Test the accuracy of your oven with an independent thermometer and give the piece another baking cycle.
Is polymer clay supposed to be bendy after baking?
Polymer clay is supposed to be flexible if it’s baked properly. It is a plastic after all. Polymer clay beads should be bendable if they are baked correctly. Under-baked polymer clay won’t be bendable.
How do you know 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.
Does polymer clay become hard?
Polymer clay gets harder as it gets older, making it difficult or even impossible to shape and use, especially if the clay has been left uncovered. Yet many don’t realize that even the hardest clay is salvageable. You can use several methods to revitalize the clay, from hand-kneading to adding oils or diluents.
