Float glass process

Definition

The float glass process is a method of manufacturing flat glass, where molten glass is floated on a bed of molten tin to create a smooth and uniform surface. This technique, developed in the 1950s, revolutionized the production of glass for architectural and automotive use, making it easier to produce large panes with high clarity and minimal distortion. It has become the standard in glass manufacturing due to its efficiency and the superior quality of the finished product.
