The Deep Dive
Ivory black is a carbon-based black pigment traditionally made by charring animal material, historically ivory or horn, today almost exclusively bone, in a low-oxygen kiln until only carbonized residue remains. Chemically it is not pure carbon like lamp black or charcoal but an impure carbon pigment, typically around 10 to 20 percent carbon bound up with roughly 84 percent calcium hydroxyapatite (bone mineral) plus smaller amounts of calcium carbonate and magnesium phosphate; this mineral content gives it a denser, finer-grained, slightly bluish-black character distinct from purely carbon blacks such as lamp black or vine black. The pigment is one of the oldest in continuous use, employed since prehistoric times and still manufactured and sold today, its name deriving from the Medieval Latin eborium ("ivory"). Genuine ivory-derived black became increasingly rare as elephant ivory grew scarce and ethically fraught, and by the 19th and 20th centuries "ivory black" on the market was, and remains, produced from charred cattle bone rather than actual ivory, despite retaining the historical name. It found extensive use across egg tempera, oil, and watercolor painting due to excellent lightfastness (rated ASTM I) and full compatibility with other pigments. Rembrandt used it heavily for dark clothing and shadow glazes in 17th-century portraiture, and it remained a studio staple well into the modern era, identified for instance in the black clothing of figures in Edouard Manet's Music in the Tuileries Gardens (1862).
Symbolism
Black carbon pigments carry some of the oldest and most universal symbolic weight of any color family, tied across cultures to mourning, solemnity, the underworld, and the void, and ivory and bone black's especially dense, velvety darkness made it the preferred vehicle for rendering the black garments of mourning, clerical dress, and magisterial authority in European portraiture from the 17th century onward. Rembrandt's repeated use of bone black for the somber black clothing worn by Dutch burghers and their wives reflects the Calvinist Netherlands' sober dress codes, in which unadorned black signified piety and wealth restrained by modesty, a visual code the Dutch merchant elite consciously cultivated in portraiture as a mark of civic respectability. Because it derives from burned animal remains, ivory and bone black also sit within a long, cross-cultural tradition of associating blackness and char with transformation through fire and with mortality itself, the pigment quite literally being the physical residue of a once-living creature reduced to its most permanent, unchanging component.
Pigment history
Bone and ivory black are produced by pyrolysis: animal bone, or historically ivory and horn, is heated in a sealed or low-oxygen kiln, driving off organic material and leaving a carbonized residue that is roughly 10 to 20 percent elemental carbon bound within a mineral matrix of calcium phosphate (hydroxyapatite) and calcium carbonate. This manufacturing method, charring bone rather than the soot-collection method used for lamp black or the wood-charring used for vine black and charcoal, has remained essentially unchanged since prehistory, making ivory and bone black one of the most continuously produced pigments in human history. True ivory black, made specifically from elephant ivory or tusk scraps, was historically the finer and more prized grade, but as ivory became scarcer, more regulated, and ethically unacceptable through the 19th and 20th centuries, manufacturers shifted entirely to charred cattle bone, retaining the traditional "ivory black" name as a trade term even though no ivory is now used. The pigment's stability, deep undertone, and full compatibility with every other pigment class kept it a studio staple through the oil-painting era of Rembrandt, Vermeer, and later Manet, and it remains commercially manufactured and sold by artists' color makers today, still labeled ivory black despite its bone-derived reality.
Notable uses
- Portrait of an 83-Year-Old Woman (1634), Rembrandt van RijnRembrandt rendered the sitter's dress in solid, pure bone black applied directly over the ground layer, with subtle greys achieved by adding small amounts of white.
- Portrait of Philips Lucasz (1635), Rembrandt van RijnRembrandt applied unmixed bone black to the darkest clothing elements and, elsewhere in the painting, incorporated small quantities of blue or red into black mixtures.
- Music in the Tuileries Gardens (1862), Edouard ManetThe black clothing of male figures was painted with ivory black combined with cobalt blue and an orange-brown ochre in places, according to pigment analysis.
- Rembrandt's underdrawing and wash sketches (various works, 1630s-1660s), Rembrandt van RijnNeutron activation autoradiography revealed Rembrandt's widespread use of bone black in initial wash-like sketches applied over the ground layer before painting.
- A Woman Bathing in a Stream (1654) and Portrait of Hendrickje Stoffels, Rembrandt van RijnAlongside bone black, Rembrandt used wood charcoal for a cooler, slightly bluish-black cast in mid-tones and fur accents in these works.
