Liver of Sulfur


Liver of sulfur is a chemical compound used in metalworking to create antique-looking patinas on silver and copper bearing alloys such as brass, bronze and copper.

The patina process is very simple. You start by mixing up the liver of sulfur with water, then simply dip, soak or paint the solution onto your metal. The solution reacts with the metal and results in either a colorful or darkened patina over the entire surface of the metal. Usually, color is wanted only in recessed areas and not on raised surfaces, so those areas are usually polished, leaving the patina only where desired.
