DEFINITION of GLASS SKILLS

HOT
Most people are familiar with the image of the glassblower at the furnace manipulating a gob of ‘hot’ glass. It is not difficult to understand why glassblowing is known as the ‘Hot glass ‘ technique with all the heat surrounding this craft.
Temperature of glass approx 1,300°C.

COLD
On the opposite side of the coin is the stained glass artist, who usually works at room temperature fitting together pieces of coloured glass held together by lead came. This craft is commonly known as the ‘Cold Glass’ technique.
Obviously there are other cold working skills e.g. etching and sandblasting.

WARM
In between these two there are the Kiln workers, this is the type of glass work produced in my studio.
They work with glass at temperatures ranging from 590-900+°C.

There are some glass artists who use a combination of all 3 of the above, but you’ll have to use your imagination as they are too many and varied to mention them all here. I will concentrate on the main areas.

THREE MAIN AREAS OF ‘WARM GLASS’

1.FUSING – Joining glass pieces together by melting them in a kiln.

2. SLUMPING – Shaping glass by heating it over or into a mould in
a kiln.

3.CASTING – Using kiln heat to melt glass inside a mould.

There are many variations and interpretations of these definitions, this is just a basic description
