The painting Composition (1952) by Jean Paul Riopelle (1923–2002) is part of the Henie Onstad Art Centre’s collection in Norway. Examination of the painting revealed the presence of drips of soft medium exuding from the surface. The main aim of this paper is to report chemical characteristics of its hard, soft and dripping paints. Information was collected about Riopelle’s use of materials. Data were obtained from microsamples by analysis with Scanning Electron Microscopy with Energy Dispersive X-Ray (SEM-EDX) and Direct Temperature resolved Mass Spectrometry (DTMS). Composition (1952) is painted with 26 different colours or shades of paint. All these paints vary in their specific physical condition when tested on the painting. Paints were classified into three categories: hard, soft, softer and dripping. The most problematic of all paints contained cobalt blue pigment. Dripping exudates show relative high DTMS features for polar compounds such as azelaic acid and midchain-oxygen-functionalised stearic acids. Lower relative amounts are present in softening paints. Hard paints are characterised by higher relative amounts of saturated fatty acids ranging from palmitic (C16) to lignoceric (C24) fatty acid. We infer that a physical separation mechanism is responsible for formation of polar micelles that form from oxidising semidrying oils in the paints used by Riopelle. Results from Composition (1952) are compared with another painting by Riopelle from 1956 and one by Pierre Soulages from 1954.
