How to Make Plate and Bottle Glass

Glass can be found in many forms, but only plate glass and bottle glass are talked here. There are several steps in making glass. First, the materials which are sand, soda, and limestone must be prepared. After that, the materials are put in the furnace. In the furnace, they are mixed then heated at moderate temperature first, after that the heat should be increased gradually. This requires a long heating to make a clear glass. This process produces the molten glass. Next, the molten glass is brought to separate process to make their shape. The first way, the molten glass is poured into a big container, then it is flown through rollers to make it flat. Finally, the flat glass is cut and formed well to be a plate. The second way, the molten glass is poured into a removable mould which has a bottle shape. In this step, air is flown into the mould to maintain the bottle shape of the glass. After that, the bottle glass needs to be cooled until it gets harder. Finally, the mould can be removed and the bottle is formed well.
