Traditional Brown Patina Ferric Nitrate 32oz (249229)
Ferric Nitrate is a hot patina for bronze, brass, and copper. In addition, it is often used to rust iron and steel. Size: 32oz
Type: Ferric Nitrate
Ferric Nitrate is a hot patina for bronze, brass, and copper. It creates a beautiful stable orange rust on iron and steel. For a hot application, heat the bronze, brass or copper to about 180F to 220F. Apply the solution sparingly with a brush by working across the surface, or with a spray bottle in a fine mist. The bronze, brass or copper will first turn gold and then darken to a light brown. If the solution is strong and more heat is applied, a darker shade from red/brown to dark brownish purple can also be obtained. Depending on the surface you begin with, the effect could be either opaque or shiny. If applying on steel, apply to clean cold steel. Allow sufficient time to react accordingly -- this may take some time. When applied on steel, the patina will be chalky. Do not rinse after applying hot or cold. Seal thoroughly with a clear coat.
