Diatomaceous earth - Wikipedia
Diatomaceous earth , diatomite (/daɪˈætəmaɪt/ dy-AT-ə-myte), celite or kieselgur/kieselguhr is a naturally occurring, soft, siliceous sedimentary rock that can be crumbled into a fine white to off-white powder. It has a particle size ranging from more than 3 mm to less than 1 μm, but typically 10 to 200 μm. Depending on the granularity, this powder can have an abrasive feel, similar to pumice powder
