Hey old timers, we've been using a barium/nickal free metal for a long time Lately porc. has been debonding. Opaque and all right down to the metal.. Nothing is sticking to the metal. We cast with a torch and follow the instructions for preparing the metal. Not all the units, but once in awhile. I always had to almost grind off the porc. and opaque to redo the crn. Now this is starting to happen. Obviously there is no bond and I want to know why? Any thoughts?? In my time I've used every thing from high noble to non-p and started before non-p came out and was one of the first to use non-p and I've never seen this. Thx, Dave
