The production of glass

The production of glass has several steps. First, sand, soda, and limestone are mixed and heated in a furnace. Then the result is divided to two places. In the first place, the mixture is flattened by rollers then cooled to get a solid form. The result in the first place is plate glass. In the second place, the mixture is poured into a removable mould and blown by air, so in the result the mixture forms a bottle’s shape. Then the bottle glass is cooled and the mould is removed, so the bottle glass can be taken.
