The type of oxidation you get on iron depends on how much oxygen there is â lots and you get red rust, not too much and you get black rust (magnetite). There are chemical products you can buy that convert red rust to black rust, but these are generally toxic â not something you want to put on cookware.nlike red rust, black rust is protective and prevents corrosion. 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.
