Speaking only for myself - and disclosing that I already have a lifetime supply of flint -
I think it's a fair price but it's hard to pull the trigger on a rock when the first picture looks like it's about to break into three pieces.
Breaking it up might actually add value in a case like this because the unknown is dealt with and internal patterns and colors can be analyzed.

I figured I was fair, I am cutting up smaller material at the moment, lots of banding and mottling of colors. May post some of those pics to show variations.

I have lots of flint ridge Nethers farm. There are lots of layered fractures. Lots of time it's hard to get a knife blade or decent cab because of them. Colored material usually is more solid and grey or grey striped not so good. I don't know!

I agree on lighter grey material that I found near the surface was very fractured. Darker grey and colored material I have some good preforms cut already but like you said lots of tumbling sized material lying around. Nice crystal vugs in some material though. That's why I brought this chunk back with me.

I thought same thing but i havent learned flintknappping that much yet. So i just keep cutting slabbettes and preforms if you will. Gives me cabs to work on during the winter.

Actually I've found that the cabochons are much better and (obviously) much more colorful with the heat treated material. If I were in your situation I would be strongly considering breaking this one up along the natural fractures and heat treating it. If the color pops you've got a real winner on your hands. |

Flint ridge takes a lot of heat!!! My turkey roaster with s crazy thermastat will go almost 600 degrees. That's not enough for knapping unless you slab it first. It is enough for cabbing to get the better colors.

Slab it and put it in kitty litter in a electric skillet, turkey roaster etc. Run it to 200 for overnite to dry water out. Otherwise it might explode. Then 100 degrees at a time until as hot as u can get flint ridge. Hold it for 6 hours and slowly dial it down so it doesn't crack. Don't go digging it out until it cools. Hot rock plus cool air means bad things!!! LOL. Google heat treating stone temps.
