Iíve repaired beads before and when I chipped one of my favourite beads I thought someone else might benefit from a how-to.
1) Dip mandrel in bead release (same size mandrel bead was originally made on). Carefully put bead on wet mandrel, trying to get as much bead release in the bead hole.
2) Allow to dry thoroughly.
3) Once dry remove any bead release on bead. I used a mandrel to gently scratch most of it off, then a damp cloth to remove the rest. Make sure all finger prints are removed.
4) Put in cold kiln and bring up to your normal garaging temperature. I brought this one up at full speed but if you want to be careful , you can do it over an hour or two.
5) Once the kiln is up to temperature remove bead. I donít have a bead door so I do this with hemostats, first introducing it into the flame, then dunking the end of the mandrel into a jar of water, repeating until I can hold the mandrel.
6) Repair the bead trying not to use too much pressure Ė the bead release will not be as strong as usual. (Iíve repaired beads before without the release breaking but this one did, luckily I was still able to get an ok finish.)
7) Make sure you get good even heat right down to the mandrel and put it back in kiln, anneal as usual.
Because the bead release broke on this bead I wouldnít sell it but itís for me anyway so Iím just glad to have it back in one piece.
