If your polymer clay is not hardening properly in the oven, there could be several factors contributing to this issue.
Possible reasons for incomplete polymer clay curing:
- Temperature Inaccuracy: Ensure that your oven temperature is accurate by using an oven thermometer.
- Insufficient Baking Time: Follow the manufacturer’s recommended baking time to ensure thorough curing.
- Thickness: Thicker clay creations may require longer baking times to achieve full hardness.
- Oven Hot Spots: Uneven heating within the oven can lead to uneven curing or underbaking.
Properly preparing your oven, using an oven thermometer, and carefully following baking instructions can help ensure successful polymer clay curing.
