About Pumice: Origins, Applications, Chemical Makeup

Origins of Pumice. The word pumice is derived from the Latin word pumex, meaning foam.. Pumice is a textural rock formed from volcanic eruptions. Deep underground, molten rock incorporates water and other gases, and when the magma erupts from a vent, the gases flash off, leaving behind a frothy, vesicle-riven structure that quickly cools, solidifying the foamy structure.
