Pum"ice, n. Etym: [L. pumex, pumicis, prob. akin to spuma foam: cf.
AS. pumic-stan. Cf. Pounce a powder, Spume.] (Min.)
Definition: A very light porous volcanic scoria, usually of a gray color,
the pores of which are capillary and parallel, giving it a fibrous

watery vapor without liquid or plastic lava. It is much used, esp. in
the form of powder, for smoothing and polishing. Called also pumice
