Question about Texas rock

[Blacktail]

I got some rocks from a friend that is working in the San Antonio area and I didn't give him any description on how to find knapable rock so in my opinion he did a really good job on finding these two pieces. So, for the Texas guys, what kind of rock is this? And do I need to do any cooking? Thanks so much, John.

[TRACY]

Just got some that looks like that. It is tough and sharp. It seems like a little heat will make it less tough, but I really like it. Maybe some of the Texas folks will enlighten us both as to the name of it.

thanks for the reply tracy...i cant wait to start banging on the stuff..john

Looks like Edwards or Pedernales. I'd start bifacing & if its a little tough a turkey roaster will tame it. You'll be amazed at how its knappability will change. It will make you want to move to Tx!

thanks so much tower...now is the edwards the gray rock and the other is pedernales....also what is a good hold time for the rock and how long...thanks again john

Tower is the one to help with the heat treating I am unable to need a turkey roaster and i will start playing around with it some...  Tracy hope that rock works out good for you.  I have about 150lbs of it left under my deck..  I can also get more anytime..

[Tower]

Depends on the size. Small spalls about 3 to 4 hrs. Larger ones. 5 or 6 hrs. That's what I'd do.  The white material may need a longer hold time. Try it at 3 to 4 & if it needs more put it in the pile that heating .

[Blacktail]

well i spalled out the bigger one and i got some pritty good pieces...it sounds like i could cook them at 400 for 3-4hrs...but i will do that tomorrow...thanks john

That sounds like it aughta work. Wish you could take a short drive to san antone blacktail, ha.. bring your one ton and i could show where to squat it with that stuff .

Funny you should say San Antone Paul.  Might be too far for blackhawk, but not for me; and I just got an email last night from a guy who guided me for hogs down there when I first came to Texas.  He said I should come down for some "extreme hog bowhunting" on a new ranch.  Maybe I could combine a rock and hog hunt?  My f150 is "squatable"... LOL.

You betcha George. lol . South of SA on I35 hang a right in Lytle, go to LaCoste and head south (i think) along the rr tracks. Just outside of town if ya wanna call it that past the grain elevators and feed store you'll start seeing farmlands, mostly corn. Those fields are nothing but perd! You can pick it along the fringes i would imagine but if you can find a farmer he'll probably pay you to haul some off, haha..
 Might as well come on down and join in blacktail .

[TRACY]

Man, I'm about ready to fly down and rent a uhaul and fill it up Seider, my wife said the same thing about picking up a turkey roaster on black Friday. I need to get one sooner so I can cook some rock and try it out.

I figure if i keep useing her toaster oven she will let me buy one faster..

[Blacktail]

thanks for the help...i would love to make a rock run down there or even move...but my wife said no way..she dont like the heat that much...john

[gstoneberg]

...but my wife said no way..she dont like the heat that much...john

Mine always said that too, until we moved here.  And then she started saying, "we have more nice days in March down here than we had the whole year in Nebraska.  I can put up with the heat for 3 months to get the other 9."  I'd only get her out of Texas kicking and screaming now...or if the grandchildren begged her.   I tried to get her to consider Alaska, wanted to live there for a few years to hunt as a resident, but no dice there at all.
