Chemically benign and abundant, minimally processed with a very low carbon footprint.  Pumice is a naturally calcined volcanic glass foam consisting of highly vesicular strands of permeated with tiny air bubbles making this Pumice highly porous allowing it to hold both water and air. These frothy, friable glass vesicles afford pumice its unique and infinitely useful qualities.  Pumice's hardness property (see the General Physical Properties below) allows this Pumice to maintain its structure, the particles remain sharp-edged when processed to even a sub-micron size.\u003c\/p\u003e\r\n\r\n\u003cp\u003eAll Pumice is not created equal.  This Pumice is \u003cstrong\u003emined in an environmentally low-impact method\u003c\/strong\u003e and is naturally low in impurities.  Pumice is a non-botanical, sustainable, gentle exfoliant that has been used successfully for years.
