MA-XRF and XRD analysis revealing a polychrome Centuripe vase

Journal of Archaeological Science: Reports, 2021
Abstract The testimony of Hellenistic culture in Sicily can be studied, nowadays, thanks to archaeological artifacts such as polychrome Centuripe vases. However, since the number of vases available is restricted to just over a hundred pieces, comparative studies of these vases are not easily performed due to the lack of analytical results’ databases.

MA‐XRF investigation of the Altenberg Retable from 1330

X-Ray Spectrometry, 2018
The Altenberg Retable is one of the most important works of German art from the early 14th century. Composed of a shrine, a Madonna figure, and painted wings, it once adorned the high altar of the convent church in Altenberg/Lahn. The side and rear walls of the shrine were overpainted in 1609.

“Costruzione del viadotto”: MA‐XRF in the pictorial executive technique of Agostino Bosia

X-Ray Spectrometry, 2020
During the restoration process of a huge oil canvas (266 cm × 361 cm × 3 cm) by Agostino Bosia, a deep diagnostic campaign was carried out to characterize the original materials and those stratified over time. The activity was supported by the technologies available today in the field of conservation of the Cultural Heritage. Multispectral analyses (UV

Macro X-ray fluorescence scanning (MA-XRF) as tool in the authentication of paintings

Microchemical Journal, 2018
Abstract Scanning macro X-ray fluorescence (MA-XRF) was evaluated as a means for the non-invasive study of two paintings to investigate their authenticity. The first painting, a still-life attributed to the 17th century Spanish painter Francisco de Zurbaran, was analysed both with point XRF analyses and MA-XRF.

MA-XRF and hyperspectral reflectance imaging for visualizing traces of antique polychromy on the Frieze of the Siphnian Treasury

Microchemical Journal, 2018
Abstract Of the once colourful decoration of antique Greek statues only few traces remain today. But these allow one to reconstruct part of the polychromy, based on visual and microscopic inspection and spot analysis with spectroscopic methods. For the first time we used mobile hyperspectral reflectance imaging in the visible and near infrared range ...

The process of MA-XRF data for spectroscopy imaging in cultural heritage

2021
Scanning macro-X-ray fluorescence analysis (MA-XRF) is rapidly being established as a technique for the investigation of historical paintings. The elemental distribution images acquired by this method allow the visualization of hidden paint layers and thus, provide insight into the artist's creative process and the painting's conservation history.
