The glass used in windows is flat glass, also called “float” glass. This term comes from how the glass is made. 90% of glass today is made by this method. The raw materials are proportioned and mix before entering a furnace. The materials are then heated to 1500° Celsius. The molten glass flows out of the furnace and “floated” over a bath of molten tin. The tin and glass do not mix or adhere to each other. Liquid naturally finds its own level, this creates perfectly flat surface. As it continues off of the tin bath it is cooled and then cut to size.
Other Methods for How Glass Is Made
Another common method for making glass is called the rolled glass process. In this method the materials are melted and cooled slightly. The semi-molten glass then sent through a series of rollers and squeezed down to the required thickness. This is also used to make patterned or textured glass.
