Jun 10 2014nbsp018332forgive my sand ignorance but am i wrong in thinking that all sand has some amount of silica some more than others yes but i guess the point as stated in the blog link is to find sand with lesser amounts of silica quote i did also find this at the blog link which may be the party pooper for the dg since granite is at least part
