Thanks Paul! I spent a whole year in solitude with nothing but rocks, antler, and leather to keep me company. Somehow, after the smoke cleared and I crawled out of my cave into the daylight, I could actually make stuff out of sharp rocks!
Now I'm learning that heat makes some rocks better! My rock oven has been working around the clock and non-stop for about a month now... heehee.
