Perlite | Imerys

Perlite is a generic term for naturally occurring siliceous rock. It is a form of natural glass which like pitchstone, obsidian and other similar contains "combined water". Perlite (containing 1,9% – 4,8% wt. "chemical" or combined water) was formed over a few million years by the chemical weathering of obsidian at the earth's surface.
