Two important aspects of the feasibility of using EDXRF for theattribution of porcelains were solved. First, elements such as Mn andCo were defined, and identified as elments characteristic of thecolorant, so ratios between their concentrations (e.g.Mn/Co) are meaningful parameters. Second, it was found thatelements characteristic of the colorant diffuse from the colorantinto the glaze layer during high‐temperature firing.Therefore, the glaze layer also contains information on the colorantwhich can be revealed by EDXRF. It was also shown that thehalf‐value thicknesses calculated for Rb, Sr, Y and Zr comingfrom the body of the porcelain can contribute to the EDXRF results.Therefore, the EDXRF results contain information from the glaze,colorant and the body. This confirms the feasibility of theattribution of porcelains using EDXRF, which is based on thevariation of the materials used for the glaze, colorant and body indifferent periods and localities.
