Patina | Metal Patina | Metal Finishing
A patina is a surface coating on a bare metal surface formed by chemical reaction. It is distinctive over applied coatings like painting and powder coating in that the effect is caused by actually reacting a solution with the metal surface.
Metals react with moist air on their own in a gradual pace. By using a blend of acids and/or salts, the process is greatly accelerated to a time frame that is managable for decorative application.
