Porcelain airdry clay rolled out, small-med-large circles/ovals cut out, then molded to a balloon greased with petroleum jelly, tops trimmed and left to dry to form decorative ''pottery'' bowls - small around smaller balloons and larger around larger balloons...have to try this to see if it works!
This air drying clay is referred to as cold porcelain because it dries to resemble real porcelain. But unlike polymer clay, it's non-toxic and does not need to be cooked or cured. A favorite of many artists, cold porcelain allows you to create very intricate pieces as you can add delicate details to your sculpture.
