Can I add cornstarch to polymer clay?

While cornstarch is a common kitchen ingredient, it is not recommended to add cornstarch to polymer clay. Adding cornstarch to polymer clay can have unintended and negative effects on the texture, consistency, and overall quality of the clay.

Texture and Consistency

Adding cornstarch to polymer clay can lead to issues:

  • The cornstarch may create a gritty texture, making the clay uneven and difficult to work with.
  • Excessive cornstarch can affect the ability of the clay to hold its shape and details.
  • Clay with added cornstarch may become crumbly or prone to cracking during baking.

Proper Conditioning

To achieve the desired texture and workability of polymer clay, it’s best to focus on proper conditioning techniques:

  • Condition the clay by kneading and manipulating it until it becomes soft, pliable, and free of air bubbles.
  • Store your clay properly to maintain its moisture content and prevent drying out.
  • Use appropriate additives, such as clay softeners or conditioners, specifically designed for use with polymer clay.

Experimentation and Alternatives

If you want to experiment with different textures or effects on your polymer clay creations, consider using approved additives and techniques:

  • Explore texture sheets, stamps, or tools to create patterns and designs on the surface of the clay.
  • Use mica powders or other compatible products to achieve desired finishes and effects.

By focusing on proper conditioning and using approved techniques, you can achieve high-quality results and create beautifully crafted polymer clay projects.
