WHAT IS HIGH GRADE STONE?
Anything you can run a 1/2" or more flake with a pressure flaker.
HEAT TREATING:
Heat treat a few FLAKES of everything you got except HIGH GRADE Raw Stone, Obsidian, Dacite, Basalt, Hornstone, Sonora, Fort Payne, or Rhyolite. Start with flakes and spalls less than 1" thick for 200°F for 24 hours to dry it out. Then raise the temp to 275°F and hold for 4 hours. Let cool down for 12 hours. Chip and compare. If no difference, put back I at 200°F for 1/2 hour, then raise to 275 for 1/2 hour, then raise to 325 for 4 hours.
Let cool down for 12 hours. Chip and compare. If no difference, put back in at 200°F for 1/2 hour, then raise to 275 for 1/2 hour, then raise to 325 for 1/2 hour, the raise to 375 for 4 hours.
Repeat with temp going up 50°F until you reach 600°F or nice chippable stone. Whichever comes first. If no good result, or things blow up, let us know.

I love seeing Kevin. Puts a smile on my face every time without fail
Me too
Thanks for sharing this.
Have a wonderful Beautiful Morning Everyone ☺️🙏
Forget the napping, you should post hour long videos of petting Kevin.
Too easy
I enjoy your craft of napping stone and flint, I too enjoy the commentary, knowledge is power.
RE pockets of crystals - as I understand it, if the little crystals are pointed, it's called druzy and if they're rounded and look like a bunch of grapes, it's called botryoidal
This man Knapps so much I bet his favorite music is soft rock 🤔🤔😁
Rock, yes. Soft, no. I'm a metal head.
Kevin!! 😎🐾🏹
Kevin rocks. Heat treatment works for me good. Although I have some stone that's white and crushes on the edges somewhat. Even after grinding, wonder if you might've come across that. 🤔
Heat treated petrified coral is like that.
Kevin is so precious
Thanks. I'm sure he agrees with you.
Kevin is the channels unofficial mascot
I have some nice Edwards Plateau boulders from Texas. Should I spall it out first or cook the whole rock?
Spall first.
Patrick when you turn the rock to 200 the elements come on and stay on for the entire time the thermostat is below 200. This causes the rock next to the elements to go well over your 400 target as there is no trickle or differential heating on a plain old turkey roaster and that can potlid the rock near elements or in the corners
True. But that's what happens when you heat the rock with fire the old way (uneven heating). Remember, you're not learning the old ways if you're doing it the modern way.
Do you have a video on making your dome pad and great video
I will eventually.
Hi Patrick,I have rock that was heat treated out in the garage for 6 months now from temps 80 to near zero on and off ,before I knap it should I re-heat treat it ,could the rock absorb moister or once it's treated it's fin.
hb
Once it's heat treated it's fine. Temps below 200°F don't affect the stone.
Kevin is very cute！！Did people burn stones under bonfires in the old days?
Yes. But they also heated rock any way they could, including above ground next to the fire.
@@KnapperJackCrafty Great! Thank you very much.Jack！！
I have a problem that I don't know what to do. What do you do with waist you can't work with?
Throw it away. Make sure it goes to the landfill where there is plenty of modern trash that gives it context as modern knapping waste flakes.
cant find no dang turkey roasters in the uk . i suppose a little toaster oven is the closest thing , or a slow cooker
Just use your kitchen oven.
Wood stoves work too. Just make sure you have a good thermostat and watch it closely.
I found out using a turkey roaster I put sand in with my rocks and I put I use high temperature insulation you put in the lid I put it at 175° I leave it on for one day then I turn the heat all the way up my turkey roaster only goes to 450 I put a high temperature thermometer in it and I can get it heated up to 550 I'll leave it at that temperature for 2 days then I just shut it off by having the sand around your rock it keeps it from cooling down too fast
Keep a log of the stone name, location acquired and the temperature heat treated. Number each stone logged then just number the pieces. Less writing. You can use high temp cement to fill the lid upside down. When dry it shouldn’t absorb much water and it will insulate too. Weight is an issue?…mix cement with perlite.
Trouble is, I lose the log books. I eventually find them but in the mean time I create new ones and I end up with too many.
@@KnapperJackCrafty Oh well, It is what it is. I write myself notes all the time then forget the note. I find it when I get back home.
@@robbybobby64 I keep my notes on my phone as much as possible now. At least I know that if I archive them, they are in one place. The problem is I'm usually using my phone for something else or I'm driving when I need to write something down. I'll get it figured out eventually.
Can you do heat treat in a conventional gas oven ?
Yes
I need to treat my Belton stuff to 400 and see what happens... that snapinhalf stuff looks similar to Belton
Yes, some of the darker Belton is similar to this snap-in-half stuff.
Awhh so cute☺️
Would you heat treat Georgetown of knap it raw?
It depends on the quality. Most Georgetown knaps well raw, but if you can't run long flakes on it easily, it should be heated.
You really should consider selling the failed roasts,for flint and steel. Just saying. Cheers
I got plenty of good raw flint and steel flakes.
Do you use sand?
Never
