This lampwork glass bead is made by me in my small studio. The base of the bead is dark ivory. Aqua twisties have been laid on the base as well as silvered ivory stringer. That was melted into the base and then the bead was encased with clear glass.
The bead size is 20mm by 26mm. The mandrel size used is 3/32". It has been properly annealed in my Evenheat Kiln and then cleaned and inspected.
