Glass Making Process

The process of making glass isn't as simple as we think. First, main materials such as sand, soda, and limestone are put in a furnace. Then the mixture materials are divided based on the form we want to make. If we want to make plate glass, then the mixture materials are put in large container that connected to a gutter with rollers. Next, the materials are flown through the gutter and flattened by rollers so it will form a flat shape. If we want to make bottle glass, then the mixture materials are put in removable mould with bottle shape inside. Next, air is used to fill the center of mould so it will form a bottle shape. Finally, after the materials ossified, the mould is removed and bottle shaped glass is formed already.
