Investigating palettes used in the painting of Rembrandt’s Man with the red baret using X-ray fluorescence scanning and t-distributed stochastic neighbour embedding

It is assumed that 17th century paintings were painted by a very systematic approach which involved the use of very specific palettes. For every pictorial unit, such a skin, a very specific palette was created. In this case the palette would then only be used to paint the skin and nothing else. The result is that for each pictorial unit a...

Jackson Pollock’s Number 1A, 1948: a non-invasive study using macro-x-ray fluorescence mapping (MA-XRF) and multivariate curve resolution-alternating least squares (MCR-ALS) analysis

Jackson Pollock’s Number 1A, 1948 painting was investigated using in situ scanning macro-x-ray fluorescence mapping (MA-XRF) to help characterize the artist’s materials and his creative process. A multivariate curve resolution-alternating least squares (MCR-ALS) approach was used to examine the hyperspectral data and obtain distribution maps and...
