Tempered glass is a single piece of glass that is strengthened through a rapid cooling process. This cooling process tempers the glass by blasting both the top and bottom surfaces with air. The outside surfaces of the glass cool faster than the core of the glass. This action sets up a balance of strains between the surfaces and the core which adds considerable strength to the glass. Tempered glass is difficult to break, but if broken it breaks into small granular pieces.
