Glass is made by melting together several minerals at very high temperatures by sodium and calcium silicate. Silica in the form of sand is the main ingredient and this is combined with soda ash and limestone and melted in a furnace at temperatures of 1700°C. Other materials can be added to produce different colours or properties.
