Products made of tempered glass are becoming increasingly common in our daily lives, not limited to doors and windows. Nowadays, many of the furniture we use are made of tempered glass, such as coffee tables, dining tables, and so on. Although it is called tempered glass, it still belongs to the category of glass and is relatively easy to break. Therefore, in the process of using tempered glass, we also need to ensure that it is fully maintained. Next, we will introduce the points to pay attention to when using tempered glass.

1. Pay attention to maintaining the corners of tempered glass

If there is damage at the corners of tempered glass, the risk of glass self explosion increases exponentially. Because the stress points of tempered glass are all concentrated at the corners, maintenance at the corners is particularly important. If tempered glass with damaged corners cannot be treated, caution must be exercised during use.

2. Prevent tempered glass from being under pressure for a long time

For the sake of indoor aesthetics, many families choose to use tempered glass as a tabletop for dining tables and coffee tables. Generally, tempered glass can withstand pressure between 70mpa and 100mpa, and this pressure multiplied by the area of force on the glass is the maximum pressure it can withstand. It is recommended not to place heavy objects on the tempered glass tabletop for a long time to prevent the pressure value from reaching the critical point and causing the tempered glass to break.

3. Prevent uneven heating and cooling

If high and low temperatures are applied to both ends of a piece of glass under extreme conditions, 90% of the glass will self destruct. For example, pouring some cold water on a lit incandescent lamp will cause the glass of the incandescent lamp to break. Although this situation may occur very rarely for tempered glass, we still need to be cautious for our safety considerations.

4. Stay away from acidic and alkaline substances

Prevent tempered glass from coming into contact with alkaline substances such as sodium hydroxide (NaOH) and hydrofluoric acid (HF). Glass is essentially silicon dioxide (SiO2), and chemical reactions can occur when these substances come into contact.

5. Stop using sharp or hard objects to strike the edges and corners of glass

Because the stress points of tempered glass are concentrated at the corners, once the corners break, the probability of tempered glass breaking will increase. Therefore, for the safety of home use, do not use sharp or hard objects to strike the corners of tempered glass.
