(The market requirement is 620 degrees Celsius.) The glass then goes through a high-pressure cooling treatment called "quenching." During this process, which lasts just seconds, high-pressure air blasts the surface of the glass from a range of nozzles in differing positions. Satiating cools the external surface areas of the glass much more quickly than the center.

As an outcome, the center stays in tension, and the outer surface areas enter into compression, which gives tempered glass its strength. Glass in stress breaks about five times more quickly than it performs in compression. Annealed glass will break at 6,000 pounds per square inch (psi). Tempered glass, according to federal specifications, must have a surface compression of 10,000 psi or more; it usually breaks at approximately 24,000 psi.

However since this technique costs even more than utilizing tempering ovens and quenching, it is not extensively used.

Tempered glass, or toughened glass, has actually been heat-treated to make it more powerful and safer to prevent injury in case if it ever breaks. In  You Can Try This Source , tempered glass is four to five times more powerful than annealed, or without treatment, glass. In the event of damage, tempered glass fractures into little, relatively harmless pieces instead of rugged shards.

Some Known Details About How to Temper Glass - wikiHow

Typical applications consist of side and rear windows in vehicles, entrance doors, shower and tub enclosures, racquetball courts, outdoor patio furniture, microwave ovens, fireplace doors and grates, and skylights. Tempered glass is also used for interior railings, display cases, workplace walls, and anywhere else where robust, resilient glass is required. Glass tempering occurs following the fabrication process via the following steps.

If a manufacturer attempts to engrave or edge a piece of glass after the heat treatment has been done, the finished product will likely be weaker and more vulnerable than meant, increasing the probability of damage and product failure. Fractures or bubbles may cause the glass to break throughout any part of the tempering process; if any defects are found, the glass can not be tempered.

In order to temper glass properly, the operator must pick the right recipe based on glass type and thickness. This consists of cycle time, temperature, quenching and cooling pressure. The heated glass is subjected to seconds of high-pressure blasts of cool air, a process understood as quenching. The quick cooling causes the outer surface areas of the glass to cool and contract faster than the interior.
