Ore samples and artifacts from Albania were analyzed in the Keck Lab using an acid digestion process by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Samples were prepared for analysis using microwave digestion. The microwave procedure digests the samples at elevated temperatures under pressure with hydrofluoric and nitric acid, followed by boric acid. This digestion procedure is designed to dissolve the soil and sample components, and releases the metals for analysis by ICP-MS. The objective of the analysis of the artifacts by ICP-MS was to establish the provenance of the artifacts found in Albania. Samples were collected from various regions in the country including Shkodra, Durres, and the Shala Valley. Since different geological regions will often exhibit a particular mineral signature, it is possible to identify the origins of the artifacts by matching their mineral content to their geographic region, and ultimately use this information to identify potential trade routes.
