what have i got here?

What might it be and will it knap?i know the only way for me to know is to try but the big veins make it difficult to get a good piece and it looks like a bunch of balls melted together ...the outside looked awsome while it is cool looking am i wasting a purdy rock on hopes of knapping it???will it hold

I'm going to venture a guess. It looks like a quartzite. When I blew up the pic it appears that there is the formation of crystyls in the center like a goede. My limited experence tells me it's like concrete. But you have one nice rock formation it's a keeper. What area did you get it from?
Thanks Leroy

Looks like it will wear down those new boppers prematurely. I'd use hammerstones if you have some.

I have had some stuff that looks alot like that and the higher grade stuff knapps very well... the old timmers around here call it sugar stone... I have seen alotg of artifacts made from it and seems to have been one of the more desirable stone arond here...(I live south of lake of the ozark here in Missouri)

Looks like something id knap

[madcrow]

Yep, I would drag out the ogwood baseball bat for that stuff. Looks like it would be fun to smack on.  Just make sure nobody is straight across from you.  Those crystals hurt on impact.

Stoker i got it from someone deep on the heart of texas
Madcrow you are not lying i smacked it a good one a few chunks flew and one in the leg stuck and drew blood,its on now! Ps knapping with shorts may not be the best of ideas

[madcrow]

I usually knap in shorts and barefooted.  I guess if there no pain or blood, I'm not knapping.
