Let’s be clear – Volcanic Ash is not Bentonite Clay, volcanic sand or volcanic pumice. Volcanic Ash comes straight out of the volcano as does volcanic pumice. However, pumice is as light as a feather and comes in small pebble sizes up to quite large, single rocks. Volcanic Ash, while it is feels and appears like black sand, it isn’t. Volcanic ash is made up of finely crushed particles under 2mm (.079 inches) and may be as small as 0.0025 inches (or 0.0635mm). Oh and it’s not really Volcanic Dust either as “ash” and “dust” are classified by a specific size of the “Tephra” and “Pyroclastics” (terms used to describe igneous rock material ejected from active volcanoes). Volcanic dust particles are less than 0.063 mm (0.0025 inches).
