“…The MA-XRF technique may be provided by portable instruments or by large-scale facilities like synchrotrons [10][11][12]. Despite their higher performances in terms of output beam parameters (higher intensity, smaller spot size), synchrotron facilities have the limitation of needing the artifacts to be transported to the laboratory, which is not always feasible.…”

At present, the use of non-destructive, non-invasive X-ray-based techniques is well established in heritage science for the analysis and conservation of works of art. X-ray fluorescence (XRF) plays a fundamental role since it provides information on the elemental composition, contributing to the identification of the materials present on the superficial layers of an artwork. Whenever XRF is combined with the capability of scanning an area to provide the elemental distribution on a surface, the technique is referred to as macro X-ray fluorescence (MA-XRF). The heritage science field, in which the technique is extensively applied, presents a large variety of case studies. Typical examples are paintings, ceramics, metallic objects and manuscripts. This work presents an uncommon application of MA-XRF analysis to furniture. Measurements have been carried out with the MA-XRF scanner of the INFN-CHNet collaboration at the Centro di Conservazione e Restauro “La Venaria Reale”, a leading conservation centre in the field. In particular, a chinoiserie lacquered cabinet of the 18th century and a desk by Pietro Piffetti (1701–1777) have been analysed with a focus on the characterisation of decorative layers and different materials (e.g., gilding in the former and ivory in the latter). The measurements have been carried out using a telemeter for non-planar surfaces, and with collimators of 0.8 mm and 0.4 mm diameter, depending on the spatial resolution needed. The combination of the small measuring head with the use of the telemeter and of a small collimator has guaranteed the ability to scan difficult-to-reach areas with high spatial resolution in a reasonable time (20 × 10 mm2 with 0.2 mm step in less than 20 min).

“…A specific illustration is the emergence of photonic approaches dedicated to ancient materials at synchrotrons. Since the seminal articles of Brissaud et al and Harbottle et al, synchrotron-based methods have led to a wealth of new information on ancient materials. ,− Ancient materials studies took particular benefit of the extreme brightness, tunability, and transverse coherence of synchrotron sources . These developments included the following in particular: (a) New generations of rapid X-ray fluorescence (XRF) scanners were used to produce elemental distribution maps of artworks combining information on local pigment identities and pictorial composition. , Similar approaches were used to image the composition of hard and soft tissues in flat fossil specimens from natural history collections and to study the chemistry of their fossilization. − (b) X-ray absorption spectroscopy (XAS) has been used to study many heritage materials, in particular paints, glasses, and ceramics .…”

Significance For millennia, Aboriginal Australian peoples have used the extraordinary physicochemical properties of plant exudates from practical applications to cultural expression. We employ state-of-the-art spectroscopy to characterize the molecular compositions of well-preserved, native Australian plant exudates ( Xanthorrhoea , Callitris , Eucalyptus , and Acacia ) from a historic collection assembled over a century ago. This work demonstrates the benefits of X-ray Raman spectroscopy for the analysis of these complex natural systems. It provides key information for a broader understanding of their terpenoid, aromatic, phenolic, and polysaccharide composition and subsequent chemical classification. It complements Fourier-transform infrared and pyrolysis–gas chromatography–mass spectrometry by allowing bulk-sensitive analysis in a fully noninvasive manner and probes molecular features which remain silent in these commonly employed analyses.
