Diatomaceous Earth: Calcined vs. Non-Calcined

Diatomaceous earth can be calcined or non-calcined. The difference between the two is very important depending on what purpose the DE is being used for. Calcined diatomaceous earth has been treated at a temperature above 1000 ºC. The purpose of this is to further harden the exoskeletons of the diatoms in order to create a better filtering agent.

What is Diatomaceous Earth and Why You Should

What Is Diatomaceous Earth? Diatomaceous earth is a chalk-like substance that is composed of fossilized diatoms that have formed together into silica deposits. The silica deposits are grounded into a fine powder called diatomaceous earth. There are two different grades of diatomaceous earth; food grade and pool grade. Food grade diatomaceous earth is safe to []
