Summary of analytical report (statment): Painting on canvas, portrait of a woman
On November 21th 2012, CARAA was mandated to analyze by X-ray fluorescence (XRF) three areas of a painting on canvas depicting the portrait of a woman.

    The analyzed areas concerned three colors:
  • The white, identified as lead white with traces of lithopone.
  • The red, consisting of vermilion.
  • The brown, mainly consisting of red ocher.

All pigments analyzed in this work are contemporary with the second half of the nineteenth century.

The results of these analyzes are currently part of the elements taken into account for a possible allocation to the work of Gustave Courbet.

New research program “GALLE”: Non-invasive study of the work of the glass maker Emile Gallé

CARAA, in collaboration with the LARCROA and the Museum of the Ecole de Nancy started a new research program to better understand and to reference the material used by one of the most distinguished glass masters of Art Nouveau, Emile Gallé (1846-1904).

Together with the Museum of the Ecole de Nancy, some forty works from the museum’s collections were selected based on their historical, technical, aesthetic or chronological interest. These works cover a production period from 1886 (the first works of the artist) until 1916 (produced by the workshop of E. Gallé after the death of the artist in 1904). The data, acquired in-situ by non-invasive X-ray fluorescence spectroscopy, are being studied and will be used after correlation with the historical data and recipes, to identify the materials as well as to better understand the techniques used by E. Gallé.

The characterization of the artist’s palette will also help to differentiate the authentic pieces of Gallé from counterfeit.
