Text: Lamp Black Synonyms: Carbon Lampblack; Acetylene black; Animal bone charcoal; Lampblack; Fullerene tubes; Carbon soot Designations: Chemical Name: Carbon Chemical Formula: C Description: A finely divided, bulky, black soot, at one time the most important black pigment used in the manufacture of printing inks. It is produced by the imperfect combustion of pitch resin or tung oil, or fatty substances, such as naphthalene, in a vessel within a tent made of paper or sheepskin. The smoke is deposited on the inside of the tent which is then beaten to cause the soot to fall off. The soot is then heated several times to a very high temperature in a metal container having a small opening in the top, through which the impurities escape. * Chemical Properties Available: Various * Physical Properties Available: 59 to 62 nanometers (Arithmetic mean particle diameter) * Physical Constants: Molecular Weight (g/mol.)
