Obsidian gets its name from the Roman Obsius who found it in Ethiopia and brought it back. A natural forming glass that is created from volcanic activity, it does have the same makeup as granite, but since the magma cools so quickly, obsidian doesn’t have the change to crystallize. While Obsidian is harder than window glass, it scratches very easily. It has been used for tool making and jewelry for centuries. It is found in Iceland, Italy, Japan, Wyoming, and Hawaii.
