You might be wondering what to bake polymer clay on — and it all depends on the piece. For flat items like frames or objects with flat surfaces, like the bases of figurines or the bottoms of jars or candleholders, a flat surface like a metal baking tray, ceramic tiles or glass will work fine. Make sure to use a parchment paper or aluminum foil to cover ceramic tiles so your items don’t develop an unwanted sheen from touching the ceramic surface you have created. For objects that are round, or for shaped sculptures you want to perfectly preserve, you’ll need to choose another kind of surface. Polyester stuffing, cardboard holders, shaped aluminum foil or the Sculpey® bead baking rack will help your clay items maintain their shapes while baking.
The right temperature to bake polymer clay- When preheating your oven to bake your polymer clay, make sure you consult the directions on the package. They should give you an idea of what temperature to bake which clay and how long to leave it in the oven. In general, our clay lines like Pluffy™, Premo! Sculpey®, Sculpey® III and Sculpey® Soufflé™ bake at 275 degrees Fahrenheit.
Again, your package should give you a good estimate of how long to bake your polymer clay
. The time you’ll need to leave it in the oven depends on the thickness of the unbaked clay. Measure or approximate the depth of the thickest layer of your creation. The directions on your package will tell you the baking time per a specific measurement, such as ¼ inch. For example, you’ll need to put Sculpey® Soufflé™ in the oven for an estimated 30 minutes for every ¼ inch of thickness, while 15 minutes per ¼ inch is recommended for Sculpey® III.To be cured completely and achieve the final level of hardness, you must allow your polymer clay to cool properly.
