- Résumé
- This research project was initiated after a private art collector believed that two paintings that he and his wife owned looked to be by the hand of the same artist. Both were oil paintings on panel circa 1920 which appeared to be plein air oil sketches depicting scenes from the French coast. Both showed heavy impasto and were painted with a similar gestural manner while showing some similarities in the color palette. One painting was an autographed painting by the Scottish/Canadian artist Berthe Des Clayes; the other was an unsigned painting with the possibility of the same authorship. Using scientific analysis, this technical examination compared the two paintings to determine how similar the methods and materials were. The technical methods of analysis included normal light examination and photography including raking light, ultraviolet radiation, infrared reflectography, and x-radiography. X-ray fluorescence analysis (XRF) was used to analyze the ground and pigment layers. Scientific analysis involved micro samples taken to produce material for infrared spectroscopy (FTIR) and for cross-section analysis with polarized light microscopy (PLM). Further, environmental scanning electron microscopy-energy dispersive x-ray spectroscopy (ESEM-EDS) was employed to better determine the elemental composition of the ground and pigment layers found in the sampled cross sections. The methods of analysis produced many similarities between the paintings, including very similar paint application and layering structure. Other similarities included many common pigments and their use in similar paint layers. FTIR produced strikingly similar spectra from samples taken from each painting. The technical data suggested a consistency between the two works, possibly indicating that the unsigned painting could be by Berthe Des Clayes.
