The obsidian is a naturally occurring volcanic glass formed.
Formed when the lava from a volcano cools rapidly with minimal crystal growth. Obsidian is formed from lava that is rich in silicon, oxygen, aluminium, sodium and potassium. It is commonly found within the margins of rhyolitic lava flows. These flows have a high content of silica, giving them a high viscosity, inhibiting the formation of mineral crystals. The lava forms natural glass as it cools rapidly.
