What kinds of ingredients are the glass?

Answer:

Is usually made of sand, sodium carbonate and calcium carbonate eutectic is prepared; also available mixture of sodium sulfate and sodium carbonate to replace carbon melting. Some other glass such as potassium glass, is a relatively high temperature, hard and chemical resistance of glass in molten glass with potassium carbonate to replace sodium or potassium sulfate prepared, mainly used in chemical container manufacturing laboratory commonly used.
Flint glass is a high density and high refractive index glass. It can be produced by lead instead of calcium in sodium glass in molten glass. It is suitable for making optical glass and carved glass products. The coefficient of thermal expansion of hard glass is very high
