This obsidian has iron inclusions, causing most of the glass to be reddish brown, with black spots and swirls throughout. Found in many places around the world, Glass Butte, Oregon is a large producer of this stone. Obsidian has a conchoidal fracture, meaning it doesn’t break in any given pattern. It can however break into pieces sharper than steel. In fact, today obsidian is used to make surgical scalpels that are used in brain and spine surgeries. In the past it was used to make knives, as in the human sacrifice knives of the Aztecs, arrowheads and other sharp tools for skinning and butchering animals, cutting grains and making clothing.
