material choice?
« on: April 15, 2009, 04:43:30 am »
I know a guy on another forum, who is going to send me some stone. He is in eastern Washington. He said he can get chert, flint, and obsidian. AFAIK, he is not a knapper, so he wants to know what I want, how big, etc.
I am in Ga and new to knapping, so what size should I ask for, obviouslly must be able to ship in a flatrate box. What about choices in material? So far I told him at least fist sized, other than some small bits for my nephew's tumbler, and material choice, some of everything. I think it would be better for learning to have choices, although I also lean towards staying with one material to gain consistency and experience.
Thoughts?

the bigger the better. seriously if one stone takes up the whole box its perfect. big rocks give you more time to practice percussion flaking with a good chance of getting some usable material. a small stone can be ruined with one bad hit.

Jamie's right on with the bigger the better advice. If he's in WA state, I would get mostly obs. A lot easier to work and you don't have to heat treat or anything.

Like everybody else said, bigger is better. Small cobbles are often to thick to preform unless you're really good and are too smal to get point-sized spalls from. With a big piece, you can knock off point-sized spalls, then biface what's left of the core into a bigger blade.

Progress might have been all right once but it's gone on for far too long.

I'll pass the info, and keep my fingers crossed. I wish I had a saw and could slab to save material. Might be easier if I transition from learning with glass. Seems funny to mail a rock though...

I just had a neighbor offer to bring me a truckload of "coral" boulders from Florida. Is it any good?

Dave: Sounds like you've been working with glass? If so, old TV picture tubes are great for learning the thinning process. Thick bottle bottoms, and window glass also. Might get cofortable with some of that before bashing on rocks :). As for the coral, it'll most likely have to be heat treated before you can work it. But if it's free, get ya a truckload - I would 8).
