The Making of Glass

There are two types of glass, plate glass and bottle glass. The process of making these two kinds of glass doesn’t have a big difference. First, the main ingredients of glass, like sand, soda, and limestone, are put in the furnace. After that, the ingredients are separated into two other processes. In the first process, the ingredients from the furnace are putted in a big special tray, and then it comes out on a roller which will shape it into a plate glass. In the other process, the ingredients are putted in a removable mould that will shape it into a bottle. Air is given to make a whole in the bottle. Finally, it becomes a bottle glass. Now, we know that the finishing process decide what type of glass we can produce.
