Obsidian Obsidian is a glass, or a super-cooled liquid that is liquid in all its properties except in its ability to flow easily (Cann 1983). As a glass, its atomic structure, by definition, is entirely disordered. Because of this it has no preferred direction of fracture and is entirely isotropic, at least when entirely aphyric. This property endows obsidian with its excellent flaking properties and extremely sharp edges when fractured. |
