Production of pumice in the United States during 2011 was estimated to be 380 kt (420,000 st), a 3-percent decrease compared with 2010. The unit value of pumice varied by end use in 2011. Pumice used as an abrasive was priced at $10.39/t ($9.30/st), while specialty-grade pumice, used in cosmetics, filtration or precision grinding, was priced as high as $150/t ($130/st) on a spot basis.
