Tempered glass is glass that is hardened by heating ordinary glass to a temperature of about 700 * C, then after the glass is heated, the next process is to cool suddenly, by spraying air evenly on both glass surfaces. Now, from this process there are physical changes in the glass which are changes in the compressive and tensile forces on the glass, but visually there is no change.
So, for what purpose can this glass be used? This type of tempered glass is usually found / we can use on doors (door-free doors), glass walls in buildings, glass boundary walls, stairs, escalators, elevators. As for furniture, it is usually used on tables, glass cabinets, and others. In addition, there are some interesting things about tempered glass, the following information :
Tempered glass is very strong, but that doesn't mean it can't be broken. This type of glass is 5x stronger against impact than ordinary glass, it's a different story if the glass is scratched. This type of glass will break with deep scratches, although not immediately. Glass that is scratched will break over time. See if there are cracks in your tempered glass. Small cracks in the glass will slowly but surely spread throughout the glass until they break.
