What is Float Glass? A Professional Overview by TopoGlass
Float glass, also known as flat glass, is a highly versatile and widely used type of glass that forms the foundation for many other glass products, including laminated glass, tempered glass, and coated glass. At TopoGlass, we specialize in producing high-quality float glass with consistent thickness, superior optical clarity, and excellent surface flatness — ideal for architectural, automotive, and industrial applications.
How Is Float Glass Made?
The float glass manufacturing process involves melting a mixture of silica sand, soda ash, limestone, and other raw materials at temperatures over 1,500°C. The molten glass is then floated on a bath of molten tin to form a perfectly flat and uniform sheet. After annealing in a controlled environment to relieve internal stress, the glass is cut into desired sizes.
This float process, developed in the 1950s, ensures the production of high-precision glass sheets with minimal distortion, making it the gold standard in the glass industry.
