The following elements were detected using XRF-analysis and on the basis of their optical properties the following pigments were identified:
Yellow (veil): Ca, Pb, Fe, Sr (Sn)
Ca: chalk/ gypsum(?); Pb: lead white; Pb/ Sn: lead-tin-yellow (?); Fe: iron oxide/ ochre (?); Sr: component of chalk (?)
Blue (eye): Pb, Ca, Hg, Fe, Sr (Cu)
Pb: lead white; Ca: chalk/ gypsum (?); Hg: vermillion; Fe: iron oxide/ ochre (?); Cu: blue pigment containing copper; Sr: component of chalk (?)
White (pearl): Pb, Ca (Fe, Sr)
Pb: lead white; Ca: chalk/ gypsum (?)
Green (gem stone) Pb, Cu, Ca, Fe, Sn, Hg, Sr
Pb: lead white; Cu: green pigment containing copper; Ca: chalk/ gypsum (?); Pb/ Sn: lead tin yellow (?); Hg: vermilion; Fe: iron oxide/ ochre (?); Sr: component of chalk (?)
Yellow (necklace): Pb, Fe, Ca, Sn, Hg, Sr, (As)
Pb: lead white; Pb/ Sn: lead-tin-yellow; Fe: iron oxide/ ochre (?); Ca: chalk/ gypsum (?); Hg: vermilion; Sr: component of chalk (?); As: orpiment(?)
Yellow (veil): Pb, Ca, Sn, Au, Sr, Fe, (As)
Pb: lead white; Pb/ Sn: lead-tin-yellow; Ca: chalk/ gypsum (?); Au: gold; Sr: component of chalk (?); Fe: iron oxide/ ochre (?); As: orpiment(?)
Pigments: lead white, lead-tin-yellow, vermilion, iron oxide/ ochre, azurite, verdigris and possibly orpiment. Gold was detected in the veil.
The paint was applied in several layers with different brushes both flat and stippled. The flesh paint was laid in with a pale mixture of lead white and vermilion pigments as well as brownish-grey half shadows. These were then reinforced with semi-transparent brown glazes and highlights were applied with a lighter and at times pinker flesh paint. The white paint in the eyeballs contains small amounts of azurite. The iris is modelled with grey and brown paint. In the black pupils, the reflection of a window is indicated by four white highlights. In the left eye, these reflections were created with two vertically drawn white lines and then divided into four points with a horizontal line in black paint. The strands of hair are finely executed, using whitish-yellow paint on the flat brown underpaint. A semi-transparent veil is indicated with a thin application of white paint. The edge was initially painted white and then highlights were added in lead-tin-yellow. There is also some gold (gold leaf or shell gold). The collar was laid in with a reddish-brown paint (iron oxide). Red and green stones, pearls and decorative elements were then painted on, and some detail was added with gold. Further differentiation was carried out with lead tin yellow. The white pearl is probably original, as no evidence suggesting the contrary was found. An initial layer of yellow ochre was used to paint the chains and then they were modelled with a brownish-red paint, yellow (lead tin yellow) and black paint was used to create volume. The x-radiograph does not show any evidence of significant compositional changes during the painting process.
