1x Vintage Frosted Clear Glass Tube Beads 30mm approx. Hand made matte finish furnace wound glass beads in elongated oval tube shape. These translucent beads are not the most refined, but if characterful hand worked beads are what you are after, then these are they. Some of the beads retain traces of iron oxide through their core (black colouring) created as the molten glass was wrapped around a iron mandrel. The hole dimension is approx. 3mm. Diameter of beads varies also, but is approx. 9mm at the widest point.
