    The obsidian is a very cool igneous rock. It was used to form tools with sharp edges.

    Hi there room 12/13...A fine specimen of 'volcanic glass' thanks for sharing!! Brenden, Cole's dad mentioned it was used for its sharp edge. Can anyone tell us what kind of tool / implements were made using the rock and any other interesting facts?
