Sculpy is a brand of plas-clay. Cook it at 250º for 10-15 minutes and it is like brittle, hard plastic. It can be sanded, filed and glues well. Get it at Jo-Ann's, Michael's or most arts & crafts stores. Good luck.
Any1 in San Diego know where i can buy it and how much it is??? or just a website where i can get it from?
what are you making with it? Sculpy is good for small things that need to be hard. If you are working and re-working the clay dont bother with sculpy. Use Roma plastacine or even the cheeper Jolly King brand. They come in various hardness and even a sulpher free variety which does not smell bad.
