Title: what rock is this?
Post by: le0n on April 19, 2016, 09:51:45 pm

i picked one piece up from a rock shop in Marfa, Tx.

the shop owner didn't know what it was. he even questioned if it was synthetic.

it looked knappable, so i brought it back with me.

in the sunlight, it looks sort of like gray plastic.

thanks in advance.

The second picture onward look like Novaculite to my eyes.

^^ Thanks.

It knaps like dacite, but those red veins just come apart when you look at them.

I tried to get some vein-free flakes, but it just wasn't happening. I'll most likely just leave it alone and focus my time elsewhere.

It looks like grey novaculite to me also.

Looks like a good time!

^^ thanks.

i can get small flakes/points from it, so i may save it for when i'm really rock poor.

I'm always rock poor, so I would already have it destroyed.  ;D

   Those cracks are from water and freezing some where through time.

That's TX Chert. 
It's a variant of Edwards.   It should take heat very well.

i just googled that and found a photo of one made from this material:

that looks exactly like the stuff 8)

thanks.

instead of making a new thread, can i post another rock for identification?

i knocked a slab off of it earlier; but thinking i should probably save this stuff until i have time to treat it.

edit: after searching around online, it appears to be a rhyolite. if so, i don't have to wait to heat treat it, hah hah.

i tried flaking a small chubby piece to see how it acted. it's very tough and the flakes almost fracture into powder as they run.
