Float glass is a sheet of glass made by floating molten glass on a bed of molten metal of a low melting point, typically tin, [1] although lead was used for the process in the past. [2] This method gives the sheet uniform thickness and a very flat surface. [ 3 ]
Today most glass manufacture has a "hot end" where the products are made. Fourcault is no exception. The action in Fourcault happens "at the draw", or area where the glass is taken from a liquid state into the start of the process needed to make it into flat glass.
Glass container manufacture in the developed world is a mature market business. World demand for flat glass was approximately 52 million tonnes in 2009. [9] The United States, Europe and China account for 75% of demand, with China's consumption having increased from 20% in the early 1990s to 50%. [9]
In hollow glass production (hollow glass), the glass machine below is fed with glass gobs. In flat glass production (float glass), the glass is fed at special wide outlets as a glass ribbon over a so-called float bath of liquid tin (for flat glass without structure : e.g. window glass, car glass) or for flat glass with structure over a profiled ...
In the 1950s, Pilkington Bros., England, developed the float glass process, producing high-quality distortion-free flat sheets of glass by floating on molten tin. [21] Modern multi-story buildings are frequently constructed with curtain walls made almost entirely of glass. [47] Laminated glass has been widely applied to vehicles for windscreens ...
Cylinder blown sheet is a type of hand-blown window glass. It is created with a similar process to broad sheet, but with the use of larger cylinders. In this manufacturing process glass is blown into a cylindrical shape by a glass blower. The ends of the cylinder are cut off and a cut is made down the side of the cylinder.
Plate glass is often used in windows. Fragment of a Roman window glass plate dated to 1st to 4th century CE. Plate glass, flat glass or sheet glass is a type of glass, initially produced in plane form, commonly used for windows, glass doors, transparent walls, and windscreens. For modern architectural and automotive applications, the flat glass ...
If the design is located on the piece, it is authentic sea glass, since artificial glass will typically not have that particular design. [11] Sea glass usually comes from broken glass bottles or other household items, so pieces found on beaches will not be perfectly shaped, unlike artificial sea glass, often sold as beach glass. [11]
