Sculpey® clay can sit out for months before baking. So, if youre someone who likes to take long breaks during projects, youll enjoy the capabilities of polymer clay. Polymer clay is oil-based and maintains its moisture, which also keeps it malleable.

Do You Need to Bake Modeling Clay?

Sculpey® offers modeling clay products that are perfect for school projects, claymations and other freehand sculpting activities. What makes modeling clay unique is that you can enjoy crafting without having to bake your pieces. We have two types of modeling clay, each with its own distinct qualities:

Our Air-Dry™ Modeling Clay hardens at room temperature within 24 hours. It retains its shape after drying, allowing for plenty of creative and colorful marker scribbles afterward. Since theres no baking required, Air-Dry™ Modeling Clay is a suitable choice if youre working with large groups of young crafters.

While this modeling clay dries on its own, you can speed up the process by putting it in the oven. Use low temperatures — 200 degrees F or less — and leave it in for the appropriate amount of time. You should leave thinner pieces in for a minimum of 20 minutes. Thicker pieces can stay in for longer, but you should check them frequently.

Non-Dry™ Modeling Clay stands out from our other clay products due to its reusability. This modeling clay remains soft and pliable, meaning you can use it for many crafting projects to come. It shines in arts and crafts that require more flexibility, such as animation. As with Air-Dry™ Modeling Clay, no baking is necessary to enjoy our non-harden modeling clay.
