obsidian (volcanic glass, pyroclastic rock, ... Materials (Hierarchy Name))

 

Note: A dark, shiny glass formed in nature by the rapid cooling of lava. Obsidian is widely distributed and has been used since Paleolithic (before 3500 BCE) times for mirrors, weapons, tools, and jewelry. Obsidian is often black in color but may also be red, brown or green. It produces conchoidal fractures when cleaved. Sources of obsidian include Anatolia, Armenia, Ethiopia, Greece (Milos), Italy (Lipari, Eolie), Iceland, the U.S. (Wyoming), Mexico (Teotihuacan), Guatemala (Tikal), and Peru. Obsidian changes into pumice when it is melted.

Additional Notes:
Dutch ..... Een zuurresistent zwart of donkergekleurd vulkanisch glas, met een opvallende glans en een gewelfd, glimmend oppervlak wanneer het wordt gespleten. Het wordt gebruikt voor het maken van sieraden, pijlpunten en kunstvoorwerpen en is genoemd naar Obsius, die het ontdekt zou hebben. Obsidiaan verandert in puimsteen wanneer het wordt gesmolten.
