High borosilicate glass is a special glass material with low expansion rate, high temperature resistance, high strength and high hardness. Its good performance has been widely recognized by all walks of life in the world, and high borosilicate glass is also loved by people. However, with so many glasses on the market, how to identify high borosilicate glasses?
1. High borosilicate glass has better transparency, thinner body and smoother hand feel. High temperature resistance, quench resistance and heat resistance are the biggest characteristics of high borosilicate glass products.
2. You can put the cup in the refrigerator for 24 hours and take it out to pour 100 degrees of hot water. If it explodes, it must not be borosilicate glass.
3. It can withstand the instantaneous temperature difference of about 150 ℃, and it is safe to hold cold and hot drinks.
4. High borosilicate heat-resistant glass must be used for double-layer glass. The glass with handle is light and thin. High borosilicate glass must be used with a thickness of less than 2mm.
