Obsidian bubbles. Artwork of a magnified view of bubbles of volatiles (volcanic gases) trapped in a specimen of obsidian (volcanic glass). Obsidian forms when magma (molten rock) is ejected into the air during volcanic activity and chills (cools) so quickly that mineral crystals do not have a chance to form | |
