From Sand to Glass


Glassmaking process includes three steps. Those are melting materials, shaping the melted materials, and cooling. At the beginning, sand, soda, and limestone are mixed and heated in a furnace, until all materials are melted. Then, the melted materials are divided to different places. The first portion is distributed into a roller and flattened. After the flat materials are cooled, we can take it as plate glass. The second portion is placed to a removable mould to be shaped. As the same time as the materials are being shaped, the mould is blown by cold air. After that, we get bottle glass.
