I picked up some pulverized limestone today and noticed something different. Its not powder white...its grey. It has the same texture as the white but its dark. Whats this all about? My supplier tried telling me that its "all natural":confused: . Have you ever seen anything like this?

Plenty of views but no posts. Noone has seen this before?

In pelletized form, yes. I have never seen it that way in pulverized form though.
