America's First Oven-Bake Modeling Clay

Whether you're a teacher looking for a new activity to engage your students or a clayer who wants to make beautiful creations for yourself, Original Sculpey® is the polymer clay product for you! Our easy-to-sculpt formula is America's first oven-bake clay, so you can count on it to bring your wildest creations to life.

Original Sculpey® Baking Process

Before curing your Original Sculpey® oven-bake clay project, set yourself up for success with these professional claying tips:

• Cover and protect your workspace: Unbaked clay may damage furniture and finished surfaces, so make sure your work area is covered. We recommend working on the Sculpey Tools™ Oven-Safe Work Mat, ceramic tile, wax paper, metal baking sheet, or aluminum foil.
• Condition the clay for durability: Skipping the conditioning process can result in a weakened finished product and increase the risk of cracks, imperfections or breaking over time. Before diving into clay shaping, first condition the clay with our Sculpey Tools™ Clay Conditioning Machine.
• Establish a consistent clay thickness: Cracking can occur during baking if the project has areas of clay that are too thick. We recommend “bulking out” denser projects with an aluminum foil core and adding a supportive wire armature inside like a skeletal structure, especially for figures with limbs.
• Test your oven temperature: Many ovens are not calibrated accurately and are hotter than the dial's temperature setting. Use an oven thermometer to determine the correct temperature and adjust as needed. Condition and shape a 1/4 inch, or 6mm, disc of Original Sculpey® clay, then bake the test piece according to package instructions. If the clay has darkened areas after baking, your oven is too hot. Lower the oven temperature by 10 degrees and test again.

Now comes the fun part — it's time to bake the clay!

1. Preheat the oven: Confirm temperature accuracy with an oven thermometer and preheat the oven or toaster oven to 275 °F (130 °C).
2. Place the clay on an oven-safe surface: Transfer the project onto an oven-safe baking surface. For best results, use a piece of glass, ceramic tile or metal baking sheet with our highly recommended silicone Sculpey® Oven-Safe Work Mat. Because paper cannot catch fire at this temperature, you can safely place card stock or parchment paper between your project and the baking surface.
3. Bake the clay: Slide your project on its oven-safe baking surface into the center rack of the preheated oven. Bake at 275 °F (130 °C) for 15 minutes per 1/4 inch, or 6 mm, thickness. For example, a 1/2-inch thick piece of clay should bake for 30 minutes. 
4. Test the results: Let the clay cool, then press the tip of your fingernail into the bottom of the project. The fingernail may leave a slight mark on a fully cured piece, but it should not enter the clay.

Oven-Hardening Clay Baking Tips

Follow these baking tips for best results:

• Always preheat the oven before baking the project.
• Only use a conventional oven or toaster oven, never a microwave.
• Baking should be completed by adults in a well-ventilated area.
• Always bake at the recommended temperature and baking time.
• Raw clay should not touch any surfaces also used for food purposes.

Kids Love Sculpey® Oven-Bake Clay

Since Original Sculpey® is safe and non-toxic, you can let your kids or students have their freedom while they're creating their next clay project. And it doesn't matter how long it takes for creations to take shape because Original Sculpey® clay won't dry out — you can sculpt it all day long, so there are no limits on your creativity. 

Our oven clay formula is flexible and versatile, and it's a breeze to work with. We offer a wide range of quantities on this classic sculpting formula to ensure you have enough for crowded classrooms or ambitious designs.

Choose the Right Size and Customize

If you want to keep your classroom stocked and your kids' imaginations running wild, you can purchase up to 24 pounds of Original Sculpey®. Because our unique formulation doesn't harden, you can be sure that your clay will be soft whenever you're ready to craft. 

Or, if you want to start with small creations, you can order in as little as 1 pound at a time. This smaller size is ideal for sampling each of our color options — granite, terra cotta and white.

Keep in mind that these colors are only the base of your creation because once you've cured your masterpiece in the oven, you can use water-based acrylic paints to customize it. And since our clay is strong, you can even sand, drill or carve your design once it's cured.
