So I was just wondering if this is true...or does it have more to do with the clear glass you use for encasing. Kuglar, vetro, lauscha etc....

Dawn - I just went back to the begining of this thread - forgot how absolutely beautiful you beads are. Man oh man are they pretty, and so perfect. Wowzers !!
Hi Laurie,
Thanks so much for the compliments on my beads!
I haven't heard about encased raku cracking eventually, nor have I had it happen to me. If you're encasing "pure" raku, you should use a clear that has a compatible coe. (Karla uses Kugler) All of the beads where I use frit or stringer, and then encase in clear, were encased with either Lauscha or Vetrofond. Also, I always pop them in the kiln while they still have a good glow.
This is just a guess, but maybe the people who have cracking problems are waiting too long, trying to see the colors develope, before putting the bead in the kiln. I wouldn't worry too much about the cracking rumor.
