4mm clear float glass is a type of glass that is made by floating molten glass on a bed of molten metal, typically tin. This process allows the glass to be made with a uniform thickness and smooth surface, which makes it ideal for use in a variety of applications. 4mm is a relatively thin thickness for float glass, and it is commonly used in applications where a thin, transparent material is required, such as in windows, doors, and other types of glazing. It is also often used in the manufacture of mirrors and other reflective products. Clear float glass is made from raw materials such as silica, soda ash, and lime, and it is melted at high temperatures before being cooled and cut to the desired size and shape.
