Way to Make Glass-Task 3-revision

In the making of glass, a very high temperature (over 2300 C) needs to be reached because of the pure silica melting point. This is why additional components are added to simplify the process. In this case, the additional components are soda and limestone. Soda and limestone could lower the melting point temperature to about 1500 C. These components are mixed in a furnace. In the furnace, the mixture is heated until it reaches the melting point temperature. After it is fully mixed and melted, the molten mixture is transferred using a pipe. The pipe has two branches. The first one is used to transfer the molten mixture to a temporary container. Then, this mixture is transferred into the rollers where it is pressed until it forms the shape of plate glass. The second pipe branch transfers the molten mixture into a removable mould. Here, the molten mixture will be shaped into a bottle glass by blowing air into the removable mould until the mixture form the shape that we wanted. The plate and bottle glass have to be reheated to make them solid and hard. The glass is now ready to be used.
