I think it depends on the cut of the crystal. Briolettes chip really easily,
etc. It's the edges you'd worry about. With PMC we tumbled both fused class and lab created stones that were fired in the silver. I'm sure a crystal would have been fine; I would not have hesitated. My only question is whether a rotory tumbler would be any harder on it than a vibrating tumbler was. A natural crystal (rock) is full of plains and will chip. But I am quite sure the lead that's added to glass to make crystal makes it much stronger. Which is why they can makes such fine, thin stemware.

We were using the vibrating tumblers for work hardening as well, in the PMC
class, though it was an expensive one and may have had another motion besides the vibration. Tina "vj" wrote in message ah - okay, in one of the other groups where they were discussing tumblers, they said that "vibrating tumblers work for polishing, but not for work-hardening". |

Are the crystals you have that chip easily also Swarovski?
You know, one caution about tumbling that I didn't think of before, pertains to ABs. The finishes applied to crystals are just a thin coating. I think those would be easily damaged by tumbling.

A vibrating tumbler polishes much faster than a rotary tumbler. I have a
rotary tumbler and only put the uncapped dichroic glass (fused) & PMC in for 1 hour and it was OK. I don't know about little beads, probably bad news for AB or luster coatings. -- Connie Ryman Cryman Studio www.eclecticbeadery.com "Christina Peterson" wrote in message news:1058986404.354065@prawn...

But I am quite sure the lead that's added to glass to make crystal makes it
much stronger. I have often had Swarovski crystals chip when wire wrapping them. This doesn't happen unless the wire is next to the cystal itself, so I try to put something else, even just a seed bead, next to where the wire wrap will be. But having them chip at all illustrates to me they are more fragile than they appear. I would never try to tumple them with shot.

Hi Carol,
I've been tumbling my chains with crystals with no problems at all. In fact, I just finished tumbling some ....1 of them has crystals and a lampwork bead and the other 2 have crystals and porcelain beads. They were all tumbled for about 21/2 hours. They came out of the tumbler all pretty and sparkly. I don't tumble AB for sure. Cisco I would never try to tumple them with shot. |

wrote: I would think not - the shot would chip/break all the facets in the crystal. Someone correct me if I'm wrong... I tumble almost all of my jewelry as a final finish. If the stones are relatively hard, they get set first and tumbled with everything else. Crystals too. Remember, you're just tumbling. It's a rubber barrel making slow turns, just rolling and rolling. Just like sea glass in the ocean. Only the sand gives the glass a matte finish. The steel gives the metal a shiny finish. I have set faceted gems and tumble polished the finished piece. Why? Because the metal is still flexible from the soldering. After tumbling it's work-hardened and much harder to set stones. Especially if you are bezel setting.

Bezel setting is the simplest form of setting. Get Tim McCreight's book "The Complete Metalsmith". It tells you everything you need to know. You don't even need a class for it. Or, If you're ever in St. Louis, stop by for half an hour and I'll teach you how. Barbara Dream Master www.dreamweaverstudio.com "We've got two lives, one we're given, the other one we make."
