Pumice is produced in two forms: rock pumice and pumicite. "Pumicite" is a name given to very fine-grained pumice (less than 4 millimeters in diameter down to submillimeter sizes). The word can be used synonymously with "volcanic ash." It is mined from volcanic ash deposits, or it can be produced by crushing rock pumice.
