Simple Glass Manufacturing Procedure

Glasses are made in various forms, such as plate glass and bottle glass. There are three materials that are needed to make a glass: sand, soda, and limestone. First, those materials are put into furnace that will melt them in an extremely high temperature, so that they will be merged in one liquid and viscous mixture. After that, the mixture is flown into a certain channel depending to what type of glass that will be made. To make a plate glass, the mixture is put into a tank with a hole below it. The mixture will be flown through the hole to the rollers which will flatten them into a plate glass with a flat and smooth surface. After the mixture has hardened, the plate glass is made. To make a bottle glass, the mixture is flown into a removable mould with the shape of the desirable bottle. In order to make the hollow space in the bottle, air is pumped in to it so that the mixture will only form the shell of the bottle glass. Finally, after the mixture has hardened, the removable mould can be displaced and the bottle glass is made.
