Diatomaceous Earth Many thousands of years ago, these tiny siliceous particles called 'frustules' were living single celled plants called Diatoms. These tiny aquatic organisms lived in both salt water and freshwater, nearly covering the entire planet. After these plants died, the silica based cell wall is left behind, still intact. These microscopic skeletal remains make up the billions of particles that form the silky off white powder we call Diatomaceous Earth. When shopping for your favorite brand of Diatomaceous Earth, there are a number of fact checks that should be done quickly before you consider purchg. First of all, is it food grade? This means that it is a product deemed safe to be used in food manufacturing, as a processing aid. Secondly, you can look for whether it is from freshwater or saltwater sources. Freshwater typically helps to a lower level of crystalline silica. And lastly, check that the product is 'uncalcined'. This means that it has not been altered by high temperatures, which would alter the amorphous silica into a more abrasive form.
