Oooops. I know better - those long, curved mandrels need to be dipped in Foster Fire bead release - if you ever want to get the bead off in one piece.
So, why did I dip them in something else? Who knows - blonde moment, apparently.
But that goof led to this discovery. Put the bead, mandrel and all, into an ultrasonic cleaner - let it run for 30-50 minutes. The bead slides off!
I had some chipping on some beads - but I think it was 'coz I didn't have the basket in - just tossed them in loose.
Hmmm - if it will get stuck beads off - I wonder what it will do with normal beads?
It bears further experimentation!
