This past weekend I noticed some black pieces of thin film in my yard. At first I just thought they were leaves, but looking closer they were solid black and I think it might have come from my chimney. It was really thin pieces of black stuff which was shiny on one side a matte on the other. Do you know what this is? If I step on a piece, it just disintegrates to dust.
