Zusammenfassung:•Heterogeneity of lead isotopes of lead white within painting assessed via micro-invasive analyses and MC-ICPMS.•Lead isotopes of lead white within a painting for provenance and authentication.•Lead isotopes of lead white identify later modification of paintings.•Time dependent trend found in lead isotopes of lead white for 17th century paintings. The heterogeneity of lead isotope ratios of lead white paints within individual paintings is evaluated. The analyses of five different 17th-century Dutch paintings, sampled in different locations, identifies the presence of isotopic heterogeneity in lead white within a single painting. Pure pigment in the form of cones of 16th-century Venetian lead white, in contrast, was found to be isotopically homogeneous. The study evaluates the origins of the increased heterogeneity of lead isotope ratios in the evolution from the pure pigment to the artwork.
