Lampworking
Lampworking is a type of glasswork that uses a gas fueled torch to melt rods and tubes of clear and colored glass. Once in a molten state, the glass is formed by blowing and shaping with tools and hand movements. It is also known as flameworking or torchworking. Lampworking differs from glassblowing in that glassblowing uses a blowpipe to inflate a glass blob known as a gob or gather, whereas lampworking manipulates glass either by the use of tools, gravity, or by blowing directly into the end of a glass tube.
I use lampworking to make large focal beads for some of my jewelry. I’ll form the glass beads on rods in front of the torch then anneal them in a kiln to ensure durability.
