Natural volcanic pumice harvested from Mt. Shasta located in California. Each summer Stuart Ward of Ward Pumice Co. gathers rocks released from the mountain by snow melt into the creek beds.
Callus removal: Soak and lather well to soften skin. Wet stone. Finding smoothest work face or point, scrub gently, increasing pressure as attune to process. Rinse often to slough away dead skin- pumice works with liquid. Remove thicker calluses over time. With patience you’ll file away gnarliest “alligator skin.” Finish with favorite moisturizer.
Pumice care: To unclog residue buildup, soak in hot soapy water. Scrub with wire brush, rinsing often. Handle with care; rocks can fracture if dropped. Dry in sun to purify, re-energize and restore buoyancy.
Thicker abrasive cell walls make these less buoyant than lighter kinds, but are far more durable- a cared for rock can last years.
