Your Polymer Clay Creation Is Still Soft After Baking

If you take your clay out of the oven and find it’s still soft, it could be one of two reasons: the temperature was too low, or it wasn’t baked long enough. Test the accuracy of your oven with an independent thermometer and give the piece another baking cycle.

Is polymer clay still flexible after baking?

Polymer clay is not like regular earthen clay that cures rock hard. Polymer clay, like Premo Sculpey for example, remain flexible when baked, especially when thin.

How do you know when polymer clay is done baking?

Bake for 15 minutes per quarter inch of thickness. For example, a piece of 1/2″ thickness should be cured for 30 minutes. To test the curing, try pressing the tip of your fingernail into the bottom of your piece after it has cooled; it will leave a mark but will not actually enter the clay.

How do you harden polymer clay that is too soft?

Place the polymer clay in the freezer for approximately 10 minutes before you start working with it. The clay will stay cold if you keep it in a bag of ice. Then, whenever the clay begins to soften again, set it on the ice bag for a few minutes before continuing to work with it.

Why is my polymer clay cracking?

Cracking is almost always caused by insufficient curing or by baking a sculpture with uneven thicknesses throughout. To ensure you have a consistent thickness in your piece, we recommend “bulking out” with foil or creating an armature from Super Sculpey UltraLight™.
