Breaking A Sheet Of Tempered Glass

Thick industrial paper is used to catch the broken tempered glass.

Breaking a sheet of tempered glass.

Here we break a large sheet of tempered glass to see the amazingly fast crack propagation followed by the crashing down of the shattered glass. Tempered glass is used where there is a likelihood of human contact and as such is made to shatter into small pieces when broken. Spontaneous breakage in tempered glass is however much more dramatic as the whole pane of tempered glass breaks with a loud noise and high visibility as it breaks into thousands of small pieces. Most of the time spontaneous glass breakage is the result of improper annealing of the glass by the manufacturer or thermal shock of the glass during normal usage.

The glass breakage is shown full speed half speed. These breaks tend to be linear and not circular. Pull a glass out of the oven or dishwasher when it is hot and place ice water into the glass and it may break due to thermal shock. Dress in a long sleeved shirt long pants and.

Always wear protective clothing when working with glass. Any non tempered glass will normally break as a single crack or multiple cracks which develop or propagate from origin either spontaneously or gently. Breaking tempered glass at work. Spread a 10 foot length of industrial paper.
