OMG, no, no, not at all! Sorry. I see how you thought that now. I am interested in the heat treatment of lithic materials as that was a popular practice in prehistoric Oklahoma. It changes the character of the stone and the appearance. And it does make it more workable, should you desire to try a little knapping. I don't see a whole lot of research published on that, but to me it's a fascinating subject. I did not mean to imply you made that up yourself. It would be cool to see how that material responds to heat treatment, though.
