Made from pigment mixed with nondrying oil and a wax binder, the first oil pastels were invented by the Osaka-based company Sakura in 1924 for use in Japanese schools. While oil pastels never caught on with Japan’s educators, they interested artists—including Pablo Picasso, who collaborated with the French manufacturer of art supplies Sennelier to develop a higher-quality version of Sakura’s product. Sennelier’s launch of their oil pastel in 1949 was followed Holbein’s in the 1980s and Caran d’Aches’s in the 1990s.
A cleaner medium than chalk pastels, but still softer and more blendable than either colored pencils or crayons, oil pastels are a great tool for both sketching and making finished pieces. Thinned with oil or solvents, they can also be used for painting. A concern with oil pastels is that they never completely dry and should ideally be treated with a fixative or framed behind glass. But they make up for that in ease of use, workability, and vivid color.
1. Sennelier Oil Pastels
Our top recommendation in this category of art materials is also the top of the line, because oil pastels tend to be fairly affordable compared to many art mediums. And, if you can afford them, Sennelier oil pastels—buttery, blendable, and with a higher pigment-to-binder ratio than any other brand—are the best you can buy. With a storied history (Picasso asked this Paris-based purveyor of art supplies to make a line of oil pastels for him in the late 1940s), Sennelier remains the gold standard for oil pastels. This set comes with Sennelier’s 48 basic colors with another 24 colors suitable for specific genres, including portrait and landscape drawing. Because Sennelier’s complete range of 120 colors can also be purchased individually, this set balances economy with sufficiency. Be aware, though, that Sennelier uses top-quality pigments, including some, such as cobalts and cadmiums, that are now known to be toxic. Wash your hands after use.
2. Caran d’Ache Neopastel Oil Pastels
Somewhat less expensive, but also a great choice, Caran d’Ache oil pastels are likewise strongly pigmented and easy to blend. Slightly harder than the other top brands, Caran d’Ache pastels are also renowned for their opacity. Unlike Sennelier’s oil pastels, these are certified by the Art & Creative Materials Institute Inc. (ACMI) as nontoxic; their colors do not include cadmium, cobalt, or other mineral pigments requiring a warning under California law. As with Sennelier, you can buy Caran d’Ache oil pastels individually, but with this box of 96, you probably won’t need to.
3. Mungyo Gallery Artist’s Soft Oil Pastels
Creamy, highly pigmented, and less crumbly than student-grade brands, the Mungyo Gallery Artists’ oil pastels are professional-quality pastels at student prices. Like Caran d’Ache, they are certified nontoxic. A warning for consumers: Mungyo Gallery Artists’ Soft Oil Pastels are not the same as their student-grade Gallery Oil Pastels and the difference is not always made clear in product listings.
Technically, a wax crayon rather than an oil pastel, and falling somewhere in between in terms of feel, Caran d’Ache Neocolor II Artist Crayons are an option for those who don’t want to use spirits or oils as thinners. Professional quality, lightfast, and easily worked when dry, they can be thinned and blended with water. Like all water-soluble pastels, these tend to leave a faint line when washed—don’t expect them to be as fully dissolvable as watercolors but treat them as you would their oil-based counterparts.
5. Sakura Cray-Pas Espressionist Oil Pastels
From the makers of the original oil pastel, Sakura’s Cray-Pas Expressionist pastels have a high wax content, making them firmer and less blendable than other oil pastels. Still, they go on smoothly and are nontoxic and lightfast. While they come in a limited range of colors, they’re a great quality oil pastel at a great price, suitable for older children, students, and even professionals looking for a harder pastel for detail work.
