That was back when they blamed the crucible manufacturers making bad pots, all of them. That didn't last long as the furnaces began to dissolve too. If the Borax comes out, something else has to go in to get similar results- either lithium, nitrates or fluorine. The caking suggests fluorine to me and anyone with an electric kiln is not going to like that at all. At one point Rollin Karg was having troubles with his moly elements and he showed me his formula which contained Calcium Fluoride. I suggested he get it out of there and his problem stopped.

I find the borax/boric acid issue to be interesting. For me, adding Boric acid to a formula often came hand in hand with cords in a lead or soda base. Borax behaved differently which makes me want to examine the variance in volition loss comparing the two materials. It doesn't keep me up nights.
