Peter, I'm neither a lawyer nor a doctor but I would suggest that when you're screening vermiculite, you do it outside and stand upwind. Some of the older vermiculite that was processed contained asbestos. Newer vermiculite is supposed to be asbestos free - just like paint on children's toys from China is supposed to be lead free. Even if the vermiculite is asbestos free, the very fine powder won't do your lungs any great favors. You have a very nice website and espouse a professional approach to your modeling efforts. I'm glad you landed in S. Mike
