Also known as toughened glass, is a type of safety glass that is processed to increase its strength and durability. It is made by heat-treating regular glass to reduce its thermal stress and increase its resistance to thermal shock. This process involves heating the glass to a high temperature, then rapidly cooling it using a quenching process. This process causes the outer layers of the glass to contract and become more dense, while the inner layers expand and become less dense. This creates a compressive stress on the surface of the glass, making it more resistant to breakage and shattering.

Where it is used:

Tempered glass is widely used in various applications where safety and durability are crucial. Some common examples include:

1. Automotive industry: Tempered glass is used in windshields, side windows, and rear windows of vehicles due to its high strength and resistance to impact.
2. Construction: Tempered glass is used in architectural glass applications, such as building facades, windows, and doors, due to its ability to withstand wind loads, seismic activity, and extreme temperatures.
3. Consumer products: Tempered glass is used in consumer products such as cookware, oven doors, microwave ovens, and refrigerator shelves.
4. Medical equipment: Tempered glass is used in medical equipment such as medical instruments, surgical equipment, and laboratory equipment due to its ability to withstand sterilization processes and prevent contamination.
5. Appliances: Tempered glass is used in household appliances such as stoves, refrigerators, and washing machines.
6. Furniture: Tempered glass is used in furniture such as coffee tables, shelves, and desks due to its durability and scratch-resistance.

Overall, tempered glass is an essential material in various industries where safety and durability are paramount.
