Stumped...well sorta of stumped. Cone 04 porcelain frit-ware has some chemistry, that I find challenging. I recall Min talking about having to heavily wedge a Plainsman body that had V-gum T plasticizer. The most colloidal plasticizer used in the pottery biz, to impart plasticity into an otherwise non-plastic formula. Works well for plasticity, but it holds water much differently than more common materials like bentonites or ball clays. The exterior of the ball may be correct, but as you wedge more moisture is pushed to the surface. After wedging numerous times: the problem persisted.
