What is toughened glass?

This style of glass can often be referred to as “tempered” which is derived from the fact that it is heated to roughly 650℃, only to be swiftly cooled again. It is this process which directly impacts the strength of the glass, providing up to five times the ordinary strength of glass.

Both the thermal strength and shock-resistance are increased with this process of toughening applied. A resilient material, it cannot be cut again once it has been toughened, this means the size and shape should be decided prior to treatment.

When shattered, toughened glass breaks into very small pieces with blunt edges. This makes it a safer style of glass when damaged.
