Glass making process

Glass are formed into many shapes , for example bottle glass and plate glass. The process of making glass bottle and plate is not simple. There are several steps in the process of making. First, the principal raw material to produce glass, such as sand, soda and limestone are mixed and continuously fed into a furnace which is heated to an extremely high temperature. Then the molten glass emerges from the furnace to branch pipe for two different process. For the plate glass, the molten glass is poured into a large tray connected with rollers that form it into plate shape. For the bottle glass, molten glass is poured into a removable mould and compressed air is used to produce the final shape. Finally, the mould is cooled and bottle glass can be removed from it.
