Diatomaceous earth 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 1 micron to more than 1 millimeter, but typically 10 to 200 microns. This powder has an abrasive feel, similar to pumice powder, and is very light, due to its high porosity.
Milled Grade : A Milled Grade diatomaceous earth is suitable for pesticides, detergent and soap ranging from 100 to 500 mesh
