cone 6 porcelain issues

09 April 2013 - 12:13 PM

I am having problems off and on with a fine textural bubbling just under the surface of fired pieces. Using a Grolleg cone 4-6 porcelain fired with the schedule from Mastering Cone 6 Glazes. Ideas????

grolleg porcelain problem

09 January 2013 - 01:03 PM

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!!
