The given process demonstrates the main stages which take place how plate glass and bottle glass are manufactured.
As can be seen from the process, there are three primary stages, starting from collecting raw ingredients, ending with two types of glass products.
To begin with, the procedure begins with the mixing of three raw materials, which are sand, limestone, and soda. After that, the mixture is put into a furnace and heated to a very high temperature of approximately 1700 degrees Celsius. Subsequently, this combination becomes molten glass. At this point, the molten substance flows down a pipe, where it can be divided into two distinct pathways. In the first path, the molten glass is sent to a tank with a valve, and goes through several rollers. These rollers help flatten the glass and form it into wide sheets. As a result, plate glass is made.
Turning to the diagram in more detail, the second path shows that the molten glass is shaped in molds, and compressed air is pumped inside to help form bottle glass. At the final stage, the molded glass is cooled down, and the process ends with completed bottle products.
