Over a long period of time the copper reacted to the local climate by oxidizing, producing the protective green patina seen today. Few remember seeing its original copper color. This notable New York harbor landmark is known for its bright green patina. The most famous example of copper patina is the Statue of Liberty. Likewise, American western artist Frederick Remington, used patinas on his twenty-two famous statues depicting cowboy and western American life. Sculptor, Auguste Rodin used patinas on many of his bronze pieces. The processes vary by artist, as do the choice of materials, thus, adding a sense of mood and drama to an object, to enhance and highlight detail or to accelerate the ageing process.Īrtists have been using patina since, at least the 1800s. The work is then dried by air, heating, or baking, and is often sealed with a spray fixative (usually a clear lacquer), a wax, or a varnish. These solutions can be sprayed, brushed, dipped, dabbed, or wiped onto the metal, which is usually cleaned in an acid solution or on a finishing wheel prior to (and often during and after) application. Today, to patinate their work, jewelry artists employ a huge palette of homemade recipes, commercial products, and methodologies. Though the history of metalworking is relatively young in Japan, Japanese craftsmen have developed alloys and the art of patination further than any other metalworking culture in the world. Their metallurgy probably originated in China and Korea, but the development and use of non-ferrous copper-based alloys, particularly during the 15th and 16th centuries, was unrivalled. The rich history of Japanese patinas is the result of hundreds of years of experimentation, innovation and tradition. The finest tradition of metal coloring and patination was that of the Japanese. Ancient artifacts of earlier periods have been diligently collected and studied and have kindled a desire to imitate the natural patination as a finishing process for contemporary work. Interest in metalworking has had many revivals of earlier periods, such as classicism, but more so in renaissance Italy and the Chin dynasty in 12th century China. The meaning of the word is relatively recent and it is believed originated in the mid-18th century when the field of archeology had begun to develop, along with admiration of the colored corrosion products. Patina today is most commonly used to refer to the green corrosion products that form in time on copper and copper alloys such as bronze when it is exposed to the open air or to burial conditions. It was considered the brightest green pigment available. It was called verdigris which literally means “green of Greece,” but in modern times it is often shortened to Verde or Verdi. ![]() In history, impermanent patina induced by seawater was used in excess by Greek artists as a colorant. Sometimes referred to as natural toning, a patina was once only achieved with the passing of time. Patina results when the surface of a metal is altered by the effects of the atmosphere, causing gradual changes which initially tarnish the metal with an uneven coloring eventually causing the whole surface to convert into a basic mineral product typically green in color. Because such trays became venerable and precious for their association with the body of Christ, they were preserved over long periods of time, thus, developing the signs of age: that particular mottled green surface of old bronze, along with the signs of use and wear. The English word “patina” derives from the Greek term for dish and refers to the tray, often bronze, which was used to distribute the host during the eucharist. ![]()
