Re: Sculpey firm problem.
Hello.
Thank you for contacting Polyform Products Company and your interest in our products. It sounds like the Super Sculpey Firm that you purchased is soft because it is fresh clay. The formulation for the Super Sculpey Firm has not changed.
What if the clay I purchased is too soft?
Occasionally, extremely fresh clay is shipped out or the clay has a little too much plasticizer in it and you may encounter a “squishy” bar. Trust us, this is a good thing. You can make clay firmer very easily! Protect your work surface with wax paper or foil. Simply roll the too-soft clay into sheets about 1/4″ thick. Sandwich it between sheets of clean, white paper, such as computer or copy paper. Do not use printed paper as the print will transfer to the clay. Place a sheet of wax paper or foil over the top sheets of paper. Use a book as a weight on top of the papers. Within an hour you will see the surface of the paper looking “oily.” This is plasticizer being “leached out.” Usually this only takes a couple of changes of the paper and the clay is the perfect consistency. Some artists prefer very stiff clay, and they continue the process several times.
Best regards,
