A type of modeling clay that uses a polymer polyvinylchloride (PVC), polymer clay is called polymer clay. Although it doesn't contain clay minerals, it is just as flexible and easy to use 'if not more so'. After you have molded it to your liking, you can bake it. The clay doesn't shrink after being baked. It just hardens. Polymer clay can be enjoyed with children as long as the adults are able to handle the curing process. You can take your polymer clay home and make it into something that you can keep. To learn more buy a copy.........
