The bulk of the glass you see in commercial and domestic areas (think windows, doors, shower enclosures, microwaves, etc) has been tempered. This is due to the fact that tempered glass is extremely strong. Roughly 4 times stronger than "regular" glass, tempered glass will never simply crack. In the occasion that it does come across a blow big enough to shatter it, tempered glass shatters into small granules rather of sharp shards.
So what makes tempered glass a lot more powerful than annealed glass? The response lies within the production procedure. Here is how tempered glass is commonly made: First, the glass is cut to the preferred size. To ensure the stability of the glass, cutting need to happen prior to the tempering procedure starts.
Sharp edges are gotten rid of with an abrasive, like sandpaper. Then the glass is washed. After You Can Try This Source is prepped, it is sent through a tempering oven that heats up the glass to a temperature level of over 1,112 degrees Fahrenheit. (That's as hot as lava!) Next, the glass is cooled immediately through a high-pressure cooling procedure called "quenching".
When the center cools, it attempts to draw back from the outer surface area. This keeps the center in tension while the external surface area enters into compression. This is how tempered glass gets its strength glass in stress is about 5 times more breakable than glass in compression. January 4, 2019 techniglass, How Is Tempered Glass Made? 01.

One can determine whether the glass has been correctly tempered based upon the pattern in the glass breaks. Tempered glass is about 4 times stronger than "ordinary," or annealed, glass.
As a result, tempered glass is used in those environments where human safety is a concern. Applications include side and rear windows in automobiles, entrance doors, shower and tub enclosures, racquetball courts, patio furnishings, microwave ovens and skylights. To prepare glass for the tempering process, it must initially be cut to the desired size.
