Historical Pigment: Brun Rouge

10/31/14 12:00 PM

Roger de Piles' Les Élémens de Peinture PratiqueThe palette described by Roger de Piles in his 17th century painting manual, Les Elémens de Peinture Pratique, describes a pigment in French, brun rouge. The basic palette described by de Piles comprises these colors: 1. White lead. 2. Yellow ocher. 3. Brown red. 4. Lake. 5. Stil de grain. 6. Green earth. 7. Umber. 8. Bone or ivory black. My interest is to provide hues that closely resemble the colors found on this 17th century palette, but not only the hues, the undertones and the paint consistency. It is rather easy to mimic a hue with a combination of pigments, but much more difficult the undertones and nearly impossible the paint consistency. The latter can only be done successfully by using the same pigment, at least as far as we can determine from literary sources.

Detail of a painting by Henry Cliffe, painted in 1959, shows severe cracking and interlayer cleavage in paint containing lead white and zinc white.A paper written by scientists at the Smithsonian’s Museum Conservation Institute exposes long-term problems with zinc white in oil paint. The report “The Chemical and Mechanical Effects of Pigments on Drying Oils” describes the highlights of a 28-year study on the stability and strength of oil paint films. The results are revealing and have important implications for artwork made with artists’ oil paints containing zinc white.

The paper by Marion Mecklenburg and Charles Tumosa examines the drying of different drying oils, traditional pigments and commercially prepared artists’ oil paints. It also studies the differences of the effects of pigments on the long-term stiffening and film formation of paints. For the study, different pigments were ground in different oils, applied to polyester films and then stored in a controlled environment. Over the years, the paints were removed from the polyester film and tested mechanically as unsupported thin films.

Fred Wessel Jacqui (Corona)How Fred Wessel uses Rublev Colours Aqueous Pigment Dispersions made by Natural Pigments along with dry pigment powders in his tempera paintings. The dispersions eliminate the step of dispersing pigments in water, allowing him to spend more time at the easel and less with the muller and grinding surface: “I use Rublev Colours Aqueous Pigment Dispersions to compliment the powdered pigments that I use to make my tempera paintings. Unless my powdered pigments are super-fine, I’ll need to grind them to a fine paste with water. The dispersions eliminate this step, allowing me to spend more time at my easel and less with my muller.”

Roger de PilesIn the 17th century, Roger de Piles described in precise detail the flesh tone palette used by nearly every artist of that time in his seminal treatise, Les Élémens de Peinture Pratique. This painting manual influenced artists for several hundred years and established the current practice of setting a limited palette and a rational approach to painting portraits among the greatest artists of that period. In this article, we translate four chapter from the original 1684 French manual and explain how contemporary artists can set the limited 17th century palette for flesh tones using Rublev Colours® Artists’ Oils.

Ceracolors--Water-soluble wax paintIt’s not often that a brand-new fine art medium comes along. Ceracolors is a new artist-grade paint made from quality pigments in a water-soluble wax binder. Although made from wax, Ceracolors are not encaustic paints in that they do not require heat, solvents or mediums.

Oleogel Road Test

10/8/13 12:00 PM

The Artist's Magazine October 2013Oleogel was featured in Rob Anderson's Road Test column in the October 2013 issue of The Artist's Magazine. Rob writes about Oleogel: “What exactly does adding Oleogel to paint do? Oleogel maintains the body of the paint—say goodbye, in other words, to drippy paint—at the same time it increases the paint’s transparency. The medium is versatile enough that it can be used for a thick impasto and also for glazing. The fact that this medium is this versatile is something I’ve never seen before. In my experience, a medium typically is only good for one thing, either glazing or helping to extend and thicken the paint, but not both. All in all, I had a very positive experience using Oleogel. The increase in fluidity and simultaneous control were wonderful surprises. I plan on continuing to use the medium, making it a part of my painting process.”

Purple OcherOchers are natural iron oxide earths that are found in many parts of the world. They are among the most lightfast and stable pigments used in the arts. Iron oxide pigments produce a wide range of colors, from black through shades of purple and red in the anhydrous oxides to yellow, orange, and brown in the oxide hydroxides. While it is the iron oxides that produce the colors, other minerals—such as quartz and clays, for example—are also present. Iron oxides have high tinting strength, and strongly colored earths that are suitable as pigments may contain a relatively low concentration of iron minerals compared to the concentration of the other minerals. The weight percentage of iron oxide in these earth pigments vary widely from as low as 10% to upper amount of 97% with clay and quartz accounting for the remainder.

Six Ways I Use Oleogel

9/30/13 12:00 PM

Kate Stone paintingI push Oleogel on all my friends and I've even done time for selling it in a schoolyard. After using it regularly for the past year and half I've come up with a variety of uses for it and I thought I might share them.

For those who haven't come across this term before,"couche" is French for "paint layer," and in the context of classical technique, a couche is a thin layer of oil that you spread over an area that you are about to work on, usually an area that you are going to bring to a finish with fine detail and blending. The oil makes the fresh paint flow onto the surface better (great if you're working with tiny amounts of paint on little itty bitty brushes) and at the same time saturates the old paint layer so that you can match your colours perfectly. Snort. As if anyone manages that.
