What is tempered glass? Is it safety glass?
Tempered glass is also referred to as “toughened” or “fully tempered” glass. It is heat-treated safety glass with a minimum surface compression of 10,000 psi or a minimum edge compression of 9,700 psi. The surface of tempered glass is approximately four times stronger than the surface of regular annealed (non-safety) glass of the same thickness.
Glass lid, we have two type glass lids, one is glass with sts rim. another is glass with silicone rim.Normally glass with sts rim, the price is cheaper one, and the glass lid with silicone rim, compare with glass with sts rim, the price is expensive. So the glass with sts rim, it is fit for normally cookware, like stamping cookware. meanwhile, the glass with silicone rim, it is fit for top-grade cookware.
Can You Cut Tempered Glass?
Cutting and shaping glass is the first step in the fabrication process. Tempering is the last. As a result, you cannot cut glass after it’s been tempered.The reason for using this strengthening technique is because tempering decreases the likelihood of glass breaking. More importantly, if by some chance the glass does break, this process ensures that the broken pieces will be relatively small and round, reducing their potential to harm someone nearby. The result is called safety glass.
