LAMP-BLACK, the soot produced by burning resin, turpentine, pitch, oil, and other matters, in such a manner that large bf smoke are formed and collected in properly arranged receptacles. Lamp-black is the coloring matter of black and slate colored paints.
Large quantities of this pigment are made in Germany by burning the refuie resin and fragments of fir and pine trees. The combustion is carried on slowly, and tile dense smoke passes up a long flue, at thelop of which is a large hood made of coarse cloth. In this hood the carbon is deposited rapidly at the rate of 20 to 30 pounds an hour, which is collected by lowering the cloth hood, and shaking it out. In Great Britain a similar process is adopted; but large quantities of an inferior kind are also collected from the flues of coke-ovens; and a superior kind, known as bone-black, isa obtained from the flues of kilns in which bones are calcined for manure. By mixing
lamp-black in various proportions with white-lead, every gradation of color, from jet black up to slate and gray, can be easily produced.
(anc. Pelagia), a small uninhabited island in the Mediterranean sea. about midway between Malta and the coast of Tunis. It belongs to the kingdom of •Italy, having been formerly a dependency of Sicily. It is about 7 in. in length, and in most places not quite one m. in breadth, its circuit being about 13 miles. The w. part of the island is covered with dwarf olives;' and these and other shrubs supply great quantities of firewood, both to Tripoli and Malta. Great numbers of wild goats inhabit the island. Lampedusa was at one time inhabited. Near it are the two islets of Lampione and Linosa.
