After a volcano explodes Obsidian is the material that remains! Hard, Cutting, this dragon is pure Power! Every single edge he has is a deadly knive!
- 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 with minimum crystal growth. Obsidian is commonly found within the margins of rhyolitic lava flows known as obsidian flows, where the chemical composition (high silicacontent) induces a high viscosity and polymerization degree of the lava. The inhibition of atomic diffusion through this highly viscous and polymerized lava explains the lack of crystal growth. Obsidian is hard and brittle; it therefore fractures with very sharp edges, which had been used in the past in cutting and piercing tools, and has been used experimentally as surgical scalpel blades.
