Found this on a walk with the dogs last night, its deinately some type of quartz/quartzite grainy and tough
as all hell, I managed to knock some flakes off with a big rock. So the question is, Is it knappable and do you want me
bring some to the Classic?

Yep, that's quartzite, and looks like a pretty good grade of it. I like the color, too. You'd be amazed at what James can do with a chunk of that. If you have some big pieces, bring'em on down and we'll destroy it. :)
-
Thanks Steve, I sent James a PM so hopefully he see's it. Don't think I can find much that is bigger than the largest piece in the picture
but will try. I helped myself to this stuff from some drainage ditches they lined with pit run at our new park ;)
-
It's hard to work pieces shaped like that if they're not good-sized enough to knock good spalls from. How big are they?
-
The smaller ones are fist sized or so, I will go clean the ditches out and see about some bigger stuff :)
Its a city park so I will just wear my city coat and no will will have a clue, they will just think I'm a dedicated hard working, overpaid city worker :P
-
Wow, Dana - that looks like some rough stuff. I betcha I could destroy some of it but don't think I'd get anything made..
-
Dana,
I've made some points out of some tough, grainy quartzite. The stuff you've got is grainy, but it looks pretty homogenous and I'll bet with the right tools you could make something out of it. Wooden billets are magic on stuff like that...
-
I just got done abusing myself on a piece of this stuff and it will work, I just don't have the knowledge or the tools
but I do have a big bruise on my leg :) I will try and find some large rocks of it and bring it to Pappy's. Does anyone
have some dogwood billets they can spare or trade. Its the only rock in the area so I might as well try and learn eh :)
-
Just wondering how many of you manly Knappers want to try this lovely rock. I will go tommow and see if I can round up some big pieces of this sweet working rock :)
Best stuff ya ever saw guys, you will most likely be spoiled for life once ya work some Yooperite, hey I just named some rock, kinda catchy ey Yooperite 8)
-
Dana, I actually love working that nasty stuff. It's the only knappable stuff we have in my neck of the woods, too. Some of the old ones could make nice stuff from it. I'll bring some Smoky Mountainite, you bring some yooperite, and we'll mix and match. ;D
-
ill bring some yankeeite!!. ive gotten a fewe decent points from that stuff. mainly by luck. ive got boulders of that stuff that could crush my truck. i also have some very clear white. and occasionaly find crystal quartz. thats the good stuff.
-
Its not going to be a very safe place in the knapping tent with all the dogwood billets swinging :o ;D
I'm working today so I will go over with the city vechile and seen what I can find ;D
-
Went down and found some Yooperite, but its not real big. I need to take a hammer and sample some of the bigger stuff.
Will bring what I can with me to Pappy's
-
i know i have asked this before.so please forgive me..can the quartzite be cooked...thanks john
-
If I remember right I think Hillbilly said that its unaffected by heat other than a color change
-
Some kinds of it are helped out a little by heat, but others aren't. You'll never get it to knap like chert no matter what you do to it. :)
-
Here's some stuff I had laying around from back in my marble making days. I call it quartzite. I don't really know if that's what it is ???
All I know for sure is that it's extremely tough stuff. It comes from over around Jamestown, TN and Dale Hollow lake. It's what all the old time marble makers around here call "flint". I know it's not actually flint, but if you could get a decent point from it. Not only would it be pretty, it would rival ryolite for toughness.
I have several fist to grapefruit sized pieces laying around. I'll gather it up and bring it with me. I might even be able to get a few more pieces too.

Hillbilly,
You ever work rose quartz???
Dana,
What would it take to get you to send me some of that stuff (large piece, in length)

Brian remind me after the classic and I will see what I can find for ya, and all it would take is reimbursement for shipping :)
I need to find a source for this stuff, picking through the city park for it isn't the best option and most of it is small pieces.
Shannon that looks like some good rock :)
-
Shannon, not sure what that is, but it looks more like Florida chert or coral than quartzite. Might be good stuff. Brian, never tried rose quartz, but it would probably knap pretty good. I've came pretty close to buying a chunk of it in a rock shop a couple times just to find out.
-
Brian, Rose quartze knaps real nice. Shannon, that rock does look like Coral ???
-
It might look like it Eddie, but I'm sure it's not. The creeks around Jamestown are loaded with it. It varies from clear/white, blueish/white, blueish/grey, light yellow amd sometimes a nice amber color.
You can literally pull up to any creek and load a truck bed with it there's so much of it. I think it's just a super good grade of quartzite, but I'm not sure ???
-
Ya'll have got me to thinking about this whole coral thing. It seems that almost every point I see made from coral has always reminded me of this "Jamestown" flint. Could it be possible that it is in fact coral? If so...why would it be in and around that area. I could see somewhere like Florida, but the hills of east TN? ??? ??? ???
-
If its Coral yer gonna be a rich man Shannon :) Of course ya had to tell everyone where it is :o
-
I doubt it's coral, probally just a high graed quartz or chert.
Hillbilly, are you going to bring any of that yellow quartz that's behind your house in the creek?
-
Eddie, I'll bring some.
-
If its Coral yer gonna be a rich man Shannon :) Of course ya had to tell everyone where it is :o
Heck if I'm taking a trip across country to dig it up but that is some nice looking rock! Bring some and lets work it at the Classic. Maybe throw some into the heat treating demo and see how it works!
-
Sawflier, I found some chunks similar in IN in the river and took some to a fellow teacher that is a rock hound/knapper. He tells me that it is horn coral from waaaay back when the midwest was covered by the sea. There were fossils on the outside etc and that is how he determined what it was. Not sure if that helps, but he's a reliable source.

I'd say a bumper draggin 3/4 ton truck load ought to be just about right. If you bring me some I'll bring you some coastal plains chert.Ron
-
I've never seen fossils in coral. I have seen it in chert, though.
-
I think its a fine chert. Maybe a little heat at the classic will make it knapp nice. Bring a pickup full and lets find out! ;)
-
Eddie, coral is a fossil itself. There is silicified coral found all through the midwest, but I don't think it's knapping grade?-They use it a lot for jewelry and stuff. The Petrosky stones from Michigan are fossilized coral, and there's similar stuff in West Virginia and a bunch of fossil coral around Louisville, KY. More rockhound than knapper material, though, I think.
-
Boy....you are trying to become a Honorary Yooper aintcha???...... Petoskey stone is a fossilized coral..... the state stone of Michigan and is commonly found along the shores of Lake Michigan and Lake Huron in the United States.
It was formed by the fossilization of ancient coral called hexagonaria...... These corals lived in warm shallow seas that covered Michigan during Devonian time, some 350 million years ago.

Petosky Stone don't knap, I tried :(
