The simple DIY procedure to cut tempered glass

Tempered glass is a safety glass that is designed in such a way that, on breakage, it shatters into small pieces. Tempered glass is prepared via thermal tempering. In this way, the glass is hardened by making it go under the heating treatment, which strengthens it and makes it safer and stronger than the conventional glass.

When the glass is tempered it causes compression on the outer surface and tension in the interior. Due to which when the tempered glass is broken it gets shattered into small pieces preventing the chances of accident and injury due to glass.
