description
Naturally calcined by nature, pumice is an incredibly versatile mineral that enjoys wide use over a variety of industries because even processed to an ultrafine powder, pumice retains its useful characteristics. Hess Pumice mines and refines the purest, whitest commercial deposit of pumice on the planet and ships it worldwide for use as a pozzolan in concrete, cementitious grout, and plaster; as a gentle abrasive and polish; as a superfine exfoliant for cosmetics; as filtration media; as a non-crystalline silica filler for paints and an extender for other compounds; as a soil amendment to improve nutrient and water holding capabilities in poor soils; as a grow media for soilless high-performance growth systems; as a lightweight aggregate for precast concrete products and building blocks.
