The artist used lampblack to create deep, rich shadows in her painting.
Lampblack is formed from "lamp" (from Old English "lamp", meaning a device for producing light) and "black" (from Old English "blæc", meaning the color black). The word "lampblack" refers to a black pigment made from soot produced by burning oil or fat in a lamp.
Think of a 'lamp' that produces light and the 'black' soot it creates — that's how lampblack is a black pigment from lamps.
