“…An alizarin-based red was found in the red areas, yielding typical bands at 846, 1190, 1276, 1298, 1351, 1366 and 1472 cm −1 in the DRIFT spectrum ( Fig. 11a) [7,9]. It needs to be emphasised that a clear discrimination between PR83 (synthetic alizarin) and natural madder lake is not possible with this method, but we would rather assume PR83 in the 1910s than its natural analogue.…”

“…It has often been reported in various artworks and 20th-century reverse glass paintings [e.g. 7,9,48]. PB52 is formed by combining an acidic (Alizarin Saphirol B, CI 63010) and a basic dye (Methylene Blue, CI 52015) [49] and was previously identified in a product palette for artists' colours made by Farbenfabriken vorm.…”

“…is a relatively straightforward phenomenon, diffusion is more complex since it depends on the pigment speci cations such as particle size, angle of impact, suspending medium, and difference in refractive index of pigment [12]- [14]. Some spectrophotometers such as FORS methodology provides the possibility to collect re ectance spectra from very small areas of the surface of paintings.…”

“…Spectrophotometry presents spectral information in various archaeological, artistic, medical, biochemical sciences [10], and artworks [1], [11], revealing distinctive features not visible to the naked eye. The re ection spectrum of each pigment is speci c for that individual pigment, the same as ngerprint for human [12].…”
