I believe that everyone comes into contact with various glass products every day, such as glass cups, glass doors, glass windows, etc. Although we are in constant contact with them, we do not know much about the types and properties of these glasses. However, due to insufficient understanding of glass materials, various problems often occur. We will introduce to you how the heat resistance of the glass wine glass is, and help you to further understand how high temperature the glass can withstand.
1. How about the heat resistance of glass wine glasses
Good quality glass beer mugs are generally made of borosilicate glass.
High borosilicate glass (also known as hard glass) is made of the glass that conducts electricity at high temperature and is heated inside the glass to melt the glass. It is processed by advanced production technology. )×10-6/K, also known as “borosilicate glass 3.3”. It is a special glass material with low expansion rate, high temperature resistance, height, high hardness, high light transmittance and high chemical stability. Because of its excellent performance, it is widely used in solar energy, chemical industry, pharmaceutical packaging, electric light source , craft jewelry and other industries.
The high borosilicate glass has good thermal stability, and the softening temperature is as high as 820℃, which is sufficient for daily use.
Second, how high the temperature can the glass withstand
Ordinary glass will add corresponding impurities according to different needs, the content of silica is relatively low, and the general temperature resistance is 600 degrees.
Heat resistance of other glass products
The silica content of quartz glass reaches more than 99.5%, and the heat-resistant temperature reaches more than 1600 degrees.
The uniform heating of tempered glass can be heat-resistant not more than 650 degrees, and the mechanical properties of tempered glass will gradually decrease if it exceeds 388 degrees.
