bake sculpey clay oven

Bake at 275°F (130°C) for 15 minutes per 1/4 in (6 mm) thickness. Do not microwave the clay and do not exceed the recommended temperature or baking time.

Baking time scales with thickness: Sculpey III requires 15 minutes per 1/4 in (6 mm). Increase total bake time proportionally for thicker pieces, and always follow the recommended temperature and time—do not microwave or exceed the instructions.

Store Sculpey III in a cool, dry place below 77°F and out of direct sunlight in clay-compatible containers (polypropylene/PP is recommended). Refrigeration or freezing can extend shelf life; extra clay can be stored and reused without drying out.

Sculpey III is marked for ages 8 years and up and is described as great for beginners, general crafters, and parent/child projects.

Common uses include jewelry, DIY home décor, mixed-media projects, and small figurines—the clay is suitable for a wide variety of small craft projects.

Sculpey III remains soft and flexible until you bake it—there’s no set short-term drying period if the clay is kept sealed and stored properly. Stored correctly, oven-bake clays like Sculpey III can have an expected shelf life of a few years, and extra clay can be stored and reused without drying out.
