Volcanic glass occurs in nature in various forms, the most well-known being obsidian. Unfortunately, a lot of industrial glass is also sold as Andara obsidian, Gaia Stone and Helenite, among others.    <\/p>\n\n<p>In the session I show several examples of natural obsidian, such as black, mahogany, snowflake, silver\/gold sheen obsidian and apache tears. Pumice, basalt slag and volcanic ash are also forms of volcanic glass.   <\/p>\n\n<p>I end the session with a few unusual varieties of volcanic glass, namely basaltic volcanic glass from the bottom of the ocean and &#8220;glazed&#8221; sandstone by contact with lava from the Eifel (Exotzamite).<\/p>\n\n<p>In the <a href=\"https:\/\/stapelvanstenen.nl\/en\/live-session-18-belazerite\/\" data-type=\"post\" data-id=\"544\">live session on Scammite<\/a>, I discuss fake volcanic glass such as Andara obsidian in more detail.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Recorded live session in which I discuss and show a variety of different forms of volcanic glass.
