Knappability, other than tallahatta, I don't think there are any quartzites that are easier to knapp. Locally, North Ga quartzite, always fits when knapping. Good job for producing something from it.
I don't have any cherts or flints in my area so I've tried to find other rocks that fracture conchoidally. There is quartz and other medium to fine grained rocks that are red and green that fracture correctly. The problem besides internal flaws is that the grain size affects the strength of the platform so that it crushes when struck if not made large or robust like you found at 33:40. I've found some quartz that seemed to break more easily in burned out areas after a fire, so heat treating may actually be part of a solution. Thoughts?
I’ve never tried heating quartzite but I’m guessing you could. Also some people soak it to hydrate the stone and swear by it. Good luck and Thanks for watching 🤘
Im gonna be honest man. I was not expecting this to turn out that good seeing how horrible quality that stone is. Excellent job. I subscribed just for this
@@alaindonnell8924 No kidding, the landscape here in Virginia is littered with good quartzite and some times little cobbles of quartz. But other than that most of the chert and jasper deposits are protected by archaeological sites.
Quartzite may be the reason heat treating was invented. I don't know because I wasn't there at the time.
You could be right!👍
A lot of knappers seem to have an abundant supply of leave it where you found it. If the stone is bad all you are going to get is shattered rock.
Thanks for the info!😁
Hahaha, that was a good comment!

There is gonna be learning curve we that stuff.
Most definitely!
That looks like some rock an inexperienced napper like myself would not want to tackle. Thanks for sharing, I always learn something new.
I have some quartzite and now I’m nervous to try and knap it 😅
Next time you try quartzite and its time for the final reveal, throw away the last bit off camera and hold up a finished obsidian point.
😂😂👍

Thanks John!😁👍
you can work quartzite better with wood billets that's what we Virginia knappers use for quartzite.
I'm a Tarheel and we find that quartzite works best in a driveway.

did curt say where this material comes from? looks very similar to a material i get from arizona
He didn’t but I looked up the formation and I think it was located in Missouri or Arkansas.
Better than the finest dacite... 👌
