Flat glass is made from silicate raw materials, which are melted into a liquid in a high-temperature furnace at 1300 degrees Celsius, and then formed by flowing through the surface of tin water, commonly known as float glass

Float glass is a transparent, colorless flat glass that is created by mixing certain raw ingredients, such as dolomite, quartz sandstone powder, sea sand, and soda ash, and then melting them at a high temperature in a furnace. The glass liquid then continuously flows out of the tank to float on the liquid metal surface. It is applied evenly on a glass strip, burned to polish it, allowed to cool and solidify, extracted from the metal liquid, and finally annealed and cut. The glass surface has extremely little optical distortion, a highly uniform thickness, and a notably smooth and flat appearance. Float glass can be classified as exceptional, first-class, or qualified depending on how good it looks.

A liquid tin surface with a specific gravity higher than the glass liquid is poured with molten glass liquid to create the premium flat glass known as "float glass."
This process method spreads the glass liquid on the surface of the tin liquid, making a homogeneous glass strip, by using the surface tension, gravity, and mechanical pulling force of glass. High flatness, good transparency, lack of water ripple, compact construction, hefty weight, and ease of cutting are some of the benefits of float glass. Because of these qualities, float glass is highly advantageous when used to produce mirrors, automotive glass, curtain walls, furniture, electronic equipment, etc.

Float glass is very smoothly and flat. High quality float glass has almost no impurities, scratches, or tin dots, and can be used for deep processing glass, such as laminated glass, tempered glass, and insulated glass. This is a raw material that is essential for the glass deep processing industry .

Float glass finds widespread application in many applications such as colored glass, float silver mirror, float glass/scanner level, float glass/coating level, float glass/mirror level, and float glass/automotive windshield level.
Among them, ultra white float glass has a broad market potential and a wide range of applications. It is primarily used in the fields of solar photovoltaic curtain walls, high-end buildings, high-end glass processing, high-end glass furniture, decorative glass, lamp glass, imitation crystal products, precision electronics industry, special buildings, etc.

Because of the excellent consistency of thickness, float glass also has relatively strong transparency in its products. It is quite smooth after tin treatment, and surface tension causes it to produce a glass with a reasonably smooth surface, good flatness, and great optical performance. This float glass offers excellent purity, brightness, transparency, and bright interior light, making it a particularly good decorative glass. It is also one of the most commonly used building materials, and it performs well in a wide field of vision. It is the greatest material to use for windows and doors, and it lets in natural light. 

Production process. Float glass is produced using the float process, which involves pouring molten glass raw materials onto a metal liquid surface (usually tin liquid), then unfolding the glass on the liquid surface and gradually cooling and solidifying to form a flat surface; Flat glass is usually manufactured through mechanical pressing or molding, which is relatively simple and usually involves stretching and forming the glass at high temperatures, and processing it through processes such as leveling and annealing.

What is the difference of Float glass and Flat glass ?

Performance characteristics. Float glass has better optical and mechanical properties due to its high flatness and transparency, such as higher compressive and bending strength; The surface of flat glass is relatively rough, with slightly lower transparency, but it has higher strength, especially after tempering, and also has good durability. thirteen

Usage scenario. Float glass is commonly used in situations that require high transparency and excellent optical performance, such as the exterior walls and windows of high-end buildings; Flat glass is more suitable for applications that require high strength and durability, such as large-area glass curtain walls and furniture production
