The Secret and Miracle of Rust!
Rust is a general term for a series of iron oxides. Colloquially, the term is applied to red oxides,
formed by the reaction of iron and oxygen in the presence of water or air moisture.
Rust consists of hydrated Iron-III-oxides Fe2O3·nH2O and Iron-III-hydroxide (FeO(OH), Fe(OH)3).
Given sufficient time, oxygen, and water, any iron mass eventually converts entirely to rust
