    Completed paint consolidation and removal of overpaint/varnish on bottom half of painting. A thin coat of non-yellowing, stable synthetic varnish was applied across the bottom section. Began cleaning/consolidation of upper section.

    Completed removal of overpaint and varnish from the bottom half of the painting. The central portion of the canvas appeared to be in excellent condition save for a few old tears while most of the damage appeared to be localized along the outermost edges of the painting. This may have been caused to prolonged exposure to moisture or even how the painting may have originally been displayed (e.g. in a large hall flanked by windows) (Pictured here: Maggie Bearden).

    The residues were successfully reduced using an aqueous emulsion (containing both water and solvent) revealing the original peachy tones of the woman's flesh.

    This sample was collected from the green-colored cushion on King Saul's throne before removal of the degraded surface coating. The red-brown ground contains iron oxides, calcium, and alumino-silicates (Fe, Ca, Al, Si, O, Mg, Mn); the upper ground layer contains more iron and manganese than the lower layer, indicating a higher concentration of earth colors/umbers in the second ground application. The presence of green earth particles was confirmed by the detection of high levels of silica (Si) and moderate to low levels of iron (Fe).<br/><br/><i>Top Left: Ultraviolet light/200x magnification; Top Right: BSE image/217x magnification; Bottom left and right: EDS elemental maps (Major Elements: Si, O, Ca, Al, Fe; Trace: K, S, Mg, Mn)</i>

    This sample was collected from Abner's yellow ptergues (leather straps worn at the waist by Roman soldiers). The red-brown ground contains iron oxides, calcium, and alumino-silicates (Fe, Ca, Al, Si, O, Mg, Mn); the upper ground layer contains more iron and manganese than the lower layer, indicating a higher concentration of earth colors/umbers in the second ground application. The upper paint layers contain lead white (Pb) and yellow iron oxides (Fe, O).

    This sample was collected from the green-colored mountains in the distant background after removal of the overpaint and degraded surface coating. The red-brown ground contains iron oxides, calcium, and alumino-silicates (Fe, Ca, Al, Si, O, Mg, Mn). The paint layer contains lead white (Pb), earth colors (Fe, Si, O), and lead-antimonate (Pb, Sb). The presence of green earth particles was confirmed by the detection of high levels of silica (Si) and moderate to low levels of iron (Fe). A few yellow particles were found to contain lead and antimony (Pb, Sb) pointing towards the presence of Naples Yellow, however a large whitish agglomerate appeared to contain lead, antimony, and high levels of silica (Si). It may be that a range of lead-antimonate particles were used, with some possessing more of a "glassier" nature than others. Colored glass has been found in Italian Renaissance and Baroque paintings.<br/><br/><i>Top Left: Visible light/200x magnification; Top Right: BSE image/2124x magnification; Bottom left and right: EDS elemental maps (Major Elements: Si, O, Pb, Al, Ca, Fe; Trace: K, Mg, Sb)</i>
