| By heated flat glass in electric furnace to a fixed temperature then cool off rapidly, bend tempered glass with high strength can be produced. Similar to tempered glass, even if it fractures it will become small granular fragments, so that few injury by fragments will happen, therefore it is a kind of safe glass. |

| Bend tempered glass is made by laying an ordinary glass on a metal mold, which is made to specified shape, then heating and bending it by gravity itself, finally cooling it rapidly. Therefore, even if it fractures by impact beyond its strength, since fragments are granular, it prevents human bodies from being hurt deeply. |
