Black Obsidian: The Volcanic Glass and Its Geological Formation
Pick up a piece of black obsidian and you might mistake it for a chunk of dark, glossy rock—until you notice how the light catches its surface. It isn’t a rock in the ordinary sense. Formed when lava chills too quickly for crystals to grow, obsidian is a volcanic glass, a material that has sharpened tools, puzzled geologists, and even found its way into surgical research. Its chemical fingerprint is nearly identical to that of granite, yet its structure tells a different story entirely. Understa
- Black obsidian is a volcanic glass, not a crystalline rock.
- It forms when lava cools rapidly, preventing crystal growth.
- Obsidian has a chemical composition similar to granite.
- It has been used for sharp tools and in surgical research.
