What Glass Is A Canning Bottle Made Of?


Some friends who are more concerned about the glass industry may often hear people mentioning the advantages of containers. We often come into contact with various glass containers, but because many people do not know enough about the glass industry, all kinds of questions have arisen around it. In order to help you better understand what material canned glass bottles are, what are the advantages of glass containers, and solve your doubts, I hope it can be helpful.

What glass is the canning bottle made of?

Hard glass (also known as high borosilicate glass): SiO2 (about 80%), sodium borate (12%). High temperature resistance, high pressure, corrosion resistance, high mechanical strength, high expansion coefficient, good thermal conductivity, resistance to temperature differences, operation temperature

Soft glass (also known as ordinary glass): According to the composition, it can be divided into soda-lime glass (SiO2, CaO, Na2O) and potassium glass (SiO2, CaO, K2O, Al2O3, B2O3). In corrosion resistance, hardness, transparency and devitrification In terms of properties, potassium glass is better than soda glass, but it is inferior in thermal stability. It has low softening temperature, strong alkali resistance, and is not easy to devitrify. It is suitable for lamp flame processing. Directly heated instruments, such as burettes, pipettes, graduated cylinders, etc., can be sealed with Pt wire because the expansion coefficient is close to Pt.
