Deep Brown Patina creates a slow reacting brown finish on bronze, brass, and copper. On iron and steel, it will produce a quick dark brown patina with greys and blacks. On zinc, the finish is a fast developing yellow brown. It should not be used on stainless steel. Deep Brown Patina does not need to be diluted, but may be thinned with distilled water for lighter coats or colors. Additional coats will darken the patina.
