Annealed glass is the result of a cooling process that glass undergoes after being produced at a glass factory. A piece of glass must be cut while it is 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.


If annealed glass is impacted, it will break into large shards.Annelaed glass breakage pattern
