What is the difference between tempered glass and ordinary glass?
1. Different strength: the bearing capacity of tempered glass is 3 to 5 times that of ordinary glass. Under the same thickness, the impact force of tempered glass has little influence.

2. Different hazards: When ordinary glass is broken, the edge is sharp and the hazard is great. The tempered glass is broken into particles, which is less harmful.
3. Different temperature resistance: Tempered glass has good thermal stability and can withstand a temperature difference of 150°C without bursting, which is three times that of ordinary glass.
4. The construction is different: ordinary glass can be cut with a glass knife, but tempered glass cannot be cut or processed again.
5.The essence is different: tempered glass is made of ordinary glass by chemical or physical methods.

Tempered glass is stronger than ordinary glass and breaks into small, relatively harmless pieces due to a specific manufacturing process that introduces internal stresses and modifies its molecular structure. This process is known as tempering, and it imparts several key properties that make tempered glass stronger and safer:
1. Surface Compression and Internal Tension:** During the tempering process, tempered glass is heated to a high temperature and then rapidly cooled using jets of cold air. This rapid cooling causes the exterior surfaces of the glass to cool and contract more quickly than the interior, creating surface compression and internal tension within the glass. This results in a state of balanced stress that contributes to its strength.
3. Breakage Pattern: When tempered glass does break, the internal tension causes it to shatter into small, granular pieces with rounded edges. These small pieces, known as "dice" or "cubes," are less likely to cause severe cuts or injuries compared to the sharp, jagged shards that ordinary glass produces.
4. Stress Distribution: The controlled distribution of stress throughout the tempered glass helps prevent concentrated stress points that can lead to cracking or breaking. This uniform stress distribution contributes to the glass's ability to withstand impact and thermal stresses.
There are so many differences between tempered glass and ordinary glass, so how to distinguish them? Next Tuesday we will teach you how to distinguish tempered glass from ordinary glass.
