To bake polymer clay, preheat your oven to the manufacturer’s advised temperature (usually 230°F – 275°F). Baking times are typically 15 – 30 minutes for each ¼ inch thickness. Thinner clay needs 15 minutes to cure. When cool, properly baked clay can be marked with a fingernail, but it won’t sink in.
How do you know when 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.

Can air dry clay break easily?
While air-dry epoxy clays harden the best (and fastest)—becoming tough enough to drill holes in it without creating cracks—other air-dry clays can be fragile and prone to cracking. There are a few ways to strengthen air-dry clay and prevent cracks: Use internal armatures when sculpting to help provide strength.
Which is better polymer clay or air dry clay?
As a whole, the main difference between air dry clay and polymer clay is that polymer clay is a type of thermoplastic that hardens once it is baked in a regular oven. Air-dry clay is a clay and glue mixture that air dries. Polymer clay is more durable and water-resistant while air dry clay is cheaper.
Why is my clay crumbling?
