How Is Glass Formed In Transparent Glass Bottles?

Sep 08, 2020

The glass of cosmetic glass bottle is made by CO melting sand, sodium carbonate and calcium carbonate; the mixture of sodium sulfate and carbon can also be used to replace sodium carbonate. Some other glasses, such as potassium glass, are more resistant to high temperature, hardness and chemical reaction. They can be made by partially replacing sodium salt with potassium carbonate or potassium sulfate when melting glass. They are mainly used to make chemical containers commonly used in laboratories. Flint glass is a kind of glass with high density and high refractive index. It can be made by replacing calcium in sodium glass with lead in melting glass. It is suitable for making optical glass and carving glass products. Super hard glass has low coefficient of thermal expansion, resistance to sudden cooling and heat, high temperature resistance and chemical corrosion resistance. It can reduce the content of sodium and keep the high content of silicon dioxide when melting glass, and add 12% - 15% boron trioxide. It is mainly used to manufacture advanced chemical reaction vessels.

Various colored glasses can be prepared by adding a small amount of glass colorant when melting glass. Copper (Ⅱ) or chromium oxide (Ⅲ) produces green; cobalt oxide (Ⅱ) produces blue; manganese dioxide produces purple; tin dioxide or calcium fluoride produces milky white; uranium compounds produce yellow green fluorescence; colloidal selenium produces red jade color; Colloidal gold produces red, red purple or blue; cuprous oxide produces red, green or blue; ferrous compound produces green, which is black in large amount; iron (III) compound produces yellow. When making glass, because of the impurity of ferrous in the raw material, the glass is often green. A small amount of manganese dioxide or selenium can be added to make it colorless glass.

Glass is a mixture of different silicates. Ordinary glass, also known as sodium glass, is a mixture of sodium silicate, calcium silicate and excess silica. It is usually made by CO melting sand, sodium carbonate and calcium carbonate; it can also be melted by a mixture of sodium sulfate and carbon instead of sodium carbonate.
