Short summary
Could the gesture of an ancient artist applying a paint layer be reconstructed using EPR analysis? In the case of an inorganic pigment widely used in antiquity, Egyptian blue, where the anisotropy of the Cu2+ EPR signal reflects the symmetry of the pigment crystallites, we have shown that the orientation distribution of the grains, as revealed by simulation of EPR spectra, is indeed influenced by the nature of the gesture.
