1. pumicenoun

   A light, porous type of pyroclastic igneous rock, formed during explosive volcanic eruptions when liquid lava is ejected into the air as a froth containing masses of gas bubbles. As the lava solidifies, the bubbles are frozen into the rock.

1. Pumicenoun

   The pumice is evidently a slag or cinder of some fossil, originally bearing another form, and only reduced to this state by the violent action of fire: it is a lax and spungy matter full of little pores and cavities, found in masses of different sizes and shapes, of a pale, whitish, grey colour: the pumice is found in many parts of the world, but particularly about the burning mountains Etna, Vesuvius and Hecla: it is used as a dentifrice. John Hill Materia Medica.

   Etymology: pumex, pumicis, Lat.

   So long I shot, that all was spent,
   Though pumice stones I hastily hent,
   And threw; but nought availed. Edmund Spenser.

   Etna and Vesuvius, which consist upon sulphur, shoot forth smoke, ashes and pumice, but no water. Francis Bacon.

   Near the Lucrine lake,
   Steams of sulphur raise a stifling heat,
   And through the pores of the warm pumice sweat. Addison.

1. Pumice

   Pumice ( ), called pumicite in its powdered or dust form, 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, 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 (including water and CO2) that are dissolved in the lava, causing the gases to rapidly exsolve (like the bubbles of CO2 that appear when a carbonated drink is opened). The simultaneous cooling and depressurization freeze the bubbles in a matrix. Eruptions under water are rapidly cooled and the large volume of pumice created can be a shipping hazard for cargo ships.

1. pumice

   Pumice is a type of volcanic rock that is highly porous and lightweight due to its content of highly pressurized gas. It is formed during the explosive eruption of certain types of volcanoes. The rapid cooling and depressurization of the ejected magma trap gas bubbles inside the rock, giving it a spongy appearance. Pumice is commonly used in beauty and health products for its abrasive properties, as well as in construction and gardening.

1. Pumicenoun

   a very light porous volcanic scoria, usually of a gray color, the pores of which are capillary and parallel, giving it a fibrous structure. It is supposed to be produced by the disengagement of watery vapor without liquid or plastic lava. It is much used, esp. in the form of powder, for smoothing and polishing. Called also pumice stone

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