Could someone point me to a place I could purchase coarse vermiculite? (Vancouver or lower mainland area would be best.) Many thanks.
Just beware with vermiculite because Canada and China (and whoever else) still manufacture asbestos. Some vermiculite contains amounts of asbestos in it, so just verify that it doesn't contain, and you will be right. : ) I know this because that is the industry I work in over here in Oz. Ed
