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.
