Perlite is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently. It is an industrial mineral and a commercial product useful for its light weight after processing. Perlite is a non-renewable resource. The world reserves of perlite are estimated at 700 million tonnes. In 2011, 1.7 million tonnes were produced, mostly by Greece (500,000 t), United States (375,000 t) and Turkey (220,000 t). However, no information for China ? a leading producer ? was available. As of 2003, Greece was a leader in processed perlite production; however, estimates of perlite production from the report USGS Mineral Commodity Summaries 2013 indicate that the U.S. may have overtaken Greece.
