Fig. 2

Lead isotope composition of lead white pigments from colonial qeros and lead white paints from European paintings. Note that pigments in Groups 1 and 2 overlap with signatures of lead white paints from 17th-19th century Europe, but that pigments in Group 3 do not. See text for further explanation. Note that Keisch and Callahan [57] and Fabian and Fortunato [64] do not provide isotopic signatures of individual paintings, but instead report the ranges of isotopic ratios measured on groups of paintings. Accordingly, we depict these signatures as regions using only the specific isotopic ratios provided by each study. Symbols are larger than errors. Data on European lead white paints were compiled from refs [53, 54, 63]
