Scientists from the Rijksmuseum, CNRS, the European Synchrotron Radiation Facility, the University of Amsterdam, and the University of Antwerp made a rare discovery of lead formate in Rembrandt's The Night Watch. This first-ever discovery in painting research offers a new understanding of 17th-centu
The Night Watch
The team of scientists combined multi-scale imaging methods in order to chemically study the materials used by Rembrandt in. An X-ray scanning instrument developed at the University of Antwerp was applied directly to the painting, while tiny fragments taken from the painting were studied with synchrotron micro X-ray probes, at the ESRF, the European Synchrotron , and PETRA-III facility . These two types of analyses revealed the presence of an unexpected organo-metallic compound: lead formates.

To answer these questions, the scientists studied fragments taken fromThey worked with the hypothesis that Rembrandt used an organic medium containing dissolved lead oxide to enhance its siccative properties.
