Obsidian
Obsidian is a naturally occurring volcanic glass formed as an extrusive igneous rock.
Obsidian is produced when felsic lava extruded from a volcano cools rapidly with minimal crystal growth. It is commonly found within the margins of rhyolitic lava flows known as obsidian flows, where the chemical composition (high silica content) causes a high viscosity which, upon rapid cooling, forms a natural glass from the lava. The inhibition of atomic diffusion through this highly viscous lava explains the lack of crystal growth. Obsidian is hard, brittle,
family at this point and it's very disappointing for me. My true passion is music and, in this day and age, it's really amazing that you can still make an impact through this art.
