Pumice -"the stone that floats"

Pumice is high in silica (60-75%), and cooling is so fast it has no crystal structure.  It's classified as volcanic glass, and in the 5 to 6 MOHS scale, with a melting point between 1,350 and 1,700 degrees C.  Other pumice mineral include aluminum oxide (13-17%); ferric oxide (1-3%) sodium oxide (3.6%) and potassium (4.5%)




Pumice is an outstanding versatile stone and tool of nature since ancient Roman times.  Our "true grit" pumice comes from Mount Shasta, CA and delivered in true form.   Store bought pumice is 99% adulterated (granulated, powered and then glued back together and injected into molds.)   A2Z's pumice is direct from nature from Stuart Ward's collection.  Our pumice was formed when escaping gasses in airborne molten lava created solid form, thus creating one handy elemental tool for us!   A stone age tool for the 21st Century!


Below are some of the uses; but I'm sure you can create more!

Metaphysical Uses


According to sources, real pumice (not reground and glued together), can be used to foster emotional healing and cleansing negative energies.  This makes sense as the natural ability to soak up like a sponge.    The author, Melody, in the "Love is in the Earth" book indicates that pumice takes on negativity in any situation and is good for helping one bounce back when feeling depressed.  This buoyant stone serves as "a reminder  not to sink into despaired when faced with heavy problems".  She further notes the stone is ruled by Aquarius and can serve as a consensus rock among people coming together for a single-mined purpose."  Stone vibrates at 5 frequency.

CARE of your Pumice To unclog residue buildup after constant use, soak in hot soapy water.  Scrub with wire brush, rinsing often.  Handle with care as rocks can fracture if dropped.  Dry in sun to purify, re-energize and restore buoyancy.  Please always use your stone mindfully.  Do not use on inflamed skin or severe cracks as the grit will irritate.   Pumice may scratch porcelain and stainless steel sinks.
