Hello all....found this Saturday.....I believe to be obsidian....would have been nice to find a point made out of this material...to my knowledge this is a rare find in my area of nw tn....but could be wrong....in the house this appears to be black....but when I found this in sunlight it had some greenish hues to it in several places....thoughts would be appreciated for those with strong geology knowledge

That would be slag from an ore of some kind. I find that all the time in my creeks.. It is mostly black, but there could be blues and greens mixed in. I've found several pieces that have a purple translucency when held up to light."The education of a man is never completed until he dies." Robert E. Lee
