Fused and kiln-formed glass sculpture. Glass fusing is the joining together of pieces of glass at high temperature, usually in a kiln. [1] [2] This is usually done roughly between 700 °C (1,292 °F) and 820 °C (1,510 °F), [3] [4] and can range from tack fusing at lower temperatures, in which separate pieces of glass stick together but still retain their individual shapes, [5] to full fusing ...
Vycor is the brand name of Corning's high-silica, high-temperature glass. It provides very high thermal shock resistance. Vycor is approximately 96% silica and 4% boron trioxide, but unlike pure fused silica, it can be readily manufactured in a variety of shapes. [citation needed] Vycor can be subject to prolonged usage at 900 °C. [1]
Fused quartz is prone to phosphorescence and "solarisation" (purplish discoloration) under intense UV illumination, as is often seen in flashtubes. "UV grade" synthetic fused silica (sold under various tradenames including "HPFS", "Spectrosil", and "Suprasil") has a very low metallic impurity content making it transparent deeper into the ...
Higgins Glass, fused and slumped ashtray and bowl Fused glass piece with dichroic glass highlights. Warm glass or kiln-formed glass is the working of glass, usually for artistic purposes, by heating it in a kiln. The processes used depend on the temperature reached and range from fusing and slumping to casting.
Since devitrification can change the COE somewhat, and devitrified glass tends to be somewhat harder to melt again, there is the possibility of this technique resulting in a less stable piece, however it has also been used effectively with full-fused pieces with no apparent problems. Applying devit spray and refiring can also be effective.
The most important characteristic of porcelain enamel, from an industrial perspective, is its resistance to corrosion. [3] Mild steel is used in almost every industry and a huge array of products; porcelain enamel is a very economic way of protecting this, and other chemically vulnerable materials, from corrosion.
