What is the difference between tempered glass and crystal glass?

Crystal glass: Crystal glass is called artificial crystal. Due to the scarcity of natural crystal and its difficulty in mining, it cannot meet people's needs, so artificial crystal glass was born. Due to its high transparency, it can be made into various handicrafts and is greatly favored by the world.

Tempered glass: (Tempered glass/Reinforced glass) belongs to safety glass. Tempered glass is actually a kind of prestressed glass. In order to improve the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass. When the glass is subjected to external force, it first offsets the surface stress, thereby improving the bearing capacity and enhancing the resistance of the glass itself. Wind pressure, cold and heat, impact, etc. The typical tempered glass is painted tempered glass, commonly known as "photographic film". This product uses ink smear technology to make the painted pattern appear on the film, so as to achieve the effect of painted glass, and its product has low environmental performance.
