Tempered glass is regular glass that is "cooked"and "cooled" very rapidly to lock the glass molecules in place. This Tempering process gives the final product a couple of unique features.  The strength of the glass from impacts, and temperate range is increased.  The newly temped glass is then able to with stand up to about 400 degrees.  It is used in low temperature fireplace doors - like bi-fold doors for this reason.  It is much cheaper to produce than Ceramic glass products that can withstand much high temperatures.  


Tempered should be used when standard glass could pose a potential danger. It is four to five times stronger than normal glass and does not shatter into large chunks when broken. Manufactured through a process of extreme heating (tempering) and rapid cooling, tempered glass is significantly harder than regular glass.

The tempered is much harder to break when hit straight on. ¬†But if broken this process causes it to shatter into small oval-shaped pebbles. This eliminates the danger of sharp edges. This is why along with its strength, this glass is often referred to as ‚Äėsafety glass.‚Äô ¬†The Tempering also raises the heat resistance up to about 400-500 degrees F. This is why this glass should be used in any situation where there is a danger of the glass breaking due to impact or extreme heat.

Tempered is one of two kinds of safety glass regularly used in applications in which standard glass could pose a potential danger. Tempered glass is four to five times stronger than standard glass and does not break into sharp shards when it fails. Tempered glass is manufactured through a process of extreme heating and rapid cooling, making it harder than normal glass.

The brittle nature of tempered causes it to shatter into small oval-shaped pebbles when broken. This eliminates the danger of sharp edges. Due to this property, along with its strength, tempered glass is often referred to as safety glass.

The thermal process that cures tempered glass also makes it heat resistant. Tempered is used to make the carafes in automatic coffee makers and the windows in ovens. Computer screens, skylights, door windows, tub enclosures and shower doors are more examples of places you will find tempered glass. Building codes also require the windows of many public structures to be made of tempered glass.
