Thanks all for the plaster to vermiculite ratios. When I sent the request out I was unaware of the discussion going on about the safety of vermiculite. I hope I didn't confuse the issue. My plans are for my Studio in Art students to pay a great deal of attention to the Modigliani sculptures currently on exhibit here in Buffalo (http://www.whoismodi.com).It's a great exhibit and would recomend it to everyone. Of course coming here to Buffalo in Dec. and January would provide the extra benefit of experiencing our winter.
