Why do you put cornstarch on polymer clay?

Polymer clay is a versatile and popular medium used by artists and crafters to create a wide range of projects, from intricate jewelry to sculptures and figurines. One technique that has gained attention in the polymer clay community is the use of cornstarch. In this article, we’ll delve into the reasons behind using cornstarch on polymer clay and explore the benefits it can offer to your crafting endeavors.

1. Managing Stickiness

Reducing Stickiness:

Dealing with tacky polymer clay:

Cornstarch is often used as a solution for polymer clay that is too sticky or soft. Applying a thin layer of cornstarch to the surface of the clay can help reduce its stickiness, making it easier to work with and preventing it from adhering to your hands, tools, or work surface.

2. Texture and Detail

Enhancing Texture:

Adding texture and details:

Cornstarch can be used to create unique textures and patterns on polymer clay. By dusting cornstarch onto the clay before pressing it onto textured surfaces, you can achieve intricate designs and enhance the visual appeal of your creations. Cornstarch acts as a release agent, allowing the clay to release easily from the textured surface without distorting the design.

3. Preventing Distortion

Avoiding Distortion:

Maintaining shape and form:

When working with polymer clay, especially delicate or thin pieces, cornstarch can help prevent distortion or stretching of the clay. Dusting cornstarch onto the clay before shaping or handling can reduce the likelihood of stretching or changing the shape unintentionally.

4. Clay Softening

Softening Firm Clay:

Improving pliability:

In some cases, cornstarch can be used to soften polymer clay that has become too firm or stiff. By kneading a small amount of cornstarch into the clay, you can improve its pliability and make it easier to condition and work with.

5. Cleaning and Finishing

Final Touches:

Removing residue and enhancing appearance:

After working with polymer clay, cornstarch can also be used to clean and finish your creations. Dusting cornstarch onto the surface of the clay can help remove fingerprints, smudges, or excess oils, resulting in a cleaner and more polished appearance.


Cornstarch is a versatile tool in the world of polymer clay crafting, offering benefits such as reducing stickiness, enhancing texture, preventing distortion, softening firm clay, and providing a final touch to your creations. Whether you’re looking to improve workability, achieve intricate designs, or ensure a polished finish, cornstarch can be a valuable addition to your polymer clay toolkit. By exploring the various ways to use cornstarch, you can unlock new possibilities and elevate your polymer clay projects to new levels of creativity and craftsmanship.
