There is no such thing as a refined form of rust. The term rust is colloquial.

The forumla of rust is Fe2O3.nH2O. When the H2O is bored and leaves for a better place, the thing that remains is Fe2O3 - red iron oxide, the thing you refer as rust.

I'm curious too about the manufacturing process of tarnmatte. I didn't find a lot on the subject.
