Oil on copper painting is the process of creating artworks by using oil paints with copper as the substrate. This is sometimes referred to as "copper as canvas" because canvas is the most well known surface material used for oil paintings.
Oil on copper paintings were prevalent in the mid sixteenth century in Italy and Northern Europe. [1] The use of copper as a substrate for an oil painting dates back to Medieval times. [2] The Flemish masters and other artists including Jan Breughel the Elder, Claude, El Greco, Guido Reni, Guercino, Rembrandt, Carlo Saraceni, Ambrosius Bosschaert II, Copley Fielding and Vernet painted on copper. They favored copper for its smooth surface which allowed fine detail, and its durability. Copper is more durable than canvas or wood panel as a support for oil painting, as it will not rot, mildew or be eaten by insects. Contemporary painters also use copper as a base for paintings, some of them allowing the metal or patina to show through. [3] [4] [5] [6]
The old masters prepared the copper for painting first by rubbing it with fine pumice abrasive. The copper surface was then treated with garlic juice which is believed to improve adhesion of the paint. Finally a white or grey ground layer of oil paint was applied as a primer. After drying the copper panel was ready for the artist to begin painting. Later artists used the patina process, in which the copper is oxidized with the use of various acidic solutions, as part of the art work itself. The resulting patina or verdigris includes darkening of the metal, green and blue tones, depending on the chemical solution used. Patina is characterized by beautiful variated patterns and textures which occur on the metal's surface. [6] [7] [8]

Oil painting is a painting method involving the procedure of painting with pigments with a medium of drying oil as the binder. It has been the most common technique for artistic painting on canvas, wood panel or copper for several centuries, spreading from Europe to the rest of the world. The advantages of oil for painting images include "greater flexibility, richer and denser color, the use of layers, and a wider range from light to dark". But the process is slower, especially when one layer of paint needs to be allowed to dry before another is applied.
Tempera, also known as egg tempera, is a permanent, fast-drying painting medium consisting of pigments mixed with a water-soluble binder medium, usually glutinous material such as egg yolk. Tempera also refers to the paintings done in this medium. Tempera paintings are very long-lasting, and examples from the first century AD still exist. Egg tempera was a primary method of painting until after 1500 when it was superseded by oil painting. A paint consisting of pigment and binder commonly used in the United States as poster paint is also often referred to as "tempera paint", although the binders in this paint are different from traditional tempera paint.
Printmaking is the process of creating artworks by printing, normally on paper, but also on fabric, wood, metal, and other surfaces. "Traditional printmaking" normally covers only the process of creating prints using a hand processed technique, rather than a photographic reproduction of a visual artwork which would be printed using an electronic machine ; however, there is some cross-over between traditional and digital printmaking, including risograph.
A palette knife is a blunt tool used for mixing or applying paint, with a flexible steel blade. It is primarily used for applying paint to the canvas, mixing paint colors, adding texture to the painted surface, paste, etc., or for marbling, decorative endpapers, etc. The "palette" in the name is a reference to an artist's palette which is used for mixing oil paint and acrylic paints.
Baroque painting is the painting associated with the Baroque cultural movement. The movement is often identified with Absolutism, the Counter Reformation and Catholic Revival, but the existence of important Baroque art and architecture in non-absolutist and Protestant states throughout Western Europe underscores its widespread popularity.
Gesso, also known as "glue gesso" or "Italian gesso", is a white paint mixture used to coat rigid surfaces such as wooden painting panels or masonite as a permanent absorbent primer substrate for painting. It consists of a binder mixed with chalk, gypsum, pigment, or any combination of these.
Giovanni Francesco Barbieri, better known as (il) Guercino, was an Italian Baroque painter and draftsman from Cento in the Emilia region, who was active in Rome and Bologna. The vigorous naturalism of his early manner contrasts with the classical equilibrium of his later works. His many drawings are noted for their luminosity and lively style.
Impasto is a technique used in painting, where paint is laid on an area of the surface thickly, usually thick enough that the brush or painting-knife strokes are visible. Paint can also be mixed right on the canvas. When dry, impasto provides texture; the paint appears to be coming out of the canvas.
