Cross-section seen under a scanning electron microscope [SEM] of a microsample taken from of the right wing of the dove (G: ground, P: primer, PT: paint layer). Right, the EDS spectrum obtained after analysing the primer layer (I) in which we detect the elements Fe, Mn, Ca, K, Si, Al and Na from ochre pigments. We also detected the presence of umber (Mn) in this work, which lends the red primer a darker tinge.
