    Item name: Natural pumice stone

    Pumice stone is light porous acid volcanic rock having the composition of rhyolite, used for scouring and, in powdered form, as an abrasive and for polishing

    Pumice stone has a number of characteristics that combine to make it a valuable and versatile player in a variety of industrial processes and products.

    Pumice is amorphous and generally inert, has a neutral pH, yet is hard enough to be used as an abrasive. Yet, because of its porous nature, pumice is amazingly lightweight.

    The friable nature of pumice is one of its most significant characteristics—meaning pumice is easily crushed and refined without loosing its utility: at any grade—from half-inch aggregate to microfine powder—pumice remains abrasive, absorbent, non-compacting, lightweight.