Patina is a thin layer that variously forms on the surface of copper, brass, bronze, and similar metals and metal alloys, or certain stones and wooden furniture, or any similar acquired change of a surface through age and exposure.
Guido Reni was an Italian painter of the Baroque period, although his works showed a classical manner, similar to Simon Vouet, Nicolas Poussin, and Philippe de Champaigne. He painted primarily religious works, but also mythological and allegorical subjects. Active in Rome, Naples, and his native Bologna, he became the dominant figure in the Bolognese School that emerged under the influence of the Carracci.
Francesco Albani or Albano was an Italian Baroque painter of Albanian origin who was active in Bologna, Rome, Viterbo (1609–1610), Mantua (1621–1622) and Florence (1633).
Verdigris is a common name for any of a variety of somewhat poisonous copper salts of acetic acid, which range in colour from green to a bluish-green depending on their chemical composition. Once used as a medicine and pharmaceutical preparation, verdigris occurs naturally, creating a patina on copper, bronze, and brass, and is the main component of a historic green pigment used for artistic purposes from antiquity until the late 20th century, including in easel painting, polychromatic sculptures, and illumination of maps. However, due to its instability, its popularity declined as other green pigments became readily available. The instability of its appearance stems from its hydration level and basicity, which change as the pigment interacts with other materials over time.
A panel painting is a painting made on a flat panel of wood, either a single piece or a number of pieces joined together. Until canvas became the more popular support medium in the 16th century, panel painting was the normal method, when not painting directly onto a wall (fresco) or on vellum. Wood panels were also used for mounting vellum paintings.
Willem van Herp (I) or Willem van Herp the Elder (variations on first name: 'Guilliam', 'Gilliam' and 'Guillaume') (c. 1614 in Antwerp – 1677) was a Flemish Baroque painter specializing in religious paintings and small cabinet paintings of "low-life" genre scenes. He operated a large workshop and through his good connections with Antwerp art dealers helped spread the Flemish Baroque style internationally.
Bronze disease is an irreversible and nearly inexorable corrosion process that occurs when chlorides come into contact with bronze or other copper-bearing alloys. It can occur as both a dark green coating, or as a much lighter whitish fuzzy or furry green coating. It is not a bacterial infection, but the result of a chemical reaction with the chlorides that usually occurs due to contamination of the bronze object by saltwater or from burial in specific types of soil where chloride salts are present. If not treated, complete destruction of the affected artifact is possible. Treatment is very difficult, costly and not always effective. Transfer of chlorides from the contaminated artefact to other artefacts can spread the condition.
The Galleria Spada is a museum in Rome, which is housed in the Palazzo Spada on Piazza Capo di Ferro. The palazzo is also famous for its façade and for the forced perspective gallery by Francesco Borromini.
Kadar Brock is an American artist living and working in Brooklyn, New York. He received his BFA from Cooper Union School of Art in New York City in 2002. His abstract paintings explore history, personal psychology, materials and surface.
Imperial Fritillaries in a Copper Vase is an oil painting on canvas created by the Post-Impressionist painter Vincent van Gogh in Paris, 1887. The painting is now part of the collection of the Musée d'Orsay in Paris, France. This work was made at a time of the life of Van Gogh when he first encountered influences from Impressionists and became aware of light and color, implementing it in his paintings. This painting presages some of his most famous subsequent works, and stands out from other still lifes because of the implementation of mixed techniques and complementary colors.
Green pigments are the materials used to create the green colors seen in painting and the other arts. Most come from minerals, particularly those containing compounds of copper. Green pigments reflect the green portions of the spectrum of visible light, and absorb the others. Important green pigments in art history include Malachite and Verdigris, found in tomb paintings in Ancient Egypt, and the Green earth pigments popular in the Middle Ages. More recent greens, such as Cobalt Green, are largely synthetic, made in laboratories and factories.
In visual arts, the ground is a prepared surface that covers the support of the picture and underlies the actual painting. Occasionally the term is also used in a broad sense to designate any surface used for painting, for example, paper for watercolor or plaster for fresco.
