Ferric Nitrate/Ferric Chloride Patina produces a transparent red brown finish when applied hot to bronze, brass, and copper. Similar to Ferric Nitrate Patina, the final colour and opacity is determined by the application process. Additional coats will turn darker brown and more opaque. Ferric Nitrate/Ferric Chloride Patina does not need to be diluted before use. Heat the metal to about 180°F-220°F (82°C – 93°C) and apply with a brush, spray bottle or sponge. If applied full strength, it will create a dark brown. If diluted 1:1 with distilled water it will create a rusty shade of brown. Don’t use on aluminium. Apply a clear sealer or wax after the patina is dry.
