Got quite a surprise today when I started knapping a piece of flint I recently purchased. I found Gold spec's, not flakes in the various pieces I was flaking off. But according to a site on the internet what I have is Iron Pyrite, since I couldn't put a scratch in it with my knife. So since I was trying to get at least one knapped head from each piece of Flint I concidered this one a scrap piece, since I had all this Gold(ha ha). The feeling was good til the knife test. So, is there any other obsidian that has this same characteristic with the spec's.
