Today, lamp black is procured by the imperfect combustion of oils obtained in coal-tar distillation. A fine, light, fluffy powder is derived by collecting the soot from the burning oil. It is the most familiar of the pure carbon black group of pigments.
What is the source of lamp black?
Source. Lamp black, a deep black pigment consisting of amorphous carbon in a very fine state of division, is obtained by the imperfect combustion of highly carbonaceous substances. When resins, resinous woods, fatty oils and fats, paraffin and paraffin oil, or coal-tar oils, are burnt with an insufficient supply of air,...
Can lamp black be used in oil paint?
Lamp black is a permanent color for all uses on the artist's palette. It is compatible with all other pigments, and can be used with good results in all mediums. However, it is not generally recommended for use in oils, because carbon is an anti-oxidant that greatly slows the drying time of oil paint.

The Preparation Of Lampblack
This section is from the book " Cassell's Cyclopaedia Of Mechanics ", by Paul N. Hasluck. Also available from Amazon: Cassell's Cyclopaedia Of Mechanics.
The Preparation Of Lampblack
In producing the various grades of lampblack, soot oil, which is the last oil obtained in the distillation of coal tar freed from naphthaline as far as possible, is burned in a special furnace. In this furnace is an iron plate, which must always be kept glowing, and upon this plate the soot oil trickles from a vessel fixed above.
How is lamp black obtained?
Lamp black, a deep black pigment consisting of amorphous carbon in a very fine state of division, is obtained by the imperfect combustion of highly carbonaceous substances. When resins, resinous woods, fatty oils and fats, paraffin and paraffin oil, or coal-tar oils, are burnt with an insufficient supply of air, a considerable part of the carbon they contain may be deposited in the form of soot. This soot is not, however, pure carbon, but retains variable proportions of the tarry products of imperfect combustion; these tarry products impart to lamp black a more or less pronounced warm brownish hue, except in the cases in which it has been prepared by processes specially designed to remove the tarry products. Today, lamp black is procured by the imperfect combustion of oils obtained in coal-tar distillation. A fine, light, fluffy powder is derived by collecting the soot from the burning oil. It is the most familiar of the pure carbon black group of pigments.
