To tell the truth i cant tell, it feels like
glass when tapped, but has dirt/sand coating the interior making it hard for me to determine. Im frightfully uninformed as to how to tell the difference without being able to see a raw surface such as the interior. I have a second piece that is very similar to this one, so similar i assume it was found (or made) at the same location. Ill post a few pics of that piece tomorrow.
