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 ...
Dale Chihuly, then the head of the glass program at Rhode Island School of Design, and Ruth Tamura, who ran the glass blowing program at California College of Arts and Crafts (CCAC, now California College of the Arts) applied early in 1971 for a grant from the Union of Independent Colleges of Art to operate a summer workshop in the medium of glass.
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. "Warm glass" is in contrast to the many cold-working glass processes, such as leaded glass.
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.
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.

An additional ring of glass on the opposite side of the disc increases the possible thickness of the disc to more than 0.3 mm. Best mechanical strength is obtained if both sides of the disc are fused to the same type of glass tube and both tubes are under vacuum. The disc seal is of special practical interest because it is a simple method to ...

Glass production of vessels or other glass objects was mainly of two distinct technological traditions, these of core-formed glass and mould-press or cast glass (Grose 1981). Core-formed glass: is the best represented and probably the earliest manufacturing technique applied. First, a core with the bottle’s shape was shaped around a metallic ...
