What is Diatomaceous Earth?
Diatomaceous earth (DE) is a mineral silica that has an elaborate structure worked by nature into a labyrinth of tiny holes. No other silica source, whether mined or artificially produced, has such a structure. Each diatom is peppered with thousands of holes ranging from a few microns in diameter down to submicron diameters. The number and size of these holes vary with the species. It is the combination of the composition of natural silica, the structure of its diatom particles, and of the network of holes in that structure, that confers the unique properties of these multi-functional mineral products.
Geology
Diatomaceous earth is a sedimentary rock composed of the prehistoric skeletal remains of single-cell aquatic plants called diatoms. Most are fossilized and were deposited in the Miocene period, some 15 million years ago. Some deposits are saltwater but most are from freshwater sources. The profusion of shapes results in an extremely low density diatomaceous earth powder, with excellent filtration characteristics.
