rock collecting Saturday...

[paulc]

Spent about 8 or 9 hrs total driving around east GA looking for chert using a research paper from the 60's as my "map".  Was not very productive but I did get to see some cool stuff and a part of the state I rarely spend any time in.  Gonna keep looking of course but I will need to do some more work ahead of time and maybe I'll do more collecting and less looking.  Maybe 9 pcs of chert that a better knapper could get a point out of-the rest of what I found was almost chalk like layers and layers of poorly glued sand.  All in all a pretty neat day as long as collecting chert/flint wasn't the main objective of the day :-)

Looks like a couple possibilities in that last picture

It's all I can do to NOT skip out on work and try and knock a point out....P

it would probably work better heat treated. Where are you at in Ga?

[paulc]

Islands outside of Savannah...I did put the stone through the turkey roaster over night at 200 to drive out moisture w/out popping any of it, then on Sunday I worked the heat up to 450 by maybe 8pm. Left it at 450 maybe 2 hrs before unplugging it to cool overnight.

Should I try to get it hotter?

If what you did doesn't help, then try heating it a little longer. Right now it's a guessing game.

that looks a lot like what I gathered at Kentucky Lake once while we was fishing there.
It's like hard dry mud and abrading would just grind it away its so soft compared to good chert.
I just worked this out of one the other day thinking it was something else when I grabbed it.

Don't know if it'll do but still pretty dang cool, Paul.

Of the rock pictured on the chair this is all I have left...I think part of my problem is I don't know when to stop    There was one piece with a pre-existing hinge that I just had to pop off but it took most of the stone iwth it.  Really would have been a functional arrowhead with the hinge and now I got nothing...oh well. Live and learn.

The two pieces on my knee may yet have a point in them, they're still big enough if I can get them thinned down some more.  Not sure if I should cook them more, they do fracture okay, pretty linear so I am getting flakes off them.  But the stone is not as slick and glass-like as a lot of what I have purchased has been...would more time at 450 help?  Or should I get them hotter?  Or leave well enough alone-they do flake but its pretty tough working them.

thanks, Paul
