Oxen Study III (Cupric Nitrate Patina) 2022 by Conrad Hicks STIRpad
Transparent patinas are: • Cupric Nitrate • Ferric Nitrate • Potassium Dichromate • Sodium Thiosulphate. Cold Patinas. There are varieties of methods of applying cold patinas. What they have in common are that the chemicals are applied cold to the surface of the metal. The most common are:

Cupric nitrate brush application pattern. The balance of this paper will deal with the application of cupric nitrate patinas. This general-purpose patina may be applied hot or cold and may be built up to cover surfaces evenly with excellent adhesion. The solution is most easily applied to brass but holds better on copper.

Process. Hot process. Solution hot (180 to 190°F), metal hot (200°F), cold wash water applied after metal has cooled to around 100°F. Wash solution over metal surface, let dry, then wash piece in cool water. Repeat until color develops. For Yellow Green, dip in dilute nitric acid, then wash and dry. Back to Index.

Equal amounts of cupric nitrate and ammonium chloride turn Dutch metal to a green, chalky-bronze patina. Examples of patination. Copper-leaf panel (left) was treated with sodium sulfide; silver panel (center) was treated with potash sulfurated; Dutch metal leaf (right) was treated with ammonium chloride and cupric nitrate.

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 color 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.

Patina A was achieved mainly using copper (II) nitrate to give blue-green shades over a dark background made with recipe B. The Raman spectra collected in different points regularly showed bands.

Cupric Nitrate 300 grams. Distilled Water 1000 ml (fill to 1000 ml level) Photo-flo* 1-2 drops (wetting agent) *One can substitute household liquid detergent or 1-4 drops methyl alcohol. To make up, place the cupric nitrate in a container, pour in water to the 1000 ml level, add the wetting agent and shake until the cupric nitrate is dissolved.

Cupric Nitrate is commonly used over the top of a base patina such as Traditional Liver of Sulfur or Ferric Nitrate Patinas to add more depth and contrast to the finish. Powder Blue is a cold patina for bronze, brass, copper, and the Metal Coatings. This patina results in a stable opaque finish close to a bright ocean blue.

These spectra are quite similar; this is probably due to the employment of copper nitrate for the production of these patinas . In particular, the main characteristic peaks of copper nitrate hydrated (Cu 2 (NO 3)(OH) 3) can be observed at 3541 cm −1, 3420 cm −1, 1420 cm −1, 1340 cm −1, 1046 cm −1, 880 cm −1, 665 cm −1, and 507 cm.

Artificial patination is mostly based on empirical recipes for which the result is difficult to forecast. Little is known about the final corrosion compound formed on the patinated object. Therefore, different patinas based on copper nitrate—an ingredient recurrent in numerous references—were realized according to traditional recipes.

Hot patinas are generally easier to control and apply to large, smooth, vertical surfaces than cold patinas, Baxter says, although the process is not trivial.. And cupric nitrate from a.
