Rust is the common term, for a process, scientifically called oxidation, which occurs when oxygen, with the presence of, water or air moisture, or sodium (saltwater) comes in long-term contact with certain metals.
The recipe, for iron rust is as follows;
Take 2 parts iron (FE),
combine with 3 parts Oxygen (O),
and salt, if desired for taste.
To speed up the process, you may turn up the heat.
When exposed to the Earth’s atmosphere, under suitable conditions, most untreated metals, will slowly return to their natural state, as a metallic ore.
