Float glass is a type of glass that is produced by a floating process, characterized by its smooth, flat and distortion-free surface. It is the most commonly used type of glass in modern construction and manufacturing.
The process of creating float glass involves melting a mixture of high-quality raw materials, such as silica sand, soda ash, and limestone, inside a furnace at high temperatures. The molten glass is then poured onto a bath of molten tin, which acts as a flat, horizontal surface. As the glass flows across the tin bath, it spreads out evenly and forms a uniform thickness. The tin bath helps to cool and solidify the glass, creating a smooth, parallel surface on both sides.
Float glass possesses several desirable properties, making it suitable for various applications. Due to its flat and even surface, it can be easily cut, tempered, laminated, or coated as per the specific requirements of the application. It also boasts excellent optical clarity, allowing for high light transmission and minimizing distortions. Moreover, float glass is highly durable, resistant to scratches, corrosion, and chemical damage.
Float glass is widely used in the construction industry for windows, doors, partitions, and glass facades due to its clarity, strength, and thermal insulation properties. It is also a favored choice for automotive applications, such as windshields and side windows. Additionally, it serves as a base material for the production of various value-added glass products, including insulated glass units, mirrors, furniture glass, and solar panels.
