The glass cup is an indispensable item in our daily life. With the development of the economy and the progress of science, the glass industry is also constantly improving. While researching and developing new varieties, it also strengthens the original glass types. The double-layer glass is not easy to burn, easy to clean, leaves tea stains, and is resistant to friction. It is a high-quality product integrating environmental protection and practical application.
Benefits of Double-layer Glass Cup
The main advantage is heat insulation, and there is a vacuum barrier between the two layers. Therefore, it can protect the water temperature of the cup, and heat insulation is not hot—thermal insulation design. There are two layers of glass on the body of the double-layer glass, with a certain space in between. This design can keep the temperature of the liquid in the cup from losing too quickly, and it can also ensure that it will not burn your hands.
Beautiful and practical. Most of the double-layer glasses are made of excellent high borosilicate crystal glass. Therefore, its surface is smooth and comfortable, and its transparency is high. And it has good abrasion resistance and acid corrosion resistance. In addition, it does not leave any peculiar smell, so it is straightforward to clean.
Resistance to temperature changes. When the ordinary glass suddenly encounters boiling water, it cannot withstand the sudden and drastic temperature change and will burst. But the double-layer glass is different, and it is fired through a high-temperature process. It can withstand an instantaneous temperature difference of -20° to 150° and has a strong ability to adapt to changes in temperature. Therefore, it is not prone to chipping.
