What is Pumice?

Pumice is a white, gray, pink, pale yellow or brown vesicular volcanic glass: its finer-grained equivalent is pumicite or volcanic ash. Made up of small rigid bubbles, pumice has a lightweight cellular structure in which each cell is sealed off from its neighbors by a thin membrane of glass providing low permeability. Scoria or cinder is a rusty red to black pyroclastic material in which the vesicles are coarser and more variable. Cell walls are thicker with abundant interconnections, and the texture is fine-grained and stony rather than glassy.
