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.
