diatomaceous earth,,, comments, uses, i have 10 lb food grade DE and wondering what are the various things our community does with it,,i put some in the catbox and on the critter for fleas,etc before they emerge, some sprinkled in all the house plants,,what else?
Applications
In 1866, Alfred Nobel discovered that nitroglycerin could be made much more stable if absorbed in diatomite. This allows much safer transport and handling than nitroglycerin in its raw form. He patented this mixture as dynamite in 1867, and the mixture is also referred to as guhr dynamite.
Filtration
The most common use (68%) of diatomaceous earth is as a filter medium, especially for swimming pools. It has a high porosity, because it is composed of microscopically-small, coffin-like, hollow particles. Diatomaceous earth (sometimes referred to by trademarked brand names such as Celite and Celatom) is used in chemistry as a filtration aid, to filter very fine particles that would otherwise pass through or clog filter paper. It is also used to filter water, particularly in the drinking water treatment process and in fish tanks, and other liquids, such as beer and wine. It can also filter syrups, sugar, and honey without removing or altering the color, taste, or nutritional properties of any of them.[8] Other industries such as paper, paints, ceramics, soap and detergents use it as a fulling material.

Abrasive
The oldest use of diatomite is as a very mild abrasive and, for this purpose, it has been used both in toothpaste and in metal polishes, as well as in some facial scrubs.
Pest control
Diatomite is used as an insecticide, due to its physico-sorptive properties. The fine powder absorbs lipids from the waxy outer layer of insects' exoskeletons, causing them to dehydrate. Arthropods die as a result of the water pressure deficiency, based on Fick's law of diffusion. This also works against gastropods and is commonly employed in gardening to defeat slugs. However, since slugs inhabit humid environments, efficacy is very low. It is sometimes mixed with an attractant or other additives to increase its effectiveness. Medical-grade diatomite is sometimes used to de-worm both animals and humans, with questionable efficacy. It is most commonly used in lieu of boric acid, and can be used to help control and eventually eliminate cockroach and flea infestations. This material has wide application for insect control in grain storage. It has also been used to control bedbug infestations, but this method may take weeks to work.
Absorbent
Its absorbent qualities make it useful for spill clean-up and the U.S. Centers for Disease Control recommends it to clean up toxic liquid spills. These qualities also lend themselves to use in facial masks to absorb excess oils.
It has been employed as a primary ingredient in a type of cat litter. The type of silica used in cat litter comes from freshwater sources and does not pose a significant health risk to pets or humans.
Thermal
Its thermal properties enable it to be used as the barrier material in some fire resistant safes. It is also used in evacuated powder insulation for use with cryogenics. Diatomaceous earth powder is inserted into the vacuum space to aid in the effectiveness of vacuum insulation.
DNA purification
Diatomite (Celite) can be used for the removal of DNA in the presence of a highly concentrated chaotropic agent such as sodium iodide, guanidinium chloride and guanidinium thiocyanate. As with other silicates, the diatomites will remove double stranded DNA but not RNA or proteins. The DNA can be extracted from the diatomites using low ionic strength buffers, including water, at neutral to slightly alkaline pH. Crude diatomites of a uniform size must first be washed in a heated acid such as 5M HCl. Calcination can further improve consistency of the material, while mild caustic treatment may improve adsorption with lower levels of chaotrophs.
Use in agriculture
Natural freshwater diatomaceous earth is used in agriculture for grain storage as an anticaking agent, as well as an insecticide. It is approved by the US Department of Agriculture as a feed supplement.
It is also used as a neutral anthelmintic (dewormer). Some farmers add it to their livestock and poultry feed to improve the health of animals. "Food Grade Diatomaceous Earth" is widely available in agricultural feed supply stores. It is acceptable as organic feed additive for livestock.
Hydroponics
Freshwater diatomite can be used as a growing medium in hydroponic gardens.
It is also used as a growing medium in potted plants, particularly as bonsai soil. Bonsai enthusiasts use it as a soil additive, or pot a bonsai tree in 100% diatomaceous earth. Like perlite, vermiculite, and expanded clay, it retains water and nutrients, while draining fast and freely, allowing high oxygen circulation within the growing medium.
