How are clear glass bottles glass formed? Let us take a look together.
The glass of the cosmetic clear glass bottles is made by eutectic melting of sand, sodium carbonate and calcium carbonate; it can also be made by using a mixture of sodium sulfate and carbon instead of sodium carbonate. Some other glasses, such as potassium glass, is a kind of glass that is more resistant to high temperature, harder and more chemically resistant. It can be made by using potassium carbonate or potassium sulfate to partially replace sodium salt when melting glass. It is mainly used for manufacturing experiments. Chemical containers commonly used in the laboratory.
Flint glass is a kind of high-density and high-refractive-index glass. It can be made by replacing the calcium in soda glass with lead when melting glass. It is suitable for manufacturing optical glass and engraved glass products. Extra-hard glass has a small thermal expansion coefficient, is resistant to sudden cold and heat, high temperature and chemical corrosion. It can reduce the sodium content and maintain the high content of silicon dioxide when melting the glass. To make it, it needs to add 12% to 15% boron trioxide, so it is mainly used to make higher-level chemical reaction vessels.
Adding a small amount of glass coloring agent when melting glass can produce various colored glasses. Copper (Ⅱ) or chromium oxide (Ⅲ) produces green; cobalt (Ⅱ) produces blue; manganese dioxide produces purple; tin dioxide or calcium fluoride produces milky white; uranium compounds produce yellow-green fluorescence; colloidal selenium produces ruby color; colloidal gold produces red, red-violet or blue; cuprous oxide produces red, green or blue; ferrous compounds produce green, black in large quantities; iron (Ⅲ) compounds produce yellow. When making glass, because the raw material contains impurities of ferrous iron, the glass often becomes greenish. A small amount of manganese dioxide or selenium can be added to make it colorless glass.
Glass is made of a mixture of different silicates. Ordinary glass, also known as soda glass, is a mixture of sodium silicate, calcium silicate and excess silicon dioxide. It is usually made by the eutectic of sand, sodium carbonate and calcium carbonate, which can also be made by fusion of sodium carbonate and carbon instead of sodium carbonate.
