Mnopali Posted October 21, 2022 Share Posted October 21, 2022 (edited) I found these in Washington County Maryland (live in Central PA) while staying at an Airbnb. They were lying in and around a small creek. I've never seen anything like these before. I kept thinking they were peices of wood but was surprised to find them to be rocks when I picked them up. I also found this large peice of quartz? I have no idea so what do you all think? Edited October 21, 2022 by Mnopali Add tags Link to comment Share on other sites More sharing options...
Brandy Cole Posted October 21, 2022 Share Posted October 21, 2022 Can you take some more pictures of the second item from different angles in more light? Link to comment Share on other sites More sharing options...
Lone Hunter Posted October 21, 2022 Share Posted October 21, 2022 I think the first one may be slag. 1 Link to comment Share on other sites More sharing options...
FranzBernhard Posted October 21, 2022 Share Posted October 21, 2022 Last one is very probably a piece of quartz quartz. I also got the slag vibe for the dark ones, but I am not totally sure. Overall texture is a little bit strange, but it looks somewhat glassy with incipient flow texture. I can see also some tiny bubbles? @Mnopali, would you like to break off a small piece from one of the dark specimen and show us the interior? You may also try a streak test - scratch the fresh break along some rough porcelain, like the underside of a toilet tank. Franz Bernhard 1 Link to comment Share on other sites More sharing options...

FranzBernhard Posted October 21, 2022 Share Posted October 21, 2022 Are there lots of small bubbles in the fresh break? I think, I can see some. Franz Bernhard Link to comment Share on other sites More sharing options...
