22 pounds of high quality, natural magnetite powder. Images show an 11 lb bag (you will receive 2 of these), a small example of the material, and a compositional analysis. Great for hydroponics, gardening, MEOW kettles and experiments of all kinds. Lowest delivered price per pound.

1 cup of magnetite powder weighs about 1 lb.  The material feels and handles like (very heavy!) bread flour.  It is sifted and dried.
