Hello! Does anybody have experience firing Standard Clay 112 or 182 to cone 06/6? These are the clays that I work with and typically my studio fires to cone 05/5. However, I have recently started working out of home and found a studio nearby that will fire my work, but to cone 06/6. I want to be sure that I like the result before committing to the change.
I have been having a strange issue with my Cone 6 Black Stoneware Clay from Standard (266). It gets these big cracking bubbles upon glaze firing. I bought this clay to marble with Porcelain (Standard 365) because it had a similar shrink rate. The marbled pieces came out SUPER bubbly, really horrible. I thought it was just poor clay preparation on my part because of the mixing of the two. However it has been happening with pots I make solely out of the Black Stoneware. I prepare this clay the same way I do all my other clay bodies and never really have this issue otherwise. Has anyone else had
