The Process of Glass Production

Glass can be found in several form, for example plate formed glass and bottle formed glass. There are some steps in making plate glass and bottle glass. First, some raw materials for glass production such as sand, soda, and limestone are mixed in a furnace which is set in certain temperature. Then the mixture is divided into two different ways, one for plate glass and the other one for bottle glass. In plate glass making process, the mixture is poured into a large tray which is connected with a roller machine. In the roller machine, the mixture is pressed to make the surface of the glass become flat. Finally the plate glass is formed. In the bottle glass making process, the mixture is poured into a removable mould which has a bottle shape on it. After that, the air is given to the mould to make a hollow space in the bottle. Next, the mould is cooled to make the mixture solid. After that, the solid mixture is removed from the mould and finally the bottle glass is formed.
