Obsidian, Triple Flow
Home Igneous Sedimentary Metamorphic Rock Cycle Triple Flow (TriFlow) Obsidian Triple Flow Obsidian is volcanic glass. The various colors of obsidian are a result of several factors. Clear varieties of obsidian contain very few opaque impurities or microscopic mineral crystals. Red or brown obsidian generally results from tiny crystals or inclusions of hematite or limonite…
