So I thought it might be an option to use this method. (A long shot, I know...)

Years ago I would make beads on a copper wire pulled tight in my glass lathe. 4 ft long. The beads were flame annealed with a fisher burner, which I moved along as they were made. After I had a bunch made and they were cooled down. I would put one end of the strand into a vise and simply stretch the wire, the beads would slide right off. No bead release was used at all.
