Can polymer clay be cured in microwave?

The traditional method of baking polymer clay involves using a conventional oven, but some crafters wonder if it’s possible to expedite the curing process by using a microwave. While microwave curing is an option, there are important considerations to keep in mind.

Microwave Curing Technique

It is possible to cure small pieces of polymer clay in a microwave, but it requires careful monitoring to prevent overheating or burning. Divide your clay into thin, small sections and place them on a microwave-safe surface.

Temperature Control

Microwave curing can be unpredictable, and there’s a risk of uneven heating or burning. It’s challenging to control the temperature accurately, which can lead to incomplete curing or damaged clay.

Best Practices

If you choose to try microwave curing, follow these guidelines:

  • Use a microwave-safe container or surface to prevent damage to your microwave.
  • Keep a close eye on the clay during microwaving, and use short bursts of low power to prevent overheating.
  • Be prepared for trial and error, as microwave curing may require experimentation to achieve successful results.


Microwave curing can be a risky technique for curing polymer clay due to the challenges of temperature control and even heating. While it is possible for small pieces, the traditional oven method remains the recommended and most reliable approach for achieving consistent and thorough polymer clay curing.
