This is the real deal, the genuine article; true grit! In the 1780s, when Mt. Shasta erupted, these pumice stones started out as globs of molten lava that were flung miles high during eruption and then rounded aerodynamically by nature on its way back to earth.

Typical chemical properties of pumice varies from volcano to volcano and even between eruptions of the same volcano over time as each eruption has a unique recipe of molten minerals: Silica, 60-75% (makes it abrasive and whitish; higher the silica, whiter the stone); aluminum oxide (makes it highly resistant to fire and heat) 13-17%; ferric oxide, 1-3%; sodium oxide, 3.6%; potassium, 4.5%.
