It is the process in which glass objects are cast by directing molten glass into a mould where it solidifies.
It is formed by a variety of processes such as kiln casting or casting into sand, graphite or metal moulds.
Body Wrap
A body wrap is a single thread of glass that is applied to the outside of a vessel. It is very difficult to put one of these on and have it line up properly.
Etching
Etched glassware are designs that have been cut into the surface by the corrosive action of an acid. An etched-glass surface may be either rough, frosted, satiny smooth or translucent.
Crackle effect
This is made by gathering molten glass and blowing it into a small bulb, then dunking it quickly into cold water. This cracks the surface of the glass, which can then be reheated and blown larger to melt the sharp edges and widen crackle effect.
Festooning
A method where the glass piece is body wrapped, and then pulled from one end to give a very floral or natural effect
Graal Method
This method requires two to four people working in concert with molten glass as layers are carved, shaped, encased in clear glass and added to even more layers.
Incalmo
The glass artist blows two separate bubbles of glass, opens them and joins them together to form a single bubble. It is a difficult operation because the two open lips must be exactly the same size to join properly.
Pezzato
The item is covered with an interwoven of square shapes of various varieties, made by putting sections of flattened canes one next to the other on a metal plate, and afterward getting them on a dismal parison, smoothing them on a marver, and swelling the parison to the ideal shape and size.
Murrine
Using the Filigrana Method, the canes are cut down into small bits, and can be rolled up onto the molten glass.
This color technique offers the glassblower an opportunity to apply imagery and words directly to the surface of the glass.
Filigrana
Canes are created by combining, pulling and shaping several molten glass bits into long rods of cane. A single glass cane can be pulled up to a hundred feet.
