The study used noninvasive and non-destructive analytical methods, and aims to determine what pigments Arosenius used and how well the analytical methods perform in examination of this particular object. The basis for this study is the lack of knowledge about the use of materials by Arosenius. A three-year research project, called the Arosenius Project, is currently gathering information about the artist, aiming to digitize and make it more accessible for researchers and for the public. The project is based in Gothenburg and Stockholm and is funded by The Royal Swedish Academy of Letters, History and Antiquities and Riksbankens Jubileumsfond. The results of this study will contribute information to the project and to the general understanding of Arosenius' artistry. Examination was conducted using optical microscopy, X-ray fluorescence (XRF), ultraviolet-visible fiber optic reflectance spectroscopy (UV-VIS FORS), and multispectral imaging (MSI). The methods provided information about the color, chemical composition, and reflectance spectra of the pigments, as well as their properties in various spectral ranges. A probable identification is presented for 27 of 31 pigment samples in the sketch book. 15 different pigments have been identified, vermillion being the most frequently used. The study shows that the analytical methods are useful for pigment identification, but examination of objects of art is complex due to small areas of analysis, mixed and/or layered pigments, and to the consideration of the safety of the object.

The painting shows signs of degradation in the form of staining, pigment loss, and discolored varnish. The study aims to identify the materials of the painting, and how the materials and condition are affecting the appearance of the painting. It also aims to explore the use of cardboard as a support for oil painting. The overall objective is to contribute to the knowledge gap in the research about Bonnard's use of materials and about conservation issues related to his paintings. A literature review was conducted on Bonnard in an art historical context. The review involved examination of art historical sources, museum records, artist catalogs, and scientific articles. The study used various analytical methods to perform investigations of the painting. The methods include analytical imaging, microscopy, microchemical testing and spectroscopic analysis (X-ray fluorescence spectroscopy and Fourier-transform infrared spectroscopy). The results of the investigation include the identification of four pigments (zinc white, cadmium yellow, vermillion, and cobalt chromite blue) and a dammar varnish. The results also indicate that the varnish was not applied by Bonnard himself. The examination of the cardboard showed that it consists of several different fibers (wood, cotton, bast and grass, or possibly wool, fibers) and that the cardboard is acidic. The acidity is most likely affecting the condition of the painting negatively, as does the presence of oil in the cardboard.
