Webster's Dictionary (GCIDE)

Lampblack \Lamp"black`\, n. [Lamp + black.] The fine impalpable soot obtained from the smoke of carbonaceous substances which have been only partly burnt, as in the flame of a smoking lamp. It consists of finely divided carbon, with sometimes a very small proportion of various impurities. It is used as an ingredient of printers' ink, and various black pigments and cements. [1913 Webster]
