It is no bake clay (even after sitting for over a decade it is still soft and oily, which is why it is covered in dust), I found that out the hard way. The first version melted in the oven.
I've used an air dry clay,that seemed to be an organic clay, to make Rosaries and they actually turned out well. The beads took a couple weeks to dry fully and then I took a paper clip and burnished them with the edge until they took on a shine. I don't remember the brand. It was sold in small blocks at a US chain of hobby stores called Hobby Lobby.
