Toughened glass is obtained by cutting ordinary annealed glass into required size, heating it to a near softening point, and then cooling it rapidly and evenly. After toughening, the surface of glass forms uniform  stress, while the interior forms tensile stress, which greatly improves the properties of glass. The tensile strength is more than three times of that of the latter and the impact resistance is more than five times of that of the latter.

It is precisely this characteristic that the stress characteristic becomes an important sign to distinguish the true and false tempered glass. That is, the tempered glass can see the color stripes at the edge of the glass through the polarizer, and can see the black and white spots on the surface of the glass. Polarizers can be found in camera lenses or glasses. When observing, pay attention to the adjustment of the light source, so that it is easier to observe.
