I knapped this one from the butterscotch flint river I cooked in my wife's roaster. I halvted it onto a Red Osier shoot that I filed down till it shot perfect bare shaft.
-
Sweet! I love that butterscotch.
-
that looks real good.
cool photograph by the way.
-
Really looks nice with the American flag on the back!
God bless America 😊

Thanks guys. I agree Eddie I like this stuff especially since it's been cooked. I got my last few points pretty thin hopefully not to thin, I dropped one and broke it in two😞 But it seems like it's cooked perfect it's not brittle and strong enough to take a good flake. Thanks le0n pictures all on my phone. Thanks Knotty old glory is kinda special to me and she goes good with my markings too. Hope everyone has a safe and happy 4th of July

Looks like you got it just right. When it cooks too much it is a darker red and crumbles.

And the rockets red glare! >:D
Very nice, especially since you took the chance
of being subject to Mama's wrath.
Now you have something to defend yourself with >:D

I don't know if that's a good idea. It'd be like bear hunting I'd better make a clean shot or I'd just make her really mad. Lol. All kidding aside she puts up with me and that says a lot
-
nice work all around, arra and point
-
i LOVE the color of that point!
-
Thanks Stixnstones, Thanks Phyankord the heat treatment made the color change. It was a butterscotch color and still is if you remove very much material. The thinner pieces the color went all the way through.
-
Nice point.
I just bought a couple of pieces what temp & how long did you cook it ?
-
I put it in wife's turkey roaster with dry sand. Started at 190 on the dial left it there over night, next morning ramped it up 75 degrees every 45 min. till at highest setting 450 let it soak there for about 6 hours turned down to 300 over night turned off in morning left in sand in roaster for 2 days till cool. Make sure sand is dry I always save my cooked sand and keep it dry. I leave it at 200 so long to dry stones without making steam and breaking them. This was flint river and it turns red when it's cooked. If you look at my cooking stone thread there are pictures the first cook was conservative and helped but second cook was more aggressive you can see color difference in pictures. You might want to start conservative and see how it works you can always cook it again more aggressive if it doesn't work but some stone this recipe would be to high of temp. I ruined some Texas flint once. What kind of stone did you buy trapper and is it spalled?
-
Awesome knapping, love how you married it to the shaft.
-
It is spalled I think he said it was knife river he said it came from NC.
-
I don't know how to cook knife river. My advice would be to start out with a conservative cook maybe just a few pieces see how it works. If it needs more temp. and time you can try again, keep track of how you cook it so you know what works. Maybe Zuma or Eddie can help you I don't have a lot of experience, but enough to know some stone can be over cooked and ruined. When it works it's worth it Bjrogg

I have cooked a few batches of Knife River for a friend. He told me it was likely to get too cracky or blow up if it went high, so I cooked it at 400F for 13 hrs. It flaked beautifully.

I think a lot of blowing up is from moisture still in rock. Need to get all moisture out of rock at a temp. below boiling. If moisture in rock makes steam it will "blow up" the Texas flint I ruined didn't really blow up just became very brittle and not strong enough to hold a flake. I've learned since that it requires a lower temp. It is also important for temp to come back down slow but a good amount of sand really helps for the temp changes, just leave it buried in sand till cool
