The color(s) achieved by a specific patina solution depends upon the metal or alloy to which it is applied, the age and the strength of the patina mixture, the time and temperature of the exposure, and the process used to apply the solution. Cool Tools offers liver of sulfur in a solid lump form and in a stabilized gel, called Patina Gel. These two products are perhaps the most widely used patinas by jewelry artists for silver, copper, bronze and brass.
