It does not contain additives and is composed of trillions of microscopic unicellular plant skeletons called diatoms with a honeycombed, continuous pore structure. Diatomite is a siliceous sedimentary rock composed mainly of the fossilised skeletal remains of diatoms, which are single-celled organisms related to algae. Diatomite has a porous structure, which makes it ideal for use as insulation or as a filtering material (its primary use). 2004-11-01 There seems to be a lack of accord as to when a diatom is defined as subfossil or fossil so the following may work here:- Fossil - pre Holocene - earlier than 8000bc Subfossil - Holocene - 8000bc to anthropocene (18th century onwards) Recent - Anthropocene - (late 18th cent.

With a  Diatomaceous Earth is a silica hydroxide sedimentary rock , is amorphous, ( which means it does not have a definite crystalline structure and is therefore not a   Diatomite is a friable light-colored sedimentary rock that is mainly composed of the siliceous skeletal remains of diatoms. It is a very porous rock with a fine particle size and a low specific gravity. These properties make it useful as a filter media, an absorbent, and as a lightweight filler for rubber, paint, and plastics. Diatomite is a chalk-like, soft, friable, earthy, very fine-grained, siliceous sedimentary rock, usually light in color (white if pure, commonly buff to gray in situ, and rarely black). It is very finely porous, very low in density (floating on water at least until saturated), and essentially chemically inert in most liquids and gases. However, the most important diatomaceous raw material is diatomite. This is a porous, low-density, sedimentary rock formed by the accumulation and compaction of diatoms which may comprise 90% or more of the dry weight of the rock.

Deposits of diatomite are found all over the earth and range in color from white (very pure) to buff, grey and occasionally black. əs ˈɜːrθ /) – also known as D.E., diatomite, or kieselgur / kieselguhr – is a naturally occurring, soft, siliceous sedimentary rock that is easily crumbled into a fine white to off-white powder. It has a particle size ranging from less than 3 μm to more than 1 mm, but typically 10 to 200 μm.

It permanently improves heavy soils and horticultural growing media because it is indefinitely stable and non-compactable. Diatomite is a sedimentary rock mainly composed of the fossilized remains of unicellular fresh water plants known as Diatoms.

Diatomite protects against rot, and can slowly release silica to orchids that love it. It is often used as a component in other orchid media. With an ideal particle size of 10 mm - 25 mm, Diatomite Rock acts as a water and nutrient reservoir for plant roots enabling them to withstand common environmental stresses, such as drought and temperature extremes, more easily.

Diatomite rock

The streak of Diatomite is white whereas its fracture is not available. Luster of Diatomite is the interaction of light with the surface of Diatomite. Diatomite is a near pure sedimentary deposit consisting almost entirely of silica. The Greeks first used diatomite over 2,000 years ago in pottery and brick. There are many diatomite deposits throughout the world, but those of high-purity which are commercially viable are rare.
