PostPosted: Feb 18, 2017 17:45    Post subject: Colored Glass or Obsidian  

My mother who used to be a science teacher back in the 70's was given some pieces of this, some as big as my fist.
I am thinking it's colored glass, but before I make a decision, I thought I would post a few pictures.

What do you all think, glass or obsidian?

THank you,
David
