"Lautrec was greatly influenced by the techniques, style and subject matter of Degas, who was a close neighbor between 1887 and 1891. ...Like Degas, Lautrec experimented with painting with which was called peinture à l'essence. In Degas' method, oil was drawn out of his colours by placing them on blotting paper. Then the chalky paint was diluted with turpentine and applied like a wash to his support. Because the turpentine spirit evaporated quickly, the colours dried rapidly, so that the paint surface could be reworked and built up without enormous delays. Unlike paint applied thinly in glazes, with this technique the colour dries mat, and has a chalky surface only thinly and sparely coloured."
