Float glass is a type of flat glass that is made by floating molten glass on top of molten tin. This process creates a smooth, even surface and uniform thickness, making it ideal for windows and other applications. The result is a clear and high-quality glass that is widely used in construction and manufacturing. The float glass process was developed in the 1950s and has since become the standard method for producing flat glass. It is known for its excellent optical clarity and strength, making it suitable for various uses, including mirrors, glass doors, and facades.
