Cast Glass
Casting refers to a variety of ways of forming glass by pouring molten glass into a mold.

Coldworking
The generic name refers to a wide variety of techniques used to form glass sculpture without heat. Coldworking as a skill is completely different from hot glass furnace work and involves such techniques as grinding, sawing, carving, etching, cutting, laminating, or polishing.

Flameworking
This technique is used to form small objects or decorated beads from colored rods of glass that, when heated over a flame, become soft and can be manipulated into desired shapes. Formerly, the source of the flame was an oil or paraffin lamp used in conjunction with foot-powered bellows; today, gas-fueled torches are used. See lampworking.

Fusing
Fusing is one of several ways of joining pieces of glass with heat until they bond.

Hotworking
The generic name refers to a variety of techniques that involve heating glass at high temperatures to manipulate or shape it.

Laminating
Laminating is the process of fusing pieces of glass through the application of clear or colored adhesives.

Lampworking
Lampworking is an older term for any glass-working technique done with the direct flame of a torch. The term “lampwork” derives from the use of a flame from an oil lamp. See flameworking.

Murrines
Murrines are small fused pieces of colored glass, which are melted in such a way that the various colors join together to create patterns and pictures.

Pâte de Verre
This is a process of mixing ground glass with a small amount of paste and forming it in a mold.

Pipeworking
See blown glass.

Plate Glass
Industrial plate glass is sometimes used by glass artists to create unique objects.

Slumping
This technique uses heat and gravity, and sometimes a mold, to form glass.
