I found a nice out crop of flint last weekend. It was cracked up bad, I was ripping 50lb boulders off a cliff of this stuff but i reduced it all down to solid pieces and after busting up about 500lbs i ended up with two 5 gal buckets and some pieces over 8 inches long. Dose anyone know if this stuff heat treats well? I made a small preform and it was tough, I put it in with a batch of horse creek and cooked it for 8hrs at 500* and it seemed to work better.
It has a odor to it when knapping.. sorta a oil smell. The rock came from middle T.N.
I thought it was black Dover at first but now i am having my doubts.
Any idea's ?

Don't know...but I like it! 8)

I am thinking its Dover with a high petro content.

Jesse...did this come from over by Chattanooga by any chance?
-
nope this stuff was found west of nashville.

I'd say some variety of Fort Payne or St. Louis. Looks like pretty good stuff.

You know Me....I don't know Squat about Knapping or Rock....so I was just wondering since it had a Petrochemical Smell....it it may have been some sort of Shale....... ::)

From what I have been told, that is crude oil impregnated shale. I have also heard it called black Buffalo River. I don't know what the real name is. It can be knapped raw, if you heat it, it has a tendancy to blow up. The grey rip rap that gets put for erosion control has bands of that in it. I watched Claude make 6" Lost Lake out of a chunk that he got off some riprap at Moundville about 5 years ago. It is very bad about frost cracking. The diesel smell goes away after about ten minutes or so. Bill

I don't have a clue Jesse. I do get ahold of some darker type stuff around here sometime's that has that petro smell to it. I'm thinking some kind of shale too..
