d_day Posted September 7, 2017 Share Posted September 7, 2017 My first impression is obsidian in perlite. Of course I could be wrong. That's just the impression I have from these pictures. Better pictures would help with a better ID. Best bet for an ID is a local university's geology department. Quote Link to comment Share on other sites More sharing options...
pondmn Posted September 7, 2017 Share Posted September 7, 2017 It might be obsidian as some has an outer crust... Suggest you take a hammer with glasses on and try to hit the tip and break it. If it breaks easily you should see obsidian on the inside and it should be shiny with sharp edges. Quote Link to comment Share on other sites More sharing options...
