Making Glass Procces

There are several steps in making glass. First of all, the main substances such as sand, soda, and limestone are mixed together in the furnace. After all substances are heated at very high temperature, those things become molten glass. Then, molten glass is divided to two processes, depend on the purpose. In the first process, the molten glass is flown through some rollers to be pressed. This step will turn the molten glass into flat shape which is also known as plate glass. In the second process, molten glass will be formed into bottle glass. At the beginning, molten glass is sent into removable mould. In this step, air is also blown into the mould so the bottle glass can be easily formed. After the forming process has already finished, the bottle glass is cooled until it gets harder. Last, the mould can be removed and bottle glass is ready to be used.
