Information Card Included
Pumice is a textural term for a volcanic rock that is solidified frothy lava typically created when super-heated, highly pressurized rock is violently ejected from a volcano. It can be formed when lava and water are mixed.
Pumice is composed of highly microvesicular glass pyroclastic with very thin, translucent bubble walls of extrusive igneous rock. It is commonly, but not exclusively of silicic or felsic to intermediate in composition. Pumice is commonly pale in color, ranging from white, cream, blue, or grey, to green-brown.
