Century Dictionary and Cyclopedia
    • n lampblack A fine black pigment consisting of particles of carbon, pure or almost pure, used for making paints and ink. It reflects only about two per cent of the incident light. It was formerly made by burning crude oils with the least supply of air possible for combustion, in order to produce a smoky flame, the soot being collected in a receptacle called a lampblack-furnace, and was prepared for use by being heated to redness in iron boxes. It is now generally made by allowing gas-flames to impinge on cylinders of iron chilled by a stream of cold water flowing through them, The lampblack collects on the cold surfaces, and is removed and collected by machinery. This form of lampblack is known as carbonblack or gas-black.
    • lampblack To treat with lampblack; coat with lampblack.
