  1. I am a potter of some years and have been working with a Grolleg cone 6 body for the last year or so. I am continually frustrated by bloating. The bisque has been totally fine tuned. The problem is with larger pieces - thrown from 8 to 14 lbs. Is this air trapped in the walls? out gasing? I am firing the schedule from the Cone 6 Glaze guys . . . I am making extra everything for orders to cover the losses. HELP!!


  2. Thanks Johanna. Since I posed the question on this forum I checked with my local ceramics supplier and he said zinc in the glazes was the problem and recommended a couple zinc-free glazes to try. And he was right! So now I can get true black images. I've found two ^06 and two ^6 glazes that work great.

     

     

    Would you share your recipes??

     

    I have been using a ^6 Majolica that has been pitting when refired at a^04.Any information is appreciated.

     

    Thanks, Pam
