Do not use unbaked clay on unprotected furniture or finished surfaces. Start with clean hands and work surface area. Good work surfaces include wax paper, metal baking sheet, or disposable foil. Knead clay until soft and smooth. For best results, clean your hands in between colors. Shape clay, pressing pieces together firmly. Bake on oven-proof glass or metal surface at 275 °F (130 °C) for 15 minutes per 1/4” (6 mm) thickness. For best baking results, use an oven thermometer. DO NOT USE MICROWAVE OVEN. DO NOT EXCEED THE ABOVE TEMPERATURE OR RECOMMENDED BAKING TIME. Wash hands after use. Baking should be completed by an adult.
