resist pressure that would break regular glass. This makes it a popular choice for safety-critical applications, such as in construction and automotive and marine industries.

In addition to its increased strength, tempered glass also has a number of other benefits. It is resistant to thermal stress without shattering. It also has a higher scratch resistance and is more resistant to corrosion than regular glass.

In conclusion, glass tempering is a process that involves heating and cooling to create a compressive stress on the surface. This process improves durability, making it a popular choice for safety-critical applications.
