The origins of glass go back to Mesopotamia. It was the merchants who traveled through this unique country who noticed that the fine sand after getting into the fire changes its appearance. Today we know that the merit of this is the quartz present in every grain of sand, which, after melting, turns into glass. Although we are used to the fact that glass is transparent, initially only colored glass forms were melted. The process, which was initiated thousands of years ago, today thanks to modern technology, allows for the production of unique tempered glass that accompanies us every day.

What is toughened glass?

ESG or glass tempered this type of glass that has been heat treated. As a result, its resistance to shattering has significantly increased. The appearance of toughened glass does not differ from ordinary glass, which has not been toughened, but its physical properties change. Heated to a temperature of about 660 degrees Celsius, it is stopped and then rapidly cooled. During toughening, compressive stress is created on the glass surface, which affects its hardness and density. The toughening process causes a six-fold increase in the strength of the glass, which breaks down into small pieces after breaking, thus reducing the risk of a life-threatening injury. An extremely important piece of information for people who have not had contact with glass hardened is the fact that it cannot be post-processed. The huge tensions occurring in it, which affect its resistance, would damage it under the influence of grinding or cutting.

 Advantages of toughened glass

The greatest advantage of tempered glass is its versatile use. Perfect as a glass for the kitchen, glass for a shower cubicle, or an additional glass for a mobile phone. High impact resistance, which is much higher than in the case of ordinary glass, makes it perfect as a glazing for balcony enclosures. Currently, toughened glass is considered the safest type of glass in the world.

Tempered glass – factors affecting the price

There are many toughened glasses on the market. The sizes are usually matched to the respective phone model. This is because toughened glass cannot be cut. Their price starts from several dozen zlotys and ends even at one hundred zlotys. Such a large discrepancy is caused by the fact that toughened glass has a different hardness. The harder the glass is, the more protection it provides. On the Mohs scale, a thickness of 9 to 10H is dedicated to mobile phones. The second factor that affects the price is assembly. Most users choose to purchase products that are easy to install. This allows a lot of freedom in terms of replacing the glass with new ones, as well as completely abandoning it. A few years ago, tempered glass ousted screen films from the market, which only protected against delicate scratches.

Tempered glass for the phone – is it needed?

Tucked in trouser pockets, on desks, handbags or backpacks, the phones are susceptible to scratching. In this case, tempered glass for the phone comes to the rescue. By deciding to install it, users can stop worrying about unsightly scratches, as well as the specter of the touch screen breakage. High-class tempered glass protects the surface of the phone against mechanical damage. The tempered glass for the phone should be 9H or 10H thick. This means that the protective layer of the phone can only be scratched with a diamond blade. Tempered glass placed on the screen of a mobile phone should not reduce the sensitivity of the screen. What’s more, they can be cleaned with any agent, without fear that it will affect the technical condition of the cell screen.

Tempered glass for the phone – how to properly put the glass on?

Before installing the tempered glass, clean the screen surface thoroughly. The best cleaning products are polishing cloths for glass and glasses. You can also use popular compressed air for this purpose, which will remove dust particles from its surface. When sticking glass onto the screen, special care should be taken to ensure that there are no voids with air between the glass and the glass, which would quickly lead to the breakage of the protective glass. Despite its hardness, tempered glass does not tolerate a constant change in tension on its surface. When broken, torn off and crushed, it begins to crumble.

Tempered glass accompanies us every day. For safety, almost everyone who has a touch phone places a protective layer made of tempered glass on the main screen. In second place are all kinds of vehicles that allow you to get to work or school. Regardless of whether we use a tram, subway, train, car, scooter, bus or even a motorcycle, all the windows in them are made of tempered glass that does not break, and crumbles into thousands of pieces that do not cause such mutilations, as in the case of ordinary glass.
