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.

Red Iron Oxide

Pigment code
PR101
Type
earth, synthetic
Chemical name
iron oxides (synthetic), iron oxide, silica, alumina, lime, and magnesia or hydrated iron oxide
Chemical formula
Fe2O2 or Fe2O3 x H2O
Properties
Red iron oxide varies in hue and transparency, depending on hydration and slight impurities. Indian Red is a slightly duller, deep brick hue with a bluish undertone. It is very dense and opaque, with excellent tinting strength and covering power. It is dependable when mixing with all other permanent pigments and yields good flesh tints when mixed with Zinc White. It is the synthetic version of PR102, which is a pigment made from earth reds, or natural red iron oxides, and the names applied to PR101 and PR102 often overlap. The synthetic red iron oxides have mostly replaced natural red iron oxides and are brighter, stronger, finer, and more permanent. Indian Red is the highest grade bluish shade. Light Red, English Red, and Venetian Red are yellowish shades. Mars Violet is a dull and subdued bluish or purplish oxide.
Permanence
Red iron oxide is very lightfast with excellent permanence.
Toxicity
Red iron oxide has no significant hazards.
History
Natural red iron oxide comes from the mineral ore hematite, called bloodstone by the ancient Greeks from the word hema, meaning blood. It is one of the oldest pigments, has been used by every major civilization, and was an important mineral for medieval alchemists. It was not widely used in artists' materials until the 17th century and was not produced in large quantities until the 18th century.
