Obsidian is a naturally occurring volcanic glass that forms when molten lava cools rapidly. It is known for its smooth, shiny appearance and sharp edges.
Imagine obsidian as a piece of black glass that was created in the fiery depths of a volcano. Just like how the glass cools quickly to form obsidian, imagine your favorite ice cream melting on a hot summer day and then freezing instantly into a smooth, shiny treat.
