Aurora Pottery | Air Dry Sculpting Clay, WED Modeling Clay (25 Pounds)

I used this to teach elementary age children about clay because I did not have a kiln available. It must be made clear that they can paint it but they cannot put liquids in it or it will revert back to muddy clay. They also cannot put it in the oven or microwave to "fire" it. It may destroy the microwave oven. I don't remember seeing any warnings about toxic fumes if heated in an oven, but previous experience with similar product showed that this is a possibility so don't heat it at all.
