Lampblack

Lampblack consists almost entirely of amorphous carbon in an extremely fine state of division. It is formed by burning an oil, or other highly carbonaceous material, in a limited supply of air, and collecting the soot formed as a product of the incomplete combustion. It is very largely used as a pigment, and in the manufacture of printing and Indian inks.
