It is quite complicated process in making glass. First, The tinny crystal like stone, that usually we call sand and the main composition in this process, is mixed with soda and lime stone. Inside the furnace, the mixture is set on the fire in a very high temperature, about 1700oC. The solid mixture will turn out to be liquid dough that run out through a pipe and divided into two branches for the second step, the shaping process.
There are two major shapes of glasses, the plate shape and the bottle shape. For making the bottle glass, the mixture that has been heated is poured into the removable mould. While filling the mixture into the mould, the air is blown in order to get the size and shape that we want to. Afterwards, we let it cooled down.
Other shape, the plate glass, has different way of shaping process. The dough from the first step is run toward a temporary container. From the temporary container the glass dough is formed into the plate glass by sliding it below the roller machine. The pressures from the rollers will make the flat shape of the glass.
The final step is by decorating the formed glasses by coloring or by drawing them for different purposes.
