Cold
Liver of Sulfur – Rich Brown Patina
Liver of sulfur or
sometimes-called Sulfurated Potash is a very old and traditional patina for
bronze, brass, or copper. It is easy to make and also to apply. This
patina is transparent. Let's look at the formula:
Mix 1 teaspoon Liver of sulfur with a pint of distilled – that’s it.
The mixture doesn’t keep more
than two days.
Apply the solution evenly to
the clean metal with a brush, sponge, or spray. Let sit for 5 minutes, and then
rinse with cold water.
For a darker color you may
reapply the solution.
After the metal has dried you
may wish to burnish the surface. This will even out the color. If a brass wire
brush is used to burnish, a more golden color will occur. Using a steel brush or
steel wool will create more of a brown color.
