How To Distinguish Ordinary And Toughened Glass

There are so many differences between tempered glass and ordinary glass, so how to distinguish them?

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.
And tempered glass has three characteristics
First :3C, CE, or other LOGO
Tempered glass must bear the certification mark, and ordinary glass does not carry this mark.   This sign cannot be erased or scratched.   If the markings can be removed easily, it is definitely not real tempered glass.   This is determined by the processing procedure of tempered glass.   First, the ordinary glass is cut according to the required size, and then it is edged, cleaned, and marked with the national certified 3C mark or other certification with ink, and then it can be fired at high temperature.
Second：glass shape
Ordinary glass is straight from the side and not curved, while tempered glass is not so flat and slightly curved when viewed from the side.   When comparing, you can stick ordinary glass and tempered glass face to face to see if there is any gap between the two.   The curved side is tempered glass.
Third:glass shards
The biggest difference between ordinary glass and tempered glass is the shape that appears after breaking.   The large pieces and sharp corners are ordinary glass, and the granular ones are tempered glass.
