These beads were made by a student of mine she started making these 25 years ago after purchasing a kit from a show.
They are made on a metal tube on a mandrel that is then rolled in layer after layer after layer after layer,,,,, of enamel powder to build up the bead slowly, then murrini is added around the core.
I know there is a word for this but I can't remember it.
Any and all help is appreciated
Thanks in advance.
