Is there a difference between tempered glass and ordinary glass?

Tempered glass with compressive stress on its surface. Tempered glass is different from ordinary glass in that it has high strength and thermal stability. Moreover, tempered glass can see the color bar through the polarizing plate and the edge of the glass. Moreover, when the glass is damaged by external force, the fragments will become small particles similar to honeycomb, which is not easy to cause serious harm to the human body.
