Over baking will cause hardening of the clay, and burning can cause bubbling and cracking. Do not fill the crack with uncured clay and put back into the oven to re-bake. This generally causes the crack to enlarge. The uncured clay does not fuse with the already cured clay.

Then, Do you paint polymer clay before or after baking?

Paints (and the supplies that go with it) are another must have for most polymer clay artists. I prefer acrylic paints and in many cases “heavy body” acrylic paints, but any type of acrylic paint is safe to use directly on polymer clay. You can use acrylic paints before baking OR after baking your clay.

Considering this, How do I know when polymer clay is done baking? Roll a bit of your clay mixture to the same thickness as the piece that you’re baking. Bake your sample. Cut or break when completely cool to examine the interior for crumbling or brittleness. The first hint that you’re finished baking polymer clay is when your kitchen timer dings.

What does polymer clay not stick to?

Some substances, such as glass, do not stick well to clay; if you’re attaching clay to glass, either make sure the clay goes all the way around the piece (so it can‘t come off during use) or bake the clay and then attach the baked piece to the glass with an adhesive.

Can you bake polymer clay twice?

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. In fact, for complex pieces it’s common to bake parts of the piece separately and then assemble and attach them after baking.
