Toughened glass is up to five times stronger than ordinary glass and when it does break it breaks into many tiny pieces which reduces the chance of injury. Toughened glass cannot be cut once toughend and cannot be acid etched but it can be sandblasted.
Laminated glass has the same strength as ordinary glass and consists of two layers of glass with an interlayer. If the glass breaks it stays in one piece. Laminated glass can be acid etched, sandblasted and cut to size.
