Polymer is quite soft when first removed from the oven. It needs to be cooled completely to reach its final hardness. When polyclay is cured correctly your cooled piece will be difficult to break, but if it is thin it might bend easily. It will break or cut cleanly, without a crumbly texture.
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.
Is polymer clay still soft after baking?

Should you paint polymer clay before or after baking?
The most common paint used on polymer clay, generally after baking, (and if the clay is painted– all over which many clayers don’t do, or just little details, or when it’s used for “antiquing” dimensional areas), is acrylic paint, and it’s safe for using directly on polymer clay.
Can you bake polymer clay more than once?
A common question for those new to polymer clay is “Can you bake polymer clay more than once?” The answer is YES! There is no reason you can’t bake a piece of clay as many times as you need to.

What do you do if polymer clay is hard?
In general, the basic procedure is to chop up the clay in tiny bits (with a blade, crumble it up, or use an old thrift store food processor).

Why does my polymer clay break after baking?
