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 ]
The key advantage of this technique as compared to the float glass process is that the pristine surfaces are not touched by molten tin. The technique is used for the production of very thin flat panel display glass by the companies Asahi Glass Co. , Corning , Nippon Electric Glass , [ 1 ] Samsung Corning Precision Materials , and various other ...
A Japanese glass fishing float. Glass floats were used by fishermen in many parts of the world to keep their fishing nets, as well as longlines or droplines, afloat.. Large groups of fishnets strung together, sometimes 50 miles (80 km) long, were set adrift in the ocean and supported near the surface by hollow glass balls or cylinders containing air to give them buoyancy.
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 ...
The thin-glass bottles were probably made in England, Ard added, as the Spanish did not make their own glass. "Onion bottles are free blown using a pontil," Ard said. "Each one is unique, so there ...
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 ...
The author [who?] has even seen crude torches made of wood which can migrate the checks. The resultant product is a form of flat glass which is suitable for lesser quality uses. Due to process instabilities Fourcault process glass can have waves, seeds (small gas bubbles) or stones (undissolved materials). This distorts the image seen through ...
Green and white sea glass. Sea glass are naturally weathered pieces of the anthropogenic glass fragments of typically drinkwares, which often have the appearance of tumbled stones. Sea glass is physically polished and chemically weathered glass found on beaches along bodies of salt water. These weathering processes produce natural frosted glass ...
