By virtue of its spectacular volcanic origin and unique set of physical and chemical characteristics, pumice is truly versatile and valuable, widely used in industrial, agricultural, and consumer product applications. Though found in abundance worldwide, there are but few commercial pumice deposits that are of the purity, hardness, brightness and chemical composition necessary to be of such diverse value. The pumice products featured in our Pumice Products Store are sourced from the world’s purest commercial source of white pumice—the Hess Pumice deposit in Malad City, Idaho USA.
