Sometimes we use acid to make a very thin passivation membrane on the surface to protect from rust. The basic principle is to use an acid like nitric or sulfuric in very high concentration (>70%). I've devised a special way of passivation that made this Gibeon slice show many colors from different angles on the surface - blue, gold, pink, brown. More about passivation here
