“It is interesting that plumbonacrite was found in the impasto layer only,” says Rebecca Ploeger, an expert in art conservation science at Buffalo State who was not involved in the research. Litharge oil dries faster than many other binders, she says, and can therefore be used to quickly form impasto layers. Next, Gonzalez and coworkers would like to expand their impasto studies to include more of Rembrandt’s work as well as paintings by his contemporaries to see if the plumbonacrite is specific to Rembrandt’s paintings. The work “is an exciting next step into learning more about how Rembrandt, and possibly other artists, worked with and deliberately selected materials to achieve specific effects, such as impasto,” says Fiona T.
