Why is my polymer clay not hardening in the oven?
Polymer clay is a popular crafting material that, when baked in an oven, hardens into a durable and colorful object. However, sometimes the clay may fail to harden properly, leaving it soft and pliable. There are several reasons why this could happen, and addressing these issues can help ensure a successful baking process.
Firstly, the clay may not have been cured properly before baking. Polymer clay needs to be thoroughly dried and cured for at least 24 hours before it is ready to bake. This allows the clay to fully harden and prevents cracking during the baking process. If the clay is still too soft, try drying it for a longer period, or use a faster-curing clay if available.
Secondly, the oven temperature may be too low. Polymer clay requires a specific temperature range to harden properly. Most clay brands recommend baking at 260-280°F (127-143°C) for around 15-30 minutes. If the oven is too cool, the clay may not fully harden, resulting in a soft and pliable object. Make sure your oven is preheated to the correct temperature and that it is calibrated accurately.
Thirdly, the clay may be too thin or too thick. Polymer clay should be at least ⅛ inch (0.32 cm) thick to ensure proper hardening. If the clay is too thin, it may not support its own weight and may warp or melt during baking. On the other hand, if the clay is too thick, it may not harden evenly and may leave soft spots. Try adjusting the thickness of your clay to find the optimal range.
Fourthly, the clay may be too close to other objects in the oven. Polymer clay should be baked in a clean, empty oven with plenty of space around each piece. If the clay is too close to other objects, it may not heat evenly and may leave soft spots or warp. Make sure your clay is spaced far enough apart to allow for even heating.
Lastly, the clay may be contaminated with moisture or other materials. Polymer clay is sensitive to moisture, and any excess moisture can prevent proper hardening. Make sure your hands and workspace are clean and dry before working with the clay. If the clay is contaminated with other materials
