Because patination involves tarnishing or oxidizing the metal, genuine gold is not used because it resists tarnishing. Genuine gold can be used for a contrasting accent; it will not oxidize to create a patina. Metals appropriate for patination include copper, silver, and Dutch metal leaf (aka composition gold), which is gold in color.
Chemical patinas are achieved by oxidizing the metal leaf with mild acids. Patina chemicals are mild acids that will change the color of the metal leaf (silver, coppe
