West Texas Ryolite.
Well I tried heat treating it several different ways with no success.
Turkey roaster at 450F for 20 hours
In the oven at 500F for 15 hours.
In sand with a fire built over it for 10 or so hours.
Then did some deep searching and it looks like this type Ryolite doesn't like the heat I have to offer.
So I figured if I can't cook it, I'll just hit it harder.

Finally beginning to have a little success working it.
I've got a long way to go, but least they are beginning to look like points... kinda.
