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 ...
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.

Annealing is a process of slowly cooling hot glass objects after they have been formed, to relieve residual internal stresses introduced during manufacture. Especially for smaller, simpler objects, annealing may be incidental to the process of manufacture, but in larger or more complex products it commonly demands a special process of annealing in a temperature-controlled kiln known as a lehr.

[68] It has very low thermal expansion and excellent resistance to thermal shock, being able to survive immersion in water while red hot, resists high temperatures (1000–1500 °C) and chemical weathering, and is very ...
