About Pumice: Origins, Applications, Chemical Makeup

Origins of Pumice. The word pumice is derived from the Latin word pumex, meaning foam.. Pumice is a textural rock formed from volcanic eruptions. Deep underground, molten rock incorporates water and other gases, and when the magma erupts from a vent, the gases flash off, leaving behind a frothy, vesicle-riven structure that quickly cools, solidifying the foamy structure.

What Are Acceptable Moisture Levels in Wood?

Percent moisture content in wood is the ratio of the weight of water compared to the overall weight of a piece of wood. A 10% moisture content reading means that 10% of a wood sample’s weight is due to water in the wood. If a board reads (Difficult to measure accurately) then the weight of the water equals the weight of that wood.
