Obsidian is a naturally occurring volcanic glass formed as an extrusive igneous rock.
It is produced when felsic lava extruded from a volcano cools without crystal growth.
Obsidian is commonly found within the margins of rhyolitic lava flows known as obsidian flows,
where the chemical composition (high silica content) 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. Because of this lack of crystal structure,
obsidian blade edges can reach almost molecular thinness, leading to its ancient
use as projectile points, and its modern use as surgical scalpel blades.
