Yep - the container say's it's all natural clay. You let it dry over night and you can paint it with watercolour or acrylics. I have neither, but I have a whole easel filled with oils. I made a round disk to dry and test on that.
First time ever using the product, though I've used clay for kiln drying quite a bit. It's quite similar and the learning curve is quick.
I bought the container in the picture at
Michael's for $7.99. I also picked up three plastic tools for an additional $4.99. I'm not able to find a website that shows them.
I plan on painting the disc tomorrow, so hopefully that'll work and I can paint the rest. :3
