Pumice is the cooled, hardened and ‘frothy’ part of volcanic lava, a pyroclastic, igneous rock. Liquid lava is ejected into the air as froth, containing masses of gas bubbles; as the lava solidifies, the bubbles are sealed into the rock.
Pumice is very porous and lightweight; it is the only rock that can float on water until it becomes water logged.
Various minerals occur in the many types of pumice, the most common are feldspar, augite, hornblende and zircon.
The word pumice is derived from the Latin word ‘pumex,’ meaning ‘foam.’
As pumice has no crystal structure, it is considered to be a glass.
In ancient Greece and Rome, it was used for the removal of excess hair, and was also used in toothpaste.
It has long been used as an abrasive in cleaning, polishing and scouring, and as an additive for lightweight construction materials.
Our Volcano foot mask both deodorises and cleanses the feet; as you wash the product off, the generous amount of pumice scours dead skin cells, leaving your skin perfectly polished.
Pumice is a powerful exfoliant; it is excellent for removing dead skin. We use it in both our You Snap The Whip and Running to the Embassy body butters to scrub away dead skin whilst the other ingredients cleanse and soften.
We also use pumice in our new Stepping Stone foot scrub.
