While most clays are designed to cure into a hardened, permanent state after they are shaped, some clays are made to stay workable forever — in other words, the clay never dries! Non-drying modeling clay, also called non-dry clay, is a unique material developed for reusability.
If you’re wondering why a crafter would be interested in clay that can’t dry, you’ve come to the right place. Let’s get started on your journey tolearnabout the benefits of non-drying clay anddiscoverthe differences between non-drying, polymer and air-dry clays.
6 Non-Drying Clay Benefits
Check out sixadvantages to using non-drying clay and discover the many reasons why makers love ourSculpey Non-DryTMclay.
1. Non-Drying Clay Won’t Harden or Dry
One of the best qualities about this clay is listed right in its name — non-drying clay will never dry out. You can confidently walk away from your project knowing that the clay will be just as pliable as before when you return.

The Difference Between Non-Drying Modeling Clay and Polymer Clay
AtSculpey®, we’re known for our polymer clay. While similarly easy-to-use and workable, non-drying modeling clay is a different material used for a different purpose.
While modeling clay is an oil-based clay that can’t dry out or harden,polymer clayis a polymer polyvinyl chloride (PVC) plastic-based clay that cures with heat. Modeling clay is made to be continuously repurposed for new projects. Its adjustable and reusable qualities make this a popular choice for projects that don’t require a hardened outcome.
If you’re interested in creating long-lasting, usable objects such as jewelry, vases and home decor, we recommend you use polymer clay. Unlike non-drying clay, polymer claycan bake in the ovento a cured, durable finished product.
Is Polymer Clay Non-Drying?
Can polymer clay dry? The answer is both yes and no.Non-drying polymer claycannot dry out from air exposure andremains workable until it’scured in the oven. Once baked, polymer clay will dry and permanently cure to a hardened, fixed state.
How Does Clay Dry?
Different clays dry — or don’t dry — based on the materials used to produce them and air and heat exposure:
- Pottery clay:Water-based ceramics and pottery clays will dry to a leather-hard finish as the water evaporates and harden fully after high-temperature kiln firing.
- Air-dry clay:Our water-basedSculpey Air-DryTMclaydries and hardens on its own, in time with air exposure. There is no baking required.
- Polymer clay:Plastic-based polymer clay cannot air-dry and must bake in an oven to cure. With proper storage, unbaked polymer clay remains workable for years.
- Non-drying modeling clay:Oil-based modeling clays cannot be air-dried or cured. By design, these clays will never dry out.
Who Uses Non-Drying Clay?
A wide range of makers use non-drying clay forfreehand modeling, clay practice, animation and mold making:
- Artists
- Sculptors
- Animators
- Mold makers
- Claymation artists
- FX artists
- Teachers
- Students
- Kids
What Type of Clay Is Best for Kid’s Crafts?
Thebest type of clay for kid’s craftsdepends on the desired learning experience and end result for the project.
- Bakeable clay:If kids want to keep a durable, permanently hardened project, use ourSculpey Bake Shop®oven-bake polymer clays.
- No oven, no problem:For a cured project that needs no oven, useSculpey Air-DryTMClay. This no-bake clay is ideal for young clayers and classroom settings.
- Tactile experience:If the goal is providing a hands-on learning experience for kids to squish and shape clay, ourSculpey Non-DryTMModeling Clayis a reusable, cost-effective choice.
Non-Dry vs. Air-Dry Clay
While modeling clay never cures,polymer and air-dry clayscan harden and are commonly used for craft projects. Non-dry polymer clay cures in an oven, while air-dry clay requires no baking to dry.
Depending on the strength and finish desired in your finished project, before you select your clay type consider these possible disadvantages of air-dry clay:
- Durability:Air-dry clay does fully cure, but not to the strength level of baked polymer clay. For wearable jewelry and usable pieces, polymer clay is more durable.
- Working time:Young children may get distracted and walk away from a craft before it’s finished, resulting in the clay drying before it’s fully shaped.
- Hardness:Cured air-dry clay has a slightly spongey feel, while baked polymer clay has a harder finish.
