I've been experimenting with some Georgetown flint from Texas. This material works great when it is worked raw as it is fine grained,
very smooth and flakes easily. I had never seen or worked a slab of this before or heat treated it either. When I've worked it raw, I was not
able to get long and narrow flakes but when I heat treated it that all changed. I was able to get a decent narrow flaking pattern with long
thinning flakes that I like. I heat treated it using the normal procedures and kept it around 500 degrees for a few hours then turned
off the heat. I did learn a lesson though: Anxious to work some, I pulled three slabs up out of the appx 400 degree hot sand and instantly
heard a dreaded sound of small faint crackling pops coming from the rock. Those proved unworkable but the remainder of the batch
worked just fine. There was no color change which was what I expected and the rock took on a nice gloss when flaked. Photos of a knife
that I made and some raw Georgetown.

Here is a link to the "Texas Beyond History" site which has some historical information on Georgetown flint.
