Borosilicate spacer beads
These borosilicate glass beads have been handmade in the UK. They are donut-shaped and made 'off-mandrel' Shape is non-uniform, part of the handmade appeal of these beads. Hole size is uneven and varies between beads but averages 2-3mm. Beads may show a line where the glass has joined - this is part of the forming process.
These unique beads have been made using odds and ends left on the workbench at the end of a flameworking session and are in effect a way of recycling otherwise unusable glass. Each bead is different, the beads are very tactile and have that special borosilicate look.
