DEEP IN THE EARTH, in the fiery heart of a volcano, water mixes with molten rock, pressure builds, clawing relentlessly upward...erupting in a booming, spectacular release. The water trapped in the viscous, super-heated rock flashes to steam, blasting the magma into a frothy stone that cools, hardens, and falls to the earth as pumice—a foamed-glass stone that is hard yet friable, non-crystalline in structure, and naturally calcined, a combination of physio-chemical characteristics that make pumice incredibly useful to a variety of industries.
