Clear float glass, also known as soda lime glass, is a type of flat glass that is commonly used in construction, automotive, and other industries. It is made by melting a mixture of silica sand, soda ash, and limestone in a furnace until it becomes molten. The molten glass is then poured onto a bed of molten tin, which forms a flat and smooth surface. The glass is allowed to cool and solidify on the tin, which results in a uniform thickness and a flat and smooth surface.
Soda lime glass is named after the two main ingredients used in its production: soda (sodium carbonate) and lime (calcium oxide). The soda is added to the mixture to reduce the melting temperature of the silica sand, while the lime helps to stabilize the mixture and improve its workability.
Clear float glass has a high level of transparency and clarity, which makes it ideal for applications where optical quality is essential, such as windows, mirrors, and display screens. It also has excellent thermal insulation properties and can be coated with various coatings to enhance its performance, such as low-emissivity coatings that improve energy efficiency.
