Hey, I found this while rooting around through my crates, and I'm not quite sure what it is. DSC_0480_Unkown quartz thingy by Stephan Telm, on Flickr I'm leaning toward limb-cast, but that pock-marked skin is weird. I guess some really hot ash could have basically vaporized the wood. Doesn't seem right for a fulgurite (not glass, plus they're usually hollow, from what I've seen). Just a nodule of crackly quartz that happens to be semi-cylindrical? What do the experts think?

That is crazy. The outside looks like volcanic material, but the inside does not.

Limb or root cast seems more likely to me. They sometimes do come with an outer surface like that - perhaps your theory about hot ash pockmarking it could be correct. Rotting wood surrounded by pebbles, rather than fine ash or soil that would form a mold to pick up more of the texture from the original wood surface, is another possibility.

I had a limbcast that looked like that.

Another vote for limbcast. Nice piece.
