Comparison of rapid preparation methods for Pb isotope analysis of high‐Pb ceramic glazes: A case study of late medieval Besztercebánya/Banská Bystrica‐type stove tiles

Abstract This study identified the provenance of Pb flux used in production glaze unique, high‐quality late medieval stove tiles from northern part Carpathian Basin, and elaborated evaluated a fast preparation process to measure isotope ratios high‐Pb glazes. We compared three different methods preparation. Method 1 consisted dissolution bulk chips glaze, dilution solution mass spectrometric analysis without purification. 2 collected surface with acid‐impregnated swabs, subsequent direct sample solution. 3 solutions method 1, extraction by ion‐exchange chromatography purified Pb. Each produced similar ratio. The majority fall into one group indicate that lead imported Krakow–Silesia mining region was mainly for glazes made workshops.
