The black dresses and high hats of the gentlemen in Manet's Music in the Tuileries are painted in ivory black. [12] [13] Ivory black was formerly made by grinding charred ivory in oil. Nowadays ivory black is considered a synonym for bone black. Actual ivory is no longer used because of the expense and because animals that are natural sources ...
Carbon black (with subtypes acetylene black, channel black, furnace black, lamp black and thermal black) is a material produced by the incomplete combustion of coal tar, vegetable matter, or petroleum products, including fuel oil, fluid catalytic cracking tar, and ethylene cracking in a limited supply of air.

Ivory black, also known as bone char, was originally produced by burning ivory and mixing the resulting charcoal powder with oil. The color is still made today, but ordinary animal bones are substituted for ivory. Mars black is a black pigment made of synthetic iron oxides. It is commonly used in water-colors and oil painting.
Carbon black particle size is between 10 and 100 nm, while the surface particle size is between 20 and 1,500 m 2 /g. Generally speaking, small carbon black particles with a high surface area are darker, have higher viscosity and lower wettability, are harder to disperse, retain greater conductivity and absorb UV radiation well.

In color theory, a shade is a pure color mixed with black. It decreases its lightness while nearly conserving its chromaticity. Strictly speaking, a "shade of black" is always a pure black itself and a "tint of black" would be a neutral gray. In practice, many off-black colors possess a hue and a colorfulness (also called saturation).
Carbon black is a term for the industrial production of powdery carbonaceous matter which has been underway since the 19th century. Carbon black is composed almost entirely of elemental carbon. Carbon black is not found in regular soot - only in the special soot that is intentionally produced for its manufacture, mostly from specialised oil ...
