Sheet glass is a type of glass that is produced in large, flat sheets. It is typically used for windows, mirrors, and other flat surfaces. There are several synonyms for the term "sheet glass," including float glass, plate glass, and flat glass. Float glass is a type of sheet glass that is made by floating molten glass on a bed of molten metal, resulting in a uniform thickness and high-quality finish. Plate glass is another type of sheet glass that is made by rolling molten glass between two rollers, resulting in a smooth, highly reflective surface. Flat glass is a general term that refers to any type of glass that is produced in flat sheets.
