Re: Ethiopian Opal (Welo)
One thought, when I took an opal class at Wm Holland, Joe DePetro had concocted a resin mix that he would soak the opal in for a few hours then heat it (low maybe 140 to 160 not sure) You may be able to use opticon. In any case, I believe he got the resin from Kingsley North.
I'll look for the info but can't promise I'll find it. KOR John
