All the Float glass above, in both clear and obscure can be toughened for safety reasons.
Toughened glass withstands 5 times more impact before shattering, together with a higher tolerance to increased temperature. Tempering, by design, creates balanced internal stresses which causes the glass sheet, when broken, to crumble into small granular chunks of similar size and shape instead of splintering into random, jagged shards. The granular chunks are less likely to cause injury.
Laminated glass is s a type of safety glass that holds together when shattered. In the event of breaking, it is held in place by a clear interlayer between its two or more layers of glass. The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces. (Same as windscreen glass).
