Originals vs. Forgeries: The Significance of White Pigments in Artwork Evaluation

Popis výsledku v původním jazyce

The study presents results obtained during an extensive project dealing with the identification of forgeries of famous Czech painters from the first half of the 20th century – Josef Čapek, Emil Filla, Josef Šíma, Václav Špála and Jan Zrzavý. In art authentication, it is essential to gather enough relevant information from scientific examination of original paintings, because this helps us determine art materials used by a particular artist in a given period. The research focused on white pigments, as they are good markers of the paintings’ date of origin, especially in the period between the 1920s and the 1950s. To identify the materials, we employed non-invasive molecular analysis (Raman spectroscopy) combined with elemental analysis (X-ray fluorescence spectroscopy). Using titanium white as an example, we explored the availability and import of this pigment in Czechoslovakia. Czech painters used titanium white with anatase structure rather sparingly, even though it was available on the market at the latest in 1928 and was still used in the 1950s. Rutile has been identified in two artworks from the second half of the 1960s. In addition to traditional white pigments, lead sulphate was also present in the studied artworks. This white pigment has been detected in only a few paintings, suggesting it was not very common. In the Czech milieu, lead sulphate was found exclusively in the paintings from the 1920s and the 1930s. The results obtained through this investigation provide valuable information about the use of different pigments by individual painters. They can serve as comparative data in the process of art authentication.
