Stainless Steel
Stainless steel was discovered in the 1900's, scientists found out that by adding at least 10% of Chromium to steel, a transparent layer would form on the surface of the steel that disallowed rusting by stopping oxidation. The transparent layer would heal itself, when injured by water, slight denting and scratching.
