Fig. 20

²⁰⁶Pb/²⁰⁴Pb vs. ²⁰⁷Pb/²⁰⁴Pb ratios diagram. The figure reports data for 16th Century Italian and 17th Century Dutch lead white as blue and orange fields [13, 14]. The green [DG1] [IPd2] field shows the values of Iranian lead in ceramic glazes identified in the study from Wolf et al. [17]. The diamonds are values for Iranian galena from the Alborz (AZ) and the Central Iran Zone (CIZ) present in Hassan Mirnejad et al. [18]. The samples from the illustration are the yellow circles. The analytical uncertainty, as the 2SD usually reported as a cross, is smaller than the marker and therefore is not visible in the graph
