Introduction to Float Glass
Float glass is a type of flat glass produced by floating molten glass on a bed of molten metal, typically tin. This process, invented in the 1950s by Sir Alastair Pilkington, revolutionized the glass - making industry. The float glass process results in glass with a very uniform thickness and a perfectly flat surface, which is free from ripples and distortions. Float glass is widely used in various applications, including windows in buildings, automotive glazing, and display cases. Its high optical quality, smooth surface, and relatively low cost make it one of the most popular types of glass in the market.
