RUST of a metal, the flower or calix thereof, procured by corroding and dissolving its superficial parts by some menstruum. Water is the great instrument or agent in producing rust; and hence oils, and other fatty bodies, secure metals from rust; water being no menstruum to oil, &c. and therefore not able to make its way through it.
All metals are liable to rust, even gold itself, if exposed to the fumes of sea-salt.
