Modeling, shaping and creating with modeling clay is both fun and rewarding. Modeling clay is great for crafting figurines, jewelry, home decor or free-standing sculptures. Trying to figure out which clay to use may not be as fun.
What’s Oven-Bake Clay/Polymer Modeling Clay
Oven-bake clay, also called polymer clay, as its name suggests, is a modeling clay that’ll harden through baking. Oven-bake clay will remain soft at room temperature and harden when baked in an oven. Oven temperature will vary from brand to brand.
Pros & Cons of Oven-Bake Modeling Clay
- Oven-bake clay has a permanent shape after baking
- Oven-bake clay will be waterproof once baked
- Oven-bake clays, once baked and cooled off, can be polished, sanded, drilled, carved, painted with water based acrylic paint or glazed
- Oven-bake clay stays soft until you bake it
- Oven-bake clay remains soft and pliable when stored in a cool place
- Oven-bake clay requires close supervision at all times when baking the clay
- With oven-bake clay, you have to be careful to keep it covered because it picks up every bit of dust in the air
- Most oven-bake clays must be kneaded prior to use
- Many oven-bake clays will stain or damage

What’s Air-Dry Modeling Clay
Air-Dry Clay, also called ADC, is a modeling clay, that as its name suggests, is a modeling clay that air-dries. No heating, no oven – just leave the modeling clay at room temperature and it will begin to harden. Don’t worry, the modeling clay won’t harden while you’re working with it. Air-Dry clay is soft and pliable so you’ll be able to mold and shape it easily into whatever you want. It will completely air-dry overnight.

Which Modeling Clay is Better
Neither is “better” than the other. It just depends on which is better for you and what you like to create! It takes a bit of experimenting though to find the brand of modeling clay that works best for you and your sculpting needs.
Unlike oven-bake clay, where the clay characteristics are generally similar from brand to brand, the characteristics and quality of air-dry clay can vary drastically. Some clays are soft and marshmallow-like, some are stiff. Some are very durable when dried while some actually stay soft when fully cured and are easily dented or scratched. Some air-dry clays are made with a natural stone based formula, some are paper-based, some are even polymer based. Their self-hardening formulas are the main thing they have in common. The quality varies from brand to brand also. The resin and polymer-based air-dry clays are usually the softest clays and easiest to use. However, the soft clays are not very suitable for fine detail sculpting but are very popular for creating clay flowers.
