Finds from tonight. Neat material question.

[A. Grignon]

My friend found the base of the point and it was really her first time out so she is all excited to find out how old and what it might have looked like. If you fellas could help out at all it would be greatly appreciated.

Also, I found a very cool piece of flint. Cannot really tell if it was worked or not, possibly at one time, but the material is beautiful and I really can't say I have seen anything like it around this area.
Both found tonight in South Eastern Wisconsin.

You're right, that is beautiful material. I wonder what it is Congratulations to your friend for her first finds!!

Someone will come along soon and tell you what it is, I'm sure.

I am not sure what that Bifuracate base one was it is way out of my area but that second picture is worked.That is the prettiest material I think I have ever seen. I sure hope some of these collectors will chime in on both. Man that is killer material!!

[Treefrog]

wow Id love to have some stuff made from that... awesome!!

Is there any chance it could be some kind of variation of Kentucky Agate? There seems to be a variety

The base is from the Early Archaic cluster of points like Big Sandy, Osceola, Hemphill, etc. My guess is probably a Hemphill. Others may say Graham Cave, but I don't think it is.

If your in the area around Ohio or even in Ohio I would say that is Flint Ridge Flint. All I have to say it is really awesome material and can you imagine what the finished product looked like? That is one of the prettiest pieces of stone that I have seen. Next to Horse Creek Chert and a few others.............Nice find wish it were whole!!! Still a highlight to see!!!...........GTP

The colorful piece is heat-treated Warsaw tabular chert. It is a very commonly used material here in eastern Iowa but I have no idea of how common it is in Wisconsin. Usually Warsaw is a plain flat grey but it develops the pink and red hues towards the exterior of the slab when it is heat-treated. This is absolutely one of my favorite materials in my area as the tabular (if you're wondering tabular means this chert is found in natural layers or slabs) nature of the stone lends itself to making very nice thin pieces and the heat treating gives the stone that nice smooth, almost waxy texture.

latrans - I thought Warsaw was the geological formation name for what we generally call Dover chert from Western KY / Western TN and is very common in that area? Maybe there are two different Warsaw cherts or flints out there but the Warsaw I'm used to is completely different. Any guidance you can offer is appreciated.

Looks like it could be heat treated Spergen Chert:

Spergen Chert, Light and medium gray or yellowish tan and brown.
Heat treatment alters tan and brown pieces to a reddish color.

Heat treatment alters tan tabular pieces to maroon with an off-white cortex

Probably the easiest thing to do would be to google Warsaw chert. You will find several helpful references.

That is probably the most beautiful worked material I’ve seen. I keep all unique pieces and here is an inspiration. Here’s a link to a worked piece that slightly compare to yours. There are folks who want that color and your piece meets the criteria. Not sure of the material but this shows that people collect worked pieces based on color/material. Not sure if this helps.
