Heat Treating - The Light Bulb Turned On! (Updated 6-15-2011)
« on: May 17, 2011, 07:12:34 pm »
Wow!  Some rock actually gets STRONGER when heat treated... in addition to being more knappable and more glossy!  Makes me wonder why I didn't start my rock cooking adventure sooner.  It's a whole different ball game now...

I'd heat treat that gray Ryolite. I'd be more fun watching it blow up than beating on it. ;D

Right now I'm trying to figure out what type of stone I was knapping the other night.  I just dumped a bunch of mixed flakes into the turkey roaster and let it cook overnight.  I was able to make a VERY thin edge on the stuff...felt like I was knappin' tempered glass.  It's some sort of dark grey Edwards plateau chert that I heated to 400 degrees.  I'll keep ya posted... ;D

Sounds like some of my students.. It's an experience I never tire of, watching kids have a light bulb moment and say, "Ooohhhh!!??!!!"

If I had some of that KY blue, I wouldn't have to entertain myself with exploding rhyolite ;)

Although I'm somewhat proud of myself for carrying that 100 lb. rock out of there, I keep wondering just why in the hell I did that.
