Obsidian--Gift of the Volcano Curated by: KK
Obsidian is often referred to as volcanic glass. This silica-rich natural glass typically is very black, shiny, and glassy, but may be red-brown due to iron. Its conchoidal fracture can produce sharp edges, making it an important archaeological material due to its use in knives and arrows. http://www.ucl.ac.uk/es/impact/geology/london/glossary/rocks/igneous/obsidian
