Primarily Petroliana Shop Talk Forums Non-Petro Discussions Non-petro Discussion and Showcase Difference between rust and patina?

The correct word for brass, copper or bronze turning green in verdigris. If you care to know the why's or how's, that can be looked up.

Verdigris is patina, which is the natural weathering process. That's not to say that patina is is limited to brass or copper. From my understanding, patina is the natural weathering process on anything, from your skin to metal to paint, etc.
