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.
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 ...
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 mass production of glass beads of many varieties is well represented in the context of a Hellenistic glass workshop in Rhodes, where 10,000 beads of 40 different shapes and colours have been found; [12] [13] Rings, pendants, gemstones, amulets, small sculptures were also made with the mould-casting technique. [14]
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.
