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 ]
Tin based systems are not the only ones used, although the most popular. Titanium tetrachloride or organo titanates can also be used. In all cases the coating renders the surface of the glass more adhesive to the cold end coating. At the cold end a layer of typically, polyethylene wax, is applied via a water based emulsion.
Low-iron glass is a type of high-clarity glass that is made from silica with very low amounts of iron. This low level of iron removes the greenish-blue tint that can be seen especially on larger and thicker sizes of glass. [1] Low-iron glass is used for aquariums, display cases, some windows, and other applications where clarity is desired. [2]
Artist Lizzo playing a crystal flute once owned by James Madison. A glass flute or crystal flute is a glass instrument briefly popular in the early 19th century. They are an unusual variety of the Western concert flute designed to preserve pitch and tone during temperature change better than the wood and ivory flutes available at the time of their manufacture.
Ptolemaic Egypt had manufactured small glass mirrors backed by lead, tin, or antimony. [4] In the early 10th century, the Persian scientist al-Razi described ways of silvering and gilding in a book on alchemy, [citation needed] but this was not done for the purpose of making mirrors. Tin-coated mirrors were first made in Europe in the

Titanium nitride (TiN; sometimes known as tinite) is an extremely hard ceramic material, often used as a physical vapor deposition (PVD) coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate's surface properties.
Enamel can be used on metal, glass, ceramics, stone, or any material that will withstand the fusing temperature. In technical terms fired enamelware is an integrated layered composite of glass and another material (or more glass). The term "enamel" is most often restricted to work on metal, which is the subject of this article.
