Development of glass can be traced back to the mid-17th century, initially, there was a king named Robert Rhine son, has done an interesting experiment glass prices, he put a drop of molten glass was placed in cold water flat glass, The results made a very hard glass. This particulate glass high-strength tempered glass like water droplets, dragging with long curved tail, known as the "Prince Robert pellets." But when subjected to bending the tail pellets and broken glass windows, it is strange that the whole arabica therefore sudden severe crash, or even become a fine powder. The above approach, much like the metal quenching, which is glass quenching. This hardening does not make any change in composition of the glass, so it is also called physical hardening (physical tempered), therefore called tempered glass tempered glass, also known as tempered glass. Tempered glass, also known as tempered glass. It is a physical or chemical method, on the glass surface to form a compressive stress layer, the glass itself has a high compressive strength, without causing damage. When the glass by external force, the pressure level can be partially offset by tensile stress, avoid fragmentation of glass, although glass inside in a large tensile stress, but no defects within the glass, will not cause havoc in , so as to achieve the purpose of improving the strength of the glass.
