Question: How Do I Know My Polymer Clay Is Baked

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.

What does polymer clay feel like after baking?

Why is my polymer clay still soft after baking?

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.

Can you harden polymer clay with a hair dryer?

If the clay is a polymer clay though, only heat will harden it (and it can never “dry” because there’s no water in it—it’s oil-based and must cure to harden). A hair dryer could perhaps be used but the temp would need to be controlled (too high and polymer clay could scorch/burn, too low and curing would take forever).
