Isotopic ratios of lead extracted from ancient objects may reveal geo graphical origin and hence possibly provenance. Lead ore samples are in the process of being analyzed. To illustrate the versatility of lead isotope studies 5 groups of objects are reported on: (1) 3 early classical bronzes, ranging from 3rd century B.C. To 2nd century A.D.; (2) White lead in paintings; (3) Lead camings in medieval stained glass windows; (4) Ancient red, yellow and green opaque glass which can contain 3 30% lead oxide; and (5) Lead in silver coins and gold and other objects.
