Here are the pics of the Texas mystery flint that llanago sent me. I've seen it before, and chipped it also. It is a nice working flint, fairly common in Texas. Most people just call them Texas Tabs, (formed in a tabular shape) Perdnales flint is another name I believe. The outer skin is a whitish to brown chalky cortex. The solid flint being in the center. Those look like high quality pieces, and if you do chose to tumble some I bet it will really polish nice. The best thing to do, would be to knock off as much of the cortex as you can. You can use a soft hammer, copper would be best, and flake that skin off. Good luck with it, thanks for the pics, Don   |

Thanks, Don, for posting these and the suggestions of what to do with them.
Since most of the rock around here is limestone, I am thinking the outer stuff can be chipped off pretty easily.
I think it will be beautiful polished.
I'm thinking that big, thick piece might make some pretty nice book ends. It's sure heavy and big enough.
We just gotta figure out how to get the junk off and get it smooth and polished. We can cut it with our new saw (after we learn how to use it and practice on some trash rocks).

One thing that might help chip off the limestone would be to get it wet first, some of my rock have the same substance on it and when it is wet it is easier to get off.
