Lumino Diatomaceous Earth

Pure Food Grade

Diatomaceous Earth (DE) is not earth or dirt. It is the fossilized remains of Melosira preicelanica, microscopic shells created by one-celled aquatic plants (diatoms). Over the eons, as these diatoms fossilized, they retained their tubular shape and holes. Their shape and hardness produces extremely pure and consistent DE.

There are different grades of DE. Of the 600 deposits in the US, only four are considered food grade. Lumino DE is rated food-grade by the USDA and considered GRAS (generally regarded as safe) by the FDA. It is almost pure white and consists of 89-94% silicon dioxide plus other trace minerals.

There are two original sources for DE: fresh water and salt water. Our fresh water deposit began eons ago as pure snow. The snow's run off provided the water source the diatoms lived in. Diatoms in fresh water form a harder more uniform shaped shell than those in salt water.

The silica in Lumino DE is amorphous. This is silica in its naturally occurring state. It is a trace mineral every mammal on the planet needs for survival. DE is dangerous when the silica in it is crystallized by exposure to extreme heat. This type of DE is never considered food grade.
