Pumice

Igneous Rocks

A volcanic rock of extremely vesicular rough-textured volcanic glass, typically light colored, with a porosity of 64 to 85 percent by volume. It floats on water, sometimes for years, until it becomes waterlogged and sinks, and pumice rafts from underwater eruptions can be a hazard for ships. Its dark, denser cousin with larger vesicles is scoria. This description is adapted from Wikipedia contributors under CC BY-SA 4.0; changes were made. https://creativecommons.org/licenses/by-sa/4.0/

  • Lead section and Properties
    Pumice has a porosity of 64-85% by volume and it floats on water, possibly for years, until it eventually becomes waterlogged and sinks.
  • Other uses
    It is also used as an abrasive, especially in polishes, pencil erasers, and the production of stone-washed jeans.
  • Lead section
    Pumice is composed of highly microvesicular volcanic glass with very thin, translucent bubble walls of pyroclastic igneous rock.
