Can I mix different Sculpey clay colors together?

Absolutely. Mixing colors is one of the most fun parts of working with polymer clay. Condition each color thoroughly, then blend them to create your own shade. You can even mix different Sculpey clay types together — just use the highest temperature and longest baking time when combining formulas. 

Can I use molds with polymer clay? 

Yes! Polymer clay molds help you create uniform shapes and intricate details with ease. Dust your mold lightly with water or cornstarch, press in your conditioned clay, and gently remove before baking. 

Do I need a special oven for polymer clay? 

Your standard home oven or toaster oven works perfectly. We recommend using an oven thermometer to ensure accurate temperature during baking. 

Can I sand or drill my polymer clay creation after baking? 

Yes! Once it's baked and cooled, polymer clay can be sanded, drilled, carved and painted. It is incredibly versatile. Start with coarse sandpaper and work up to finer grits for a smooth surface, or drill carefully to add hanging holes for jewelry and ornaments.
