History

This organic pigment has been called Van Dyke Brown because it is so similar to the brown used by Flemish painter Anthony van Dyck, although it is in fact a modern synthetic pigment. In addition to its use in art, it has been used as a pigment for coloring plastics and synthetic fibers.

Pigment Name

PO49-Quinacridone Gold

Pigment Type

organic, quinacridone

Chemical Formula

Properties

Quinacridone Gold is a transparent yellow-orange pigment. Quinacridone pigments have relatively low tinting strength in general. For this reason, quinacridone colors are often expensive, because more pigment is required in the formulation.

Permanence

Quinacridone Gold has very good lightfastness.

Toxicity

History

Quinacridone Gold, a color developed for the automotive industry, is no longer being manufactured. Some color producers still have stocks of the pigment.

Pigment Name

PBk9-Ivory Black

Pigment Type

charred animal bone

Chemical Name

carbon + calcium phosphate

Chemical Formula

C + Ca3(PO4)2 or C x CaPO4

Properties

Ivory Black is a cool, semi-transparent blue-black with a slight brownish undertone and average tinting strength. It mixes well with any color, and creates a range of dull greens when mixed with yellow. It has good properties for use in oil, can be slow to dry in oil form, and should never be used in underpainting or frescoing. Ivory Black is denser than Lamp Black.

Permanence

Ivory Black is very lightfast and has good permanence, though it is considered the least permanent of the major black pigments.

Toxicity

Ivory Black has no significant hazards.

History

Ivory Black is a carbon based black first named as Elephantium, and described in the 4th century BCE as produced by heating ivory scraps in clay pots to reduce the ivory or bone to charcoal. The deviation in names is because the more expensive varieties of this pigment were made by burning ivory, and the less expensive ones by burning animal bone. In the 19th century, the name Ivory Black was finally permitted to be applied to Carbon Black pigments made from bone. True Ivory Black is rare in modern times due to the protection of ivory, and the synthetic variety produced today was discovered in 1929. Bone Black is produced as an industrial pigment.
