BLACK PIGMENT. A fine lamp-black is obtained by the combustion of a thick torch of coal-gas, supplied with a quantity of air adequate to burn only its hydrogen. In this case, the whole of its carbon is deposited in the form of a very fine black powder of extreme lightness. This black is used in making better qualities of printer's ink.
