    Also, things bond better to magnetite than bare iron (for example, polymerized fat). Black rust is not sufficient by itself to protect cast iron from corrosion. It must be insulated from air and water with a layer of oil, and also it's easily removed. But when black rust is bound up in polymerized fat, the result is probably a better seasoning.

    Iron Oxide Black

    Synthetic black iron is fluffier and lighter than synthetic red iron oxide (a bag of black iron is much larger than a bag of red). It is a very fine powder, will easily wash through a 325 mesh screen. Synthetic black iron does not agglomerate as badly as red iron, thus it disperses in glaze slurries better (thus avoiding fired speckle).
