Food Grade Diatomaceous Earth for radiant beauty, increased energy, and healthy rejuvenation It is a marvelous alternative to many toxic chemicals as well as a natural beauty aid for both people and their pets. Diatomaceous Earth packaged under the Lumino label comes from an extremely pure fresh water deposit. It is almost pure white and consists of at least 85% Silicon Dioxide. Darker colored Diatomaceous Earth often contains an excess of other minerals such as iron, or a high percentage of clay. What is Diatomaceous Earth and how is it processed? Diatomaceous Earth began life between 5 and 20 million years ago, as single-cell aquatic plants know as Diatoms. During the 15 millions years that they lived and died, truly unfathomable numbers of their microscopic skeletons accumulated at the bottom of what where once enormous fresh water lakes. Eventually the lakes disappeared leaving dried deposits of these fossilized skeletons. Subsequent geological events buried many of these deposits but more recent (just a few hundred thousand years ago) geological eruptions made some of the deeper deposits that are several hundred feet in depth extractable. The diatoms that produce Diatomaceous Earth grow in a unique way. Most plants use the sun’s energy to synthesize cellulose for the cell structure. Instead diatoms extract dissolved amorphous silica from the water. Silica is responsible for building their strong and stable skeletons. These naturally porous hard skeletons are what give DE its remarkably abrasive and absorbent abilities. There are also why DE is a good source of silica. Of the 600 DE deposits in the USA only four are considered Food Grade by the FDA. Not even these few Food Grade deposits are identical; some Food Grade deposits may contain higher amounts of sediment and clay. Depending on how the deposits are formed, sufficient clay particles can clog the pores of these fossilized shells reducing the effectiveness of the DE. There are thousands of products that contain Diatomaceous Earth. These included skin care products, toothpastes, foods, beverages, medicines, paints and water filters. The FDA lists DE as GRAS (Generally Recognized as Safe). How is Diatomaceous Earth Processed? Producing a small canister or bag of Diatomaceous Earth (DE) is a lengthy and expensive project. Our DE is from the Four Corners region of the Southwestern US and is prized for the purity and consistency of its ore deposits. The best DE is not just waiting to be picked up. It is buried and is covered by what is known as "overburden". This must be removed before the diatomite can be extracted with giant excavators. For the purest DE, darker layers are rejected, only the lightest layers are chosen for processing. The large pieces of excavated DE are then arranged so that solar energy can dry them out enough for crushing. After crushing they are moved to storage bins. The stored ore must then be carefully milled and further dried to preserve the structure of the diatoms that are responsible for it amazing abilities. After milling the DE is further sorted to removed impurities and foreign matter with a progression of sifters and traps. It is now ready to be jarred or bagged.
