TuffSilver Crystal is a toughenable highly reflective glass, that when painted looks like a normal annealed silver mirror. The semi-soft reflective coat is applied to a Low Iron Glass, to make the clarity even sharper. This means you can get the look of a silver mirror in a toughened state. The reflective surface is on the back of the glass and is directly painted onto, using a grey paint. This reflective coating is also available on an Euro Grey glass, giving a smokey grey mirror effect, this is called TuffSilver Grey.
