Too Pretty to Touch

“It’s so pretty, I’m scared to touch it.” It’s a sentence I’ve heard from many an intimidated artist when faced with a newly purchased and admittedly gorgeous copper panel. The pristine surface does fingerprint if you touch it and wait a few days. Back in the day, I shipped new panels with white cotton gloves so when you unwrap them, you can avoid these little imperfections. But I’ll let you in on a big secret, oil and copper belong together. Oil creates a bond and protective layer to the copper surface.

When I paint on copper, I am about as rude to my panels as anyone can imagine. I stuff it in my paint bag, let the surface get dirty, I touch it, and if I make mistakes and the mistake dries, I sand it back down to copper. I couldn’t be more irreverent to these perfect surfaces I paint on. Why, because I paint on them. And when I leave a bit of light or some exposed copper coming through, I’ve yet to have any noticeable imperfection. Besides, it’s our little imperfections that make us beautiful, right?

“Fine, Ann, fine. But what about if we want a large area of gorgeous, perfect shiny copper in our painting?” Well, good news. You can handle the unpainted panel with gloves. And you only have to sing MC Hammer’s “Can’t Touch This” the first time. If the panels are already tarnished or corroded, they can be cleaned by scrubbing any stubborn stains with Rublev Colours Copper Stain Remover and then rinsing with water and drying with a soft cloth. You can then apply a corrosion inhibitor available from Natural Pigments, Rublev Colours Copper Rinse. Spray directly over the clean, dry panel (rub it with a cotton ball if you want to avoid a slight haze), and then you have a greatly extended time to complete your painting without any concern for oxidation. You can also seal the beautifully finished work and any exposed copper to protect it from oxidation with Conservar Acrylic Varnish that Natural Pigments has specifically developed for use on copper.

Fear is my least favorite emotion, and I think the biggest block to creativity. Fear copper no more and shine on you beautiful people.

Painting on Copper—Origins

The practice of painting in oil on copper had its origins in the sixteenth-century. What is not well understood is where in Europe the practice began. In Lives of the Most Excellent Painters, Sculptors, and Architects (Italian: Le Vite de’ più eccellenti pittori, scultori, e architettori) Giorgio Vasari (1511–1574) reported that Sebastiano del Piombo (1485–1547) made paintings on silver, lead and copper, likely in the first half of the fifteenth century. Among the first Italian painters to paint on copper was Antonio Correggio (1489–1534) who painted a ‘Penitent Magdalene’ on copper formerly in Dresden Gemäldegalerie but now lost. It wasn’t until the 1560s, however, that copper supports gained wider usage in Italy when Vasari, Agnolo Bronzino and Alessandro Allori painted works on copper for Francesco I de’ Medici in Florence.

That Northern European artists working in Italy adopted this practice and returned home with this new support is corroborated by biographer Karel van Mander (1548–1606). Van Mander writes in ‘Life of Bartholomeus Spranger, painting artist from Antwerp’ in his Book of Painters (Dutch: Schilder-Boeck) while in Rome Spranger (1546–1625) executed a ‘Last Judgement’ on copper, dated about 1570. In the ‘Life’ of Pieter Vlerick (1539–1581) Van Mander mentions that there was a painter named Michel Gioncquoy, who came from Rome and had painted many pictures on copper. In the ‘Life’ of Hans Rottenhammer (1564–1623) Van Mander mentions, that when Rottenhammer came to Rome he started painting on copper, ‘as is the working-method of the Netherlandish painters’.

What is clear from literature is that painting on copper got its start in the sixteenth century and became widespread in Europe in the latter half of the century. What is not established is where the practice of painting on metal supports got its start. Whether it began in Italy, and especially in Rome, as Vasari reports in the biography of Sebastiano del Piombo, or in the Netherlands as Van Mander mentions was ‘the working-method of the Netherlandish painters’ is not certain.

Surviving works on copper perhaps give us a clue because they indicate that copper was mostly used in the north, especially by Netherlandish and German painters. One of the most prolific and talented painters to have used a copper support is Joachim Wtewael (1566–1638). Wtewael’s work typifies the advantages of copper’s hard smooth surface to create highly illusionistic, brilliantly colored images, filled with minute detail, where brushstrokes could be made nearly invisible.

The new support found a new outlet for its expansion in Antwerp. Jan Brueghel the Elder (1568–1625) returned to his native Antwerp in 1595 to practice painting techniques that he had learned in Rome. What is remarkable is that between 1593 and his death in 1625, Brueghel made approximately 400 paintings, of which some 165 were on copper.

During his time in Rome, Jan Brueghel became acquainted with Paul Bril (1554–1626) and Hans Rottenhammer (1564–1625). Paul Bril was a landscape painter from Antwerp who had moved to Rome. Rottenhammer was a German painter of small highly finished cabinet paintings on copper. Brueghel collaborated with both Bril and Rottenhammer and was influenced not only by their aesthetic work but also the practice of painting on copper.

Brueghel’s collaborations with Rottenhammer began in Rome around 1595 and ended in 1610. Initially when the artists both lived in Venice, their collaborative works were executed on canvas, but in their later collaborations after Brueghel had returned to Antwerp they typically used copper. After Brueghel’s return to Antwerp, their procedure was for Brueghel to send the copper plates with the landscape to Rottenhammer in Venice, who painted in the figures and then returned the plates. In a few instances, the process was the other way around.

While in his collaborations with Rottenhammer, the landscapes were made by Brueghel, the roles were reversed when he worked with Joos de Momper (1564–1635) . There are about 59 known collaborations between Brueghel and de Momper making de Momper his most frequent collaborator. Hendrick van Balen the Elder (c. 1573 to 1575–1632) was another regular collaborator with Brueghel.

Antwerp was a burgeoning printing and publishing center in the sixteenth and seventeenth centuries, so it is not surprising that copper plates were not only readily available but affordable. Jørgen Wadum’s study of Antwerp coppersmiths, and the relative costs of panels, artists’ materials and paintings on copper revealed that prices for copper plates were roughly similar to those for wooden panels.

Comparatively few copper printing plates were used as a support for oil painting. In an examination of 325 paintings on copper from the sixteenth to the eighteenth centuries by Isabel Horovitz, 50 had qualities required for printmaking.

Most paintings on copper were small when compared to other supports, the majority no larger than 15 3/4 by 23 5/8 inches (40 x 60 cm). There were notable exceptions, such as the painting on copper ‘Archduke Leopold Willem in his Painting Gallery in Brussels’, which measures 41 3/4 x 50 3/4 inches (104.8 x 130.4 cm), by Brueghel’s son-in-law, David Teniers the Younger (1610–1690).

The practice of painting on copper was widespread in Europe in the sixteenth and seventeenth centuries. Northern European artists, especially in Netherlands and Germany produced the bulk of these paintings. By 1650 the popularity of copper supports for oil painting began to wane, until the eighteenth century copper plates were seldom used for painting.
