    a very light porous volcanic scoria, usually of a gray color, the pores of which are capillary and parallel, giving it a fibrous structure.

    Etymology: [L. pumex, pumicis, prob. akin to spuma foam: cf. AS. pumic-stn. Cf. Pounce a powder, Spume.]


  1. Pumice

    Pumice is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. It is typically light colored. Scoria is another vesicular volcanic rock that differs from pumice in having larger vesicles and thicker vesicle walls and being dark colored and denser. Pumice is created when super-heated, highly pressurized rock is violently ejected from a volcano. The unusual foamy configuration of pumice happens because of simultaneous rapid cooling and rapid depressurization. The depressurization creates bubbles by lowering the solubility of gases that are dissolved in the lava, causing the gases to rapidly exsolve. The simultaneous cooling and depressurization freezes the bubbles in the matrix.
