I read this somewhere as well. When I did the lesson last spring, I used perlite which is a volcanic substance and from the research I did seems to be a safer option. It is used for the same purposes as vermiculite, and I was able to buy it at a local nursery for about the same price. Both materials have an MSDS sheet that you can read on the Schundler Company website.

  I thought I heard that vermiculite has high quantities of asbestos fibers and should not be used?

  I have done this and also added coffee grinds from my morning coffee pot. It gives the plaster a stone look and also has little brown flecks that imitate stone imperfections. I then sprayed the sculptures with acrylic spray. Fooled many a parent at the exhibit as they thought the kids carved and polished stone. ---
