The Celtic oppidum Staré Hradisko north of Brno in Moravia, CSSR, has long been noted for its wealth of archaeological amber artifacts. Since there are several substantial deposits of fossil resins in the immediate vicinity of the site, it has been an open question whether the settlement was a centre of exploitation and exportation of these local raw materials, or whether it was an entrepôt of Baltic amber on its way to southern and southeastern Europe. Because of extensive weathering, many of the amber finds at Staré Hradisko cannot be identified by infra-red spectroscopy. A new analytical method, which determines the amount of succinic acid by means of gas chromatography, has been developed to show that the amber of Staré Hradisko is, in fact, of the Baltic variety called succinite.
