Annealed Glass

Annealed glass will break into large shards.

Annealed glass is the result of a cooling process that glass undergoes after being produced in our factory. A piece of glass must be cut while in the annealed form, prior to undergoing additional processes such as heat-strengthening or tempering. Once a piece of glass has been heat-strengthened or tempered, it will shatter if cut.
