For all artifacts that are to serve as archaeological evidence, the study of the provenance, production technology, and trade of raw materials must be based on archaeometry. Currently, these questions are addressed by the use of radiogenic isotope analysis. The book captures the state of the art in this rapidly advancing field. It includes methodological papers on isotope analysis, innovative applications of several isotope systems to current questions in glass and glaze research, and advances in the knowledge of the economy of vitreous materials.
