From: Fading into the background: the dark space surrounding Vermeer’s Girl with a Pearl Earring
Sample 19 from the background in the lower right: a Light microscopy of cross-section, bright field. 1: ground, 2: underlayer, 3: glaze. b Light microscopy of cross-section, UV fluorescence. c SEM backscatter image of cross-section. d SEM–EDX map of cross-section: Pb (blue), Ca (magenta), Si (green), K (teal), Fe (red). e SEM–EDX map of cross-section: copper (Cu). f Light microscopy of a fragment in dispersion, transmitted light. 1: ground, 2: underlayer, 3: glaze, 4: (restoration) varnish and dirt. Image: Guusje Harteveld. g MS-OCT B-scan close to the location of Sample 19, with segmentation indicated for: glaze–underlayer interface (purple) and air–varnish interface (yellow). Lateral scale here is different from other parts of this figure
