Tempered glass is regular glass cut to the required size and softening point of liquid heated to about 700 degrees, derived from a fast uniform cooling (typically 5-6MM glass heating at 700 degrees to 240 seconds, cooling down about 150 seconds. 8-10MM glass heating at 700 degrees to 500 seconds, cooling to 300 seconds. In short, according to the glass thickness, selecting heating and cooling time). Tempered glass uniform pressure on the surface after stress, while the internal formation of tensile stress, led to increased flexural and impact strength of glass, which is about four times more than the ordinary glass. Which have already been tempered glass, can no longer be any cutting, grinding, machining, or broken, or damaged uniform compressive stresses balance and "pieces".
