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 ...
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.
Vitreous enamel, also called porcelain enamel, is a material made by fusing powdered glass to a substrate by firing, usually between 750 and 850 °C (1,380 and 1,560 °F). The powder melts, flows, and then hardens to a smooth, durable vitreous coating.
Glass casting is the process in which glass objects are cast by directing molten glass into a mould where it solidifies. The technique has been used since the 15th century BCE in both Ancient Egypt and Mesopotamia. Modern cast glass is formed by a variety of processes such as kiln casting or casting into sand, graphite or metal moulds.
Kiln-formed glass sculpture "United Earth" by Tomasz Urbanowicz. Several of the most common techniques for producing glass art include: blowing, kiln-casting, fusing, slumping, pâté-de-verre, flame-working, hot-sculpting and cold-working. Cold work includes traditional stained glass work as well as other methods of shaping glass at room ...
Frit. A frit is a ceramic composition that has been fused, quenched, and granulated.Frits form an important part of the batches used in compounding enamels and ceramic glazes; the purpose of this pre-fusion is to render any soluble and/or toxic components insoluble by causing them to combine with silica and other added oxides. [1]
In addition, beads can be fused from sheet glass or using ground glass. Modern Ghana has an industry in beads molded from powdered glass. Also in Africa, Kiffa beads are made in Mauritania, historically by women, using powdered glass that the bead maker usually grinds from commercially available glass seed beads and recycled glass.
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.
