Formation
When the lava is released from volcano, it undergoes a very rapid cooling which freezes the mechanisms of crystallization. The result is a volcanic glass with a uniform smooth texture. 0

Obsidian Formation

Obsidian formation took place millions of years ago. There are a variety of Obsidian Uses and the Obsidian Reserves are found in many countries around the world. The rocks in the earth’s crust continuously undergo changes in their composition which leads to formation of other rocks. Each rock has a unique formation process. Formation of Obsidian is explained below:
