Handmade Artisan Glass Lampwork Beads
by Ian Williams
Lampworked Beads are handmade beads created by spinning hot glass onto a mandrel over a flame. Each bead is therefore individually created. Each bead has been annealed to prevent thermal shock.
Annealing is a process of slowly cooling glass to relieve internal stresses after the bead was formed. Generally the process is carried out by a kiln. If glass is not annealed, it is likely to crack or shatter when subjected to a small temperature change. This is called thermal shock. |
