Export Glass Float glass in china

Crystalclear Float glass is a sheet of glass made by floating molten glass on a bed of molten metal of a low melting point, typically tin,although lead was used for the process in the past. This method gives the sheet uniform thickness and a very flat surface.

Modern windows are usually made from float glass.[4] Most float glass is soda-lime glass, although relatively minor quantities of specialty borosilicate and flat panel display glass are also produced using the float glass process. The float glass process is also known as the Pilkington process, named after the British glass manufacturer Pilkington, which pioneered the technique in the 1950s at their production site in St Helens, Merseyside.
