Understanding Obsidian

Obsidian is a naturally occurring volcanic glass, formed when lava cools rapidly without enough time to crystallize. Its composition typically involves high silica content, giving it a glassy texture. Interestingly, this rapid cooling process results in a smooth, uniform structure highly effective for cutting tools.

• Physical Properties: Obsidian is hard but brittle, similar to glass. It fractures with very sharp edges, which makes it an excellent material for cutting blades.
• Color Variations: While commonly black, obsidian can also be found in shades of brown, green, and even rare rainbow or snowflake patterns.

Historical Uses of Obsidian
