Abstract

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.
