A hard, yellow, translucent resin, found as a fossil in beds of lignite, in alluvial soils, and on sea-coasts, especially the Prussian coast of the Baltic. It takes a fine polish, and is much used for making ornaments, such as necklaces, earrings, pendants, and beads; for the mouth-pieces of pipes and cigar-holders, and for burning for perfume. It is also used as a basis for a fine varnish. By friction it becomes strongly electric.
