  • Evaluation of lead isotope analysis as a means of locating the origin of medieval brass artefacts : Application of the method to the baptismal fonts of Saint Germain at Tirlemont and of Saint Barthélemy at Liège


The aim of this research was to locate the origin of the metal used to make the baptismal fonts of Saint Barthélemy, Liège, using as reference the baptismal fonts of Saint Germain, Tirlemont, the origin of which is well-established. Mass spectrometry analysis was used to measure amounts of the different lead isotopes present in both sets of fonts. Comparison was made with reference data and with existing data on radiogenic isotopes in galena from several sources and in objects from archaeological sites.
