Black pumice stone
£5.00

Natural black volcanic pumice stones drilled through and threaded with cotton cord. Used wet to remove calluses and hardened dry skin. Pumice is formed by the sudden depressurisation of super-heated lava, usually during the more violent phases of volcanic eruptions, rapidly cooling as trapped gasses inside expand the lava petrifies into a remarkably light and sponge like form. Stones of very approximately 5cm diameter.
