Float glass is also known as flat glass. It is made by floating molten glass on a bed of molten tin and then passing it through the temperature-controlled kiln for annealing the glass (annealing lehr). In annealing lehr, float glass cools gradually and comes out with uniform thickness and flat surface. The raw material used to make clear float glass is sand, soda ash, dolomite, limestone and salt cake.
Clear float glasses are highly popular in the construction of architectural exteriors and interiors of the building. Clear float glasses are distortion free and give good and clear vision. Float glasses give the good sparkling surface and brilliant luster. Clear float glasses are also used in shop windows, showcases, mirrors, furniture, tabletops, and automobiles. There are many popular float glass manufacturing companies, which produce glass in varied thickness depending upon the application and usage.
