Wonderful info... Thank you all
I may experiment a little, just to see. Would not have expected 2 bottles of the same brand could be incompatible... Good to know! I have a couple of champagne bottles from a wedding to make into jewelry for the bride and bridesmaids. Will be careful to not mix them together. Actually, one bottle will probably give me plenty of beads.
I did put some fine silver drops on a few wine beads, then I tumble etched them and some of the silver had come off and left small pits. Such a shame. Perhaps I didn't melt them in enough. First time I had ventured into using silver wire. Always so much to learn!
