Title: Unknown Rhyolite
Post by: vitzitziltecpatl on March 11, 2018, 03:53:58 PM

Anyone know the source location for this rough? It's a single chunk that was different in a parcel of "Spiderweb", I think.

Top left is a heel. Just below it is the back of a "tester" chip from that heel. The tester is polished (loosely speaking) to 3000 grit just to see how it might work up. Maybe the wildest Rhyolite we've ever had. Wish there had been more of it.

Don't know what it is, but I'm pretty sure the piece in the third picture is staring at me resentfully.

Nice  looking material. Hope it polishes well for you.
