Start with clean hands and work surface. Recommended work surfaces include Cool Tools Clayboard, glass surfaces, disposable foil, or wax paper. For best results, work light colors before dark colors to avoid staining clay. Condition clay by kneading until soft and smooth. When connecting two pieces of clay together, press firmly to ensure they stick together after baking. See baking times below. Do not use microwave oven. Do not exceed the recommended baking temperature or baking time.
Premo! Sculpey bakes to hardness in the oven at 275°F (130°C) for 30 minutes per 1/4" (6 mm) thickness. It requires no painting.
Changing the Consistency of Clay:
Sculpey clays have the unique ability to be made as firm or as soft as you like. To make your clay softer, simply add a few drops of Sculpey Mold Maker™ until desired consistency is reached. To make your clay more firm, roll your clay into a sheet. Sandwich your flat clay between 8-10 sheets of plain white copy paper. Place a weight on top of your clay (a phone book works great) and allow to sit for 1-24 hours, checking periodically.
Home oven temperatures may vary significantly depending on your oven, affecting the baking of your clay. To test the temperature of your oven prior to baking, pinch off a small ball of clay. Shape a disc about a 1/2" in diameter, approximately a 1/4" thick. Fire at appropriate temperature. Remove from oven and check color. Any darkened areas indicate that your oven is too hot. Lower your oven temperature by 10ºF and repeat test.
