Obsidian is a naturally occurring volcanic glass formed as an extrusive igneous rock. It is produced when felsic lava extruded from a volcano cools rapidly without crystal growth. Pure obsidian is usually dark in appearance though the colour varies depending on the presence of impurities. Iron and magnesium typically give the obsidian a dark green to brown to black colour. Traces of obsidian being used as weapon/tools date as far back as 7,000 years ago. Obsidian was highly valued in the ancient world for arrowheads and blades.
