Pumice, pumicite review

January 1, 2013

The article focuses on the industrial mineral pumice. It mentions the estimated production of pumice in the U.S. in 2010, price range, and total U.S. exports and imports. Described as an igneous volcanic rock, pumice has low density which allows it float on water and porous enough to be used as building aggregate. Pumice may also function as an absorbent material, a filter aid, and a polishing agent among others.
