What is the best way to handle softer clays?
Mushy or sticky clay can be leached to remove excess plasticizer before molding. Roll the clay into a thin sheet and place it between sheets of clean typing paper with a heavy book on top. To prevent damaging any surfaces, stack it like this: aluminum foil, typing paper, clay, typing paper, aluminum foil, book. Overnight should be long enough. The longer you leave it, the more plasticizer leaches out of the clay and is absorbed by the paper. Firmer clays such as Fimo mold well. If you add Mix Quick or any other conditioner to Fimo, use it sparingly. In general, no more than one part Mix Quick should be required for four (or more) parts of clay.
