“…This paves the way to internal page-by-page virtual reading of ancient manuscripts. Pioneering tests [13], [14], [15], [16], [17], [18], [19] about the use of tomography for cultural heritage research provided a good background for our approach.…”

We present x-ray imaging results for diverse ironbased-ink antique writings -single-page manuscripts, stacks and scrolls -from the 16 th century on. The objective is to elaborate new digitization techniques by x-ray tomography for the "Venice Time Machine" (VTM) project in collaboration with the "Archivio di Stato". The technique can potentially read unopened -perhaps unopenable -documents and speed up the entire digitization process of large collections. The technique is feasible thanks to the highly absorbing chemical elements in ancient European ink recipes. The corresponding x-ray contrast allows character reading with reasonably short exposure times. The impact is quite relevant: the potential feasibility of "softer" and faster digitization of huge collections like the Archivio di Stato -80 km of documents spanning 10 centuries.

“…Both chemical approaches and XCT are both, individually, common tools for analysing the conservation of many objects in cultural heritage. XCT has been used in many different contexts, including assessing the condition of sensitive objects such as scrolls [28, 54, 61, 62], furniture [17], instruments [15, 63], building materials [24, 25], sculpture [27], statuary in stone, wood and bronze [64–67], paintings [26], identifying artefacts embedded in soil blocks extracted from archaeological sites [68], identifying the contents of unlabelled plaster casts [69], identifying structures obscured by corrosion crusts [70, 71] and weaponry [72] among a substantial variety of other conservational applications within the field of cultural heritage. XRF and EDX, although XRF more so, are commonly used techniques within the field of cultural heritage and have been utilised in many applications, dominantly in assessing the condition of paintings and the materials they are made from [73, 74].…”

X-ray computed tomography (XCT) and chemical analysis (EDX and XRF) used in conjunction for cultural conservation: the case of the earliest scientifically described dinosaur Megalosaurus bucklandii

et al. 2018

This paper demonstrates the combined use of X-ray computed tomography (XCT), energy dispersive X-ray spectroscopy (EDX) and X-ray fluorescence (XRF) to evaluate the conservational history of the dentary (lower jaw) of Megalosaurus bucklandii Mantell, 1827, the first scientifically described dinosaur. Previous analysis using XCT revealed that the specimen had undergone at least two phases of repair using two different kinds of plaster, although their composition remained undetermined. Additional chemical analysis using EDX and XRF has allowed the determination of the composition of these unidentified plasters, revealing that they are of similar composition, composed dominantly of ‘plaster of Paris’ mixed with quartz sand and calcite, potentially from the matrix material of the Stonesfield Slate, with the trace presence of chlorine. One of the plasters unusually contains the pigment minium (naturally occurring lead tetroxide; Pb 2 2+ Pb 4+ O 4 ) whilst the other seems to have an additional coating of barium hydroxide (Ba(OH) 2 ), indicating that these likely represent two separate stages of repair. The potential of this combined approach for evaluating problematic museum objects for conservation is further discussed as is its usage in cultural heritage today.

Depending on the energy and intensity of the neutrons used, and composition of the samples studied, the artefact may remain radioactive for periods of time between hours and years (Bettuzzi et al 2015).…”

Recycled Blessings: An Investigative Case Study of a Rewrapped Egyptian Votive Mummy Using Novel and Established 3D Imaging Techniques

This case study was the first of its kind, where neutron computed tomography (CT) was applied to a wrapped mummified animal. Conventional X‐ray CT was also used to allow for meaningful comparison, and complementary data for a comprehensive investigation. Previous applications of both techniques are limited to metallic objects, such as bronze Buddhas. The mummy used in this study (IA.2402) is dated between the Third Intermediate Period (1069–664 bce) to Late Period (664–332 bce) according to the wrapping style, and was originally believed to contain a complete skeleton of a feline. However, precise date and provenance were unknown. Our results prove the presence of only partial juvenile feline remains, and provide a date range for artefact creation (900–804 bce ± 30) and alteration (367–204 bce ± 30). Therefore, this study implements an established imaging technique (neutron CT) in a novel way, while preserving and conserving the intrinsic value of the artefact through non‐destructive investigation.
