Title: Help Identifying Rock
Post by: CDC1911 on March 04, 2017, 11:31:52 am
Hello folks! I picked up this rock recently and I need help identify what it is and does it need heat treating. I am just starting out so any help would much appreciated.

Thanks!

Cd, just a quick guess with little info from where your located, I'm going to say looks like a Texas Amoeba type rock, some nee4d heat and some can be knapped raw. We have some Texas knapper on here that will probably be able to help ya a little more, That's my .02 worth :o Bob

Thanks everyone for the replies. I am in North Florida and I got the rock from a guy selling knapping supplies and he might have told me but I don't remember. I know so little at this point it probably would not have mattered if he did tell me. I am have trouble with it and was wondering if heat treating it would help.

Looks like good Pedernales to me. Some call it Perd. It should be pretty good chipping as is, but if it is not cooked, it will get glossier with some heat, maybe 400 - 450 degrees F for a few hours. Beware that cooking whole rocks is risky. They tend to explode. If you knock it down into big flakes, they can be cooked with less danger of exploding. Try it raw first.
