R&F Pigment Sticks put the paint directly in your hand, eliminating the separation between brush and surface. These are true oil colors, handmade in small batches with just enough wax added to shape them into a stick. Made with three simple, traditional materials—natural bee and plant waxes, linseed oil, and pigments of unmatched purity—their lipstick-soft consistency invites spontaneous mark making and results in strong, durable films.

With a range of 96 colors, R&F Pigment Sticks offer a liberating alternative to the limited palettes of traditional printmaking or tube paints. Use them on their own or mix with traditional oil colors. Thin them with turpentine or mineral spirits, or work them directly into stand oil, linseed oil, alkyd mediums, or resin gels. Whether you're sketching loosely on canvas or building up rich layers, Pigment Sticks deliver a direct, tactile experience that bridges the gap between drawing and painting.

They work on any surface suitable for traditional oil painting—sized canvas, paper, or panels. For a faster-drying, matte finish, try more absorbent surfaces like clay-coated papers. Once fully dry, Pigment Stick artwork can be varnished just like any oil painting.

Small sticks are 38 ml—about the same as a standard tube of artists' oil paint. Medium sticks are 100 ml. Large sticks are 188 ml.

Cobalt Violet

Pigment code
PV14
Type
inorganic
Chemical name
cobalt phosphate
Chemical formula
Co3(PO4)2
Properties
Cobalt Violet is a pure hue that cannot be mixed from other colors. It is cool in its masstone, chemically stable, and semi-opaque. It has a weak tinting strength and is generally offered in a bluish and a reddish-violet shade. Cobalt Violet can be quite expensive, so it is used mostly as a top coat color. It is compatible with all painting media, but its light variety can change in oil form. It grays down considerably when mixed with white. Manganese Violet is a less costly substitute for the bluish variety of Cobalt Violet.
Permanence
Cobalt Violet has excellent permanence, and its lightfastness makes it more desirable than older organic dye violets.
Toxicity
Cobalt Violet is highly toxic by both ingestion and inhalation, particularly in dry pigment form. However, much of the material presently used to make paints of this color is non-toxic cobalt phosphate.
History
Cobalt comes from the Middle High German word kobolt, an underground goblin, because miners thought cobalt harmed silver ores. Cobalt Violet was the first real violet pigment and was described by Salvetat in 1859. The light variety of this pigment, developed in Germany earlier in the 19th century, was particularly poisonous due to its arsenic content. Cobalt Violet hues were the only permanent bright violets available to artists until the 1950s.
