Antiquing Patina creates an aged brown to black finish on bronze, brass, and copper. On iron, steel, aluminum, and zinc, it will produce a grey to black patina. It should not be used on stainless steel. Antiquing Patina does not need to be diluted, but may be thinned with distilled water for a lighter finish. This cold patina is commonly used on the Metal Coatings and as a base for Traditional Green Patinas.
