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

Investigating counterfeiting of an artwork by XRF, SEM-EDS, FTIR and synchrotron radiation induced MA-XRF at LNLS-BRAZIL.

Spectrochimica Acta Part A - Molecular and Biomolecular Spectroscopy, 2020
In this work, a painting suspected of counterfeiting was analyzed using the synchrotron-based scanning macro X-ray fluorescence (MA-XRF) technique. The canvas has erasures including a signature erasure; however, some visible numbers indicate that the ...

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. As a
