What is Patina, and What Does it Have to Do With Metal Wall Tiles?

Patina is the result of an oxidation reaction occurring between the metal and the oxygen in the air. This reaction results in a protective and distinctive finish on the surface of the metal wall tile. Patina is a sought after effect, and is usually offered at a premium. Various types of metal tiles produce different colors of patina. For example, bronze produces a luminous brown color that gradually displays a warmer shade over time. If moisture is in the air, patina can change further. Bronze tiles develop a green tint in presence of humidity.
