Lampblack

Description

lampblack (at 100x visible light left; UV light right)

A type of carbon black obtained from the soot of burned Fat, Oil, Tar, or resin. Lampblack is soft bluish-black pigment that is very stable and unaffected by light, acids, and alkalis. It was often mixed with Lead white to produce a gray pigment. Lampblack may contain a small percentage of residual fats, oils, or resins. This makes it mix poorly with Water and also makes Linseed oil dry slowly into a soft film. Umber was often added to the mixture as a drier. For use as a watercolor, lampblack was mixed with Glue, prepared in sticks and sold as India ink. Lampblack was one of the major black pigment in early American house paints (Newman and Farrell 1994). Currently lampblack is used as a black pigment in cements, ceramics, inks, Linoleum, crayons, shoe polishes, and Carbon paper.

See also Bone black, Charcoal black, Ivory black and Vine black.
