Carbon analysis in glass is a very difficult task. In the production of glass with Roman wood-fired glass furnaces, one can expect carbon contamination from absorption of fuel gases and/or powdery residues from furnace walls in the glass melt, and also residues from plant-ash used as flux. Sometimes carbon was intentionally added to get a distinct colour to glass. We have developed a highly sensitive non-destructive nuclear technique for carbon analysis by deuteron activation based on C-12(d,n)N-13 reaction. The method is simple, rapid and can help archaeologists understand more about the...

This paper reports the results of experimentation about the removal of a polymeric film of aged Paraloid B72R placed to protect some wooden artifacts belonging to the Egyptian collection of the National Archaeological Museum of Naples (MANN), in particular the study was conducted on two shabties dated to the 19th Dynasty and a sculpture of Ptah-Sokar-Osiris dating to the late period. Thanks to the collaboration between the National Archaeological Museum of Naples and the Laboratory of Restoration of Wooden Artifacts of the University of Naples Suor Orsola Benincasa, it was possible to...

In the frame of an experimental study focused on structural reinforcement of wood by consolidation, developed during two master's theses in Conservation and Restoration of Cultural Heritage (Turin Universiy in collaboration with Centro Conservazione e Restauro La Venaria Reale), the potentials and limits of possible investigation techniques to verify the performances of the treatments, both superficially (optical and electron microscopy) and in terms of penetration (microtomography) were evaluated. This paper discusses the main preliminary results, with particular attention to the micro-CT...

In the context of the conservation of cultural heritage, a problem to be solved is the biological degradation of monuments. The biocidal agents used for cleaning biodegraded surfaces are few and must have adequate requirements. One of the main challenges is the development of eco-friendly products for the conservation and restoration of cultural heritage. Deep Eutectic Solvents (DESs) are a class of green solvents, beneficial and safe that could be used as biocides in cleaning and preserving cultural heritage. In this contribution, five different DES were applied for the first time as...

In the basilica of St. Salvatore, antependiums belonging to different phases of monument decoration are visible. The most valuable, the marble frontal of the high altar, dates to 1511 and is probably the only one from the first decorative phase of the church. The side altar frontals appear to be made of wood, embroidered damask, or other fabrics. They are partly related to the renovations the basilica underwent when it was reopened for worship in the early 20th century, except for this frontal in St. Mauro’s Chapel, which was plausibly made during the early 18th-century redecoration of the...

The Vincenzo Ragusa and O’Tama Kiyohara artefact collection belonging to the Liceo Artistico Ragusa Kiyohara in Palermo is one outstanding example of the artistic encounter between the European and Eastern worlds. In this contribution, we report a physical-chemical characterization of Japanese fabrics of the Ragusa- Kiyohara collection. Metallic threads finely decorate these fabrics conferring their preciousness. The X-ray fluorescence (XRF) analysis and the Attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy were used as complementary techniques for elemental...

This paper describes the results of preliminary application tests for a stand-alone prototype data acquisition system. The system was developed for monitoring and characterizing the vibroacoustic landscape and, in particular, the vibroacoustic heritage, such as music instruments or performing spaces. The tests, performed on a building in the historical center of Napoli, show a possible interconnection between acoustic and displacement signals, as external forcing of the monitored structure, with exchange of the cause-and-effect roles, especially at low frequency.

The application of non-destructive techniques in the field of cultural heritage is becoming fundamental to understanding degradation phenomena. In this study, Transient Absorption (TA) spectroscopy and colorimetry were exploited to explain the process which causes the degradation of some pigments, like Red Vermilion and cadmium yellow. The optical properties involved in the process are studied before and after exposing the pigments to UV light (365 nm). The study was carried out with particular attention to the ground state bleaching signals, directly connected to the formation of intragap...

Violins are complex wooden musical instruments, whose quality is mainly evaluated on the basis of their aesthetics, as well as depending on the historical relevance of their makers. However their acoustic quality remains a key evaluation parameter for performers and listeners. The instrument perceived quality, in turn, depends, on one side, on the player, the environmental conditions and on the listeners’ psychoacoustic factors. On the other side, the quality of a violin depends on its materials, constructive and setup parameters, that impact on the vibro-acoustical characteristics of the...

The present paper belongs to a line of research known as aerial archaeology and compares some specific visualizations of LIDAR data (hillshading, openness, and sky view factor) to understand which of them can provide the best approach to suitably identify and unveil some archaeological permanences as function of different boundary conditions. In the present case, such permanences belong to the very special material heritage consisting of the physical traces of the Great War, although latent, they persist in the present landscapes at different states of preservation and visibility, waiting to...
