OBSIDIAN

Lipari, Aeolian Islands, Italy
 
Obsidian is a natural volcanic glass, formed when lava from a volcano cools extremely quickly leaving no time for crystals to grow.   
  
The lava that produces obsidian is usually sticky and highly viscous, resulting in explosively violent volcanic eruptions. 
  

Obsidian was used for the production of stone tools and Lipari obsidian has been widely exploited by prehistoric peoples throughout the Mediterranean.

  

Caution: Just like man-made glass, broken pieces of obsidian have very sharp edges.
