How is tempered glass different from ordinary glass?

From the perspective of security:
After the tempered glass is accidentally broken, the glass disintegrates into honeycomb shape with obtuse angles, which are relatively harmless to human body. Therefore, it is called safety glass, so it is widely used in various decorations glass.

From the perspective of high strength and deflection:
The strength of tempered glass is 3-5 times that of ordinary glass, and the deflection is 3-4 times larger than that of ordinary glass. Therefore, tempered glass is used in many places in life. The prices of tempered glass and ordinary glass are also different.

From the perspective of manufacturing principles:
Tempered glass is glass that has been subjected to a second heating and cooling tempering using ordinary glass. Its surface pressure is evenly distributed, and a certain tension is formed inside, which greatly improves the performance of the glass. The tensile strength and impact resistance are several times that of ordinary glass.

From the tensile characteristics of the glass:
True and false tempered glass can also be identified from the tensile characteristics. The tempered glass can form colored stripes on the edge of the glass through the polarizer, and can also see black and white spots on the surface of the glass. Polarized light sheets are easier to observe using professional polarizers.

From the side of the 70 degree point of view:
When viewed from the side of the glass at 70 degrees, it should be seen that the ordinary glass surface is smoother than the tempered glass. After tempering, the blue wind spots can be clearly seen. The tempered glass has a tempered mark on it, and if it is not, the tempered glass is produced by an informal manufacturer.
