Processes to Make a Glass

There are some steps to make a glass. First, sand, soda, and limestone are put and mixed in a furnace, and then they are heated. Then the mixture is divided into 2 paths of process. In the first path, the mixture is cooled and formed by rollers. It becomes plate glass. In the second path, the mixture is put in a removable mould. When the mixture is put, the air is blown into the mould. Then the mixture forms a bottle glass shape in the mould. Then the mould is removed to get the bottle. These are the processes to make a glass.
