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.

How do you know when polymer clay is done?

#3: How Do You Know When Polymer Is Done Baking? When polyclay is cured correctly, your cooled piece can be marked when you press a fingernail into it, but your nail won't sink in. It will be difficult to break, but if it is thin it might bend easily.

How Long Do You Bake Polymer Clay?

Should polymer clay bendy after baking?

Polymer clay beads should be bendable if they are baked correctly. Under-baked polymer clay won't be bendable. It will be brittle and easy to break. So if you can bend your beads without them snapping, like the one in the photo, then you're baking polymer clay the right way.

Can you bake Sculpey twice?

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. It's also perfectly fine to attach raw clay to baked clay and bake that.

Test the accuracy of your oven with an independent thermometer and give the piece another baking cycle.

Can polymer clay harden without baking?

You don't need an oven to harden polymer clay if you choose a clay that cures by air-drying. Check the package instructions, because polymer clay brands all have different curing temperatures.

Why is my polymer clay crumbling?

You see, for some reason, some brands and formulations of polymer clay get hard and crumbly if they've been sitting around too long or stored at high temperatures. Some people say it's because the clay is partially cured.

How long does it take for polymer clay to air dry?

Cracking is almost always caused by insufficient curing or by baking a sculpture with uneven thicknesses throughout. To ensure you have a consistent thickness in your piece, we recommend “bulking out” with foil or creating an armature from Super Sculpey UltraLight™.

Do you paint Sculpey before or after baking?

Preparing Sculpey for Painting

Your Sculpey creation is ready to paint after baking, and after the piece has cooled completely. Paint applied while the piece is still warmer than room temperature may not adhere or dry properly, since the paint itself works best within a moderate temperature range.

How do you smooth Sculpey?

If you're trying to smooth it out to remove fingerprints and stuff like that before you bake/boil the sculpey, you can use a little isopropyl alcohol and go over it with a flat sculpting tool. If you're trying to smooth it out after it's been cured, a very fine grit sandpaper is your best bet.
