Jamesware posted a topic in Clay and Glaze ChemistryDear Ceramic Arts Community members, I have been making plates and bowls with a ceramic press. Surely, all sorts of factors determine whether a piece releases easily from the ceramic press mold after being pressed, but I'd like suggestions from the community about how the clay body contributes to a smooth, non-sticking release. You see, the easier the release, the better the chances the piece doesn't stick, get stressed non-uniformly, and then warp later. I am wondering if there are materials in the clay body I should be avoiding, or adding... Any advice, information or referrals for help would be appreciated. Thank you! James
