The glass has excellent performance and can be used in many occasions. Painted glass and hot-melt glass can be used for indoor decoration with various styles. If you need to protect personal safety, it is recommended to use tempered glass, laminated glass and other safety glass. When you need to adjust the brightness and protect privacy, Frosted glass and dimming glass should be used. The glass for drinking water uses high borosilicate, which is convenient, safe and durable. Here's how the glass can break.
When hot water enters the glass cup, cracking occurs because the glass expands unevenly after heating. When hot water is poured in, the side walls of the cup are heated and expand, but the side walls of the cup are not heated evenly. Therefore, the inside of the cup will immediately heat up, but the outside will not immediately heat up. The inside will rapidly expand, but the outside will remain unchanged, so there may be external and internal phenomena. Therefore, it is not necessarily that the thicker the glass, the better. Thick cups will break when heated, while thin cups are not fragile, Thin cups can quickly transfer heat from the inside out, so the temperature of the cup will quickly become uniform and the degree of expansion and deformation will also decrease, making it difficult to reach the internal and external temperature of thick glass. In a short period of time, the internal temperature is high and the expansion is rapid, while the external part has not yet expanded, and the external part is compressed by the internal part, making it easy to crack.
When the weather suddenly becomes hot and cold, glass is prone to breakage. These are all due to uneven heating of the glass, which is different from heating. When suddenly cooled, the cup will start to contract on the outside, but the inside has not yet contracted. Therefore, if the inside is squeezed by the outside, the glass will break.
When choosing a glass cup, it can be considered that a high borosilicate double layer glass cup can effectively solve the above problems. It can support an instantaneous temperature difference of -30 to 150 degrees Celsius, and the glass will not break.
