The history of painting, as the art critic James Elkins suggests in his book "What Painting Is," is in part a history of the changing chemical composition of paint.
The chemical composition of paints has been examined, and some paints have even been radioactively dated (it is the lead content that is key here).
A similar composition of painting layers, with high gypsum content, has been also found in some areas of S. Fermo Maggiore Church in Verona.
A link between the composition of paint and a source material (e.g. a local ochre mine) has the potential provide valuable archaeological information.
However, a growing body of reference data on the composition of paints from this period may help to provide more informed interpretations and distinctions between the different types of paints.
A complete picture of the composition of paint components also means optimizing conservation strategies, which are fundamental when dealing with dyes and organic pigments, which are probably the most fugitive materials present in a work of art.
Thus, while previous studies have shown the inorganic composition of paint swatches in Ripolin brochures to be highly consistent with the commercial paint in the cans [19, 35], the organic composition of the swatches must be interpreted with caution and may not give an accurate reflection of the actual formulation of the commercial products.
The first time the author of this work carried out a study to determine the composition of binders in Roman murals, the extraction method used was developed in the same laboratory in which the study was performed1, and it was successfully used to analyse the composition of paints dating from recent centuries, as had been commonly studied in that laboratory [35].
One of these, which Mr. Jungles owns — an 8-by-17-foot composition of 1,325 painted ceramic tiles — is suspended above the reflecting pool under the palm house's dome, surrounded by thousands of red, orange and yellow orchids.
Multispectral imaging was used for the collection of surface spectral data, which were subsequently processed by means of cluster analysis in a novel approach to map the composition of the painted surface.
The component spectral enhancement constraint maximizes the difference between the pixel contributions and thus provides a better separation of the paint layers and a more direct information of the composition of the paints instead of paint ingredients.
