Due to the fact that tempered glass breaks into uniform small particles without the sharp corners of typical glass blades, it is called safety glass and widely used in cars and interior decoration.

In homes, the sharp blade shaped corners of broken glass can easily cut children or impactors, causing damage to their bodies. The main difference between tempered glass and ordinary glass is whether the glass breaks into small particles or a blade shape. But in engineering inspections, it is undoubtedly unrealistic to always choose such destructive inspections.

So how can we know if what we bought is ultimately tempered glass?

This still needs to be analyzed from the principle of tempered glass production. Tempered glass is obtained by cutting ordinary annealed glass into the required size, heating it to a near softening point, and then rapidly and uniformly cooling it. After tempering treatment, the surface of the glass forms uniform pressure, while the interior forms tension, greatly improving the functionality of the glass. Its tensile strength is more than 3 times that of ordinary glass, and its impact resistance is more than 5 times that of ordinary glass.

It is precisely this characteristic that makes the tension feature an important indicator for distinguishing between genuine and fake tempered glass. That is, tempered glass can see colorful stripes at the edges of the glass through polarizing film, while black and white spots can be seen on the surface of the glass. Polarized light plates can be found in camera lenses or glasses. When conducting investigations, pay attention to adjusting the light source, which makes the investigation easier.
