I recently read a description of rust bluing, which explains the patina revealed by Simichrome and Maglight as an inevitable (and ultimately undesirable) result of the process.

It made me wonder about salt bluing. Patina is rust, result of a rusting process. Since salt blue is not explicitly a rusting process, would it necessarily result in patina?
