Obsidian

Obsidian is a naturally occurring volcanic glass formed when lava extruded from a volcano cools rapidly with minimal crystal growth. It is an igneous rock, and its composition is similar to that of granite, though it lacks a crystalline structure. obsidian is typically dark in color, often black, but can also be brown, green, or even iridescent, depending on the presence of impurities. Historically, obsidian has been used to create sharp tools and weapons, mirrors, and decorative objects. It's known for its conchoidal fracture, meaning it breaks with smooth, curved surfaces, making it ideal for creating sharp edges.
