Georges Seurat first employed his divisionist painting technique on A Sunday on La Grande Jatte – 1884 beginning in October 1885. Painting with pigments representing colors seen in the visible spectrum that were minimally mixed on the palette and using divided brushstrokes, he aimed to impart luminosity to the surface and to explore 19 th century ideas of(More)
The purpose of this article is to discuss the process of colorizing a historical arti fact-a black and white archival photo of Bathers by a River, 1909-1917, by Henri Matisse (Art Institute of Chicago 1953.158), taken in November 1913, when the art ist was still working on the painting and showing it in a significantly differ ent state compared to the one(More)
Organic dyes extracted from plants, insects, and shellfish have been used for millennia in dyeing textiles and manufacturing colorants for painting. The economic push for dyes with high tinting strength, directly related to high extinction coefficients in the visible range, historically led to the selection of substances that could be used at low(More)
This paper describes the use of a customized algorithm for the colorization of historical black and white photographs documenting earlier states of paintings. This study specifically focuses on Pablo Picasso's mid-century Mediterranean masterpiece La Joie de Vivre, 1946 (Musée Picasso, Antibes, France). The custom-designed algorithm allows(More)
X-Ray fluorescence (XRF) scanning of works of art is becoming an increasingly popular non-destructive analytical method. The high quality XRF spectra is necessary to obtain significant information on both major and minor elements used for characterization and provenance analysis. However, there is a trade-off between the spatial resolution of an XRF scan(More)
Surface-enhanced Raman spectroscopy (SERS) is an ideal tool for analyzing dyes on historical textiles because it requires very little sample compared to other available analytical methods and analysis can be done directly on the fiber. This paper reports on the first systematic study of the use of citrate-reduced silver colloidal pastes for the direct,(More)

The views expressed in this paper are those of the authors and should not be taken to represent those of the organisations of affiliations. A pressing and(More)
Inductively coupled plasma-optical emission spectroscopy (ICP-OES) was used to determine the bulk metal elemental composition of 62 modern bronze sculptures cast in Paris in the first half of the twentieth century from the collections of The Art Institute of Chicago and the Philadelphia Museum of Art. As a result, a comprehensive survey of the alloy(More)
