Float glass

The phrase float glass describes the manufacturing process of flat glass. Molten glass is literally floated on a bed of metal, usually tin. Windows and glass doors are made from float glass. Float glass can be manufactured clear or colored and is one of the less expensive methods of producing flat glass, as previous methods required more space and time. The float manufacturing process was introduced in the 1950s and is currently the most common way of making flat glass.
