time for his Girl Asleep at a Table (62) and The Officer and the Laughing Girl (approximately 44), but somewhat below The Milkmaid (177). Painting materials The first pigment analysis of this painting by Hermann Kühn revealed the use of ultramarine for the blue tablecloth and lead white for the grey wall. The pigment in the bright yellow curtain was identified as Indian yellow. The subsequent technical investigations of the painting by Robert L. Feller (1974) and M.E. Gifford (1994) have shown that the painting had been extended by approximately five centimetres on every side at a much later date. The sample investigated by H. Kühn in 1968 was unfortunately taken from this extension. The proper pigment of the yellow curtain is lead-tin-yellow. The full pigment analysis according to the latest data is illustrated at Colourlex.
