Sennelier Oil Pastels are a benchmark in the art world: lipstick soft, highly pigmented pastels made in France with the same top-quality components found in all Sennelier colors.
Developed in collaboration with Pablo Picasso, they combine pure pigments, an exceptionally pure synthetic binding medium, and pH-neutral mineral waxes to create an oil pastel unlike any other.
Each stick is packed with an extraordinarily high pigment load, giving it superior covering power, exceptional brightness, and a high degree of lightfastness (with the exception of metallic and fluorescent colors).
The balance of wax and binder results in a uniquely rich, smooth texture that allows artists to work with freedom, whether creating thin veils of color or bold, impasto-like strokes.
The binder is inert and non-siccative, meaning it won’t oxidize, crack, or alter over time. Combined with mineral wax, this ensures excellent surface stability and makes blending and layering effortless.

Cobalt Blue
- Pigment code
- PB28
- Type
- inorganic
- Chemical name
- cobalt(II) oxide + aluminum oxide
- Chemical formula
- CoO + Al2O3
- Properties
- Cobalt blue is a semitransparent pigment with low to moderate tinting strength. When it dries, it appears lighter and less saturated. Pigment particles are large and grainy. Differences in how the pigment is ground and mixed lead to considerable differences in its performance among various manufacturers.
- Permanence
- Cobalt blue is absolutely lightfast and extraordinarily stable. The stability of cobalt salts at high temperatures make them the standard for blues used in ceramics and glassware.
- Toxicity
- Cobalt salts are toxic. Avoid respiratory and skin contact. Soluble cobalt may cause irritation and allergic reaction through contact with skin. It is considered a possible carcinogen.
- History
- Since ancient times, smalt blue has been used to color glass and ceramics. Cobalt salts, which give smalt its characteristic blue color, were identified in the 18th century. Techniques for manufacturing Cobalt Blue, a chemically pure salt of cobalt and aluminum oxide, were developed in 1802.

Zinc Sulphide White
- Pigment code
- PW7
- Type
- inorganic
- Chemical name
- zinc sulfide
- Chemical formula
- ZnS
- Properties
- Zinc Sulphide White is a semi-transparent yellowish white pigment. Zinc sulfide and zinc oxide (PW4) are often combined to create a more natural white color. Transparency increases as particle size decreases. When slight impurities are added, zinc sulphide has phospherescent and electroluminescent properties. It is often used to manufacture fluorescent or glow-in-the-dark paints.
- Permanence
- Zinc Sulphide White has excellent permanence and lightfastness.
- Toxicity
- Zinc Sulphide is non-toxic, but ore deposits often contain lead. Traces of lead and other impurities may be present in pigment powders. Ingestion is not recommended.
- History
- Zinc sulfide, when combined with slight impurites, has phospherescent properties. It is often used for "invisible ink" that glows with exposure to ultraviolet light. Zinc sulfide is used in the manufacture of fluorescent paints.
