(Wiley) Rembrandt van Rijn's paintings are renowned for their masterful representations of light and shadow and a characteristic plasticity generated by a technique called impasto. Now, scientists have analyzed impasto layers in some of Rembrandt's paintings, and the study, which is published in the journal Angewandte Chemie, reveals that the impasto unexpectedly contains a very rare lead mineral called plumbonacrite. This finding suggests that Rembrandt used a unique paint recipe.
