Sculpey Super medium blend was created by combining two clays, namely Super Sculpey and Super Sculpey Firm Grey, which managed to achieve the best characteristics of each clay - the pliability of the Super Sculpey and the firmness of the Super Sculpey Firm Grey. Bake the clay at 130 °C for 15 minutes for every 6 mm of thickness. Don’t bake in a microwave oven! After baking and hardening, finished products can be painted and decorated using acrylic paints.
