Sculpey Clay is a brand of oven-baked clay used to make decorations and figurines. The clay remains soft and malleable until it is cured at high temperatures, at which point it hardens into a slick material with a texture similar to ceramics. You can paint Sculpey Clay as long as you've taken the time to condition the material for adequate adhesion. Prevent eventual flaking by abrading the oven-baked clay. Ensure an attractive, long-lasting finish by applying the proper paint, using the appropriate method.
