Glass Making Process

There are three steps in the glass making process. First, we have to collect some materials such as sand, limestone, and soda. Then, put the materials in the furnace which have thousands celsius degree temperatures. In the furnace, those materials will be melted and mixed. After that, to make a plate glass, pour the mixture into roller pins, let the roller pins pressed it, cool it down, and get the thin flat glass. To make a bottle glass, pour the mixture into a removable mould, blow by air, cool it down, remove the mould, and get the bottle shaped glass.
