Spectral imaging technology, widely used in remote sensing applications, such as satellite or radar imaging, has recently gained importance the field of artwork conservation. In particular, multispectral near-infrared region (NIR) proved useful analyzing ancient paintings because transparency most pigments and their varied reflectance changes over this spectral region. A variety systems, with different detectors filtering dispersing technologies, have been implemented. Despite recognized...
Abstract Nonlinear optical microscopies are widely used in the biological and biomedical fields, as they non-invasive techniques that permit safe structural morphological characterisation of cells tissues. They increasingly being Cultural Heritage field because their ability to overcome some limits well-established techniques. However, since nonlinear use pulsed laser sources with high peak power, application raises concerns due artworks' unique, priceless, delicate nature. In this paper, we...
The early detection of bronze disease is a significant challenge not only in conservation science but also various industrial fields that utilize copper alloys (i.e., shipbuilding and construction). Due to the aggressive nature this corrosion pathway, developing methods for its pivotal. presence trihydroxychlorides main key indicator ongoing autocatalytic process. Commonly used pigment identification, reflectance imaging spectroscopy (RIS) or fiber optics (FORS) was recently employed mapping...
Abstract Infrared reflectography is a well-known technique based on wideband imaging in the near-infrared (NIR) range used for painting diagnostics conservation laboratories.. This work focused application of multiband analysis pictorial layers and differentiated detection features. generates set narrowband NIR images painting. Starting from dataset that registered, metrically correct, calibrated, capability collecting both spectral spatial information has been exploited by processing image...
Abstract Organo- and hydrogels have been proposed in the restoration field to treat different types of surfaces. The possibility retain solvents a controlled superficial action allowed use these materials for removal very thin layers applied on ancient historical objects, when under paint are particularly delicate water sensitive. In last years, an increased attention has devoted proposal more healthy products guarantee safeguard operators. Few development green methods which foresee...

Calcium oxalates are insoluble colorless or whitish salts constituting noble patina, on both natural and artificial stone artworks' surfaces, the presence of which is extremely valued. The not considered detrimental to substrate, however, being often accompanied by other substances such as gypsum, silicates, pigmented particles. They may form very adherent, relatively thick colored layers creating disfiguring effects hindering legibility pictorial surface. For this reason it be appropriate...
Alchemy (1947, Peggy Guggenheim Collection, Venice) is one of the most materic works by J. Pollock, whose palette extensive, ranging from white to yellow, red, green, violet, blue, black, and silver. Each layer color was laid on top a previously dried effectively separated lower forming quite complex stratigraphy with colors intersecting each other. In this study, non-invasive multi-technique method combining point analysis Vis–NIR multispectral imaging has been exploited give insights...
A concise insight into the outputs provided by latest prototype of visible-near infrared (Vis-NIR) multispectral scanner (National Research Council-National Institute Optics, CNR-INO, Italy) is presented. The analytical data acquired on an oil painting Madonna Rabbit É. Manet are described. In this work, Vis-NIR was complemented with X-ray fluorescence (XRF) mapping for chemical and spatial characterization several pigments. spatially registered facilitated their processing spectral...
Abstract The identification of textile fibres from cultural property provides information about the object's technology. Today, microscopic examination remains preferred method, and molecular spectroscopies (e.g. Fourier transform infrared (FTIR) Raman spectroscopies) can complement it but may present some limitations. To avoid sampling, non-invasive fibre optics reflectance spectroscopy (FORS) in near-infrared (NIR) range showed promising results for identifying fibres; examining...
A major challenge in heritage science is the non-invasive cross-sectional analysis of paintings. When low-energy probes are used, presence opaque media can significantly hinder penetration incident radiation, as well collection backscattered signal. Currently, no technique capable uniquely and noninvasively measuring micrometric thickness heterogeneous materials, such pictorial layers, for any painting material. The aim this work was to explore possibility extracting stratigraphic...
We report on tests to remove naturally and artificially aged shellac varnish by laser traditional chemical cleaning from the substrates of mural paintings. Optical tools were used for evaluation processes, in particular microprofilometry assess changes surface morphology time-domain confocal optical coherence tomography (OCT) evaluate thickness. The assessment was integrated with molecular characterization provided portable Fourier transform infrared spectroscopy operating reflectance mode,...
Dry and wet drawing materials were investigated by THz time-domain spectroscopy in transmission mode. Carbon-based iron-gall inks have been studied, some prepared following ancient recipes others using current synthetic materials; a commercial ink was studied as well. We measured the signals on thin film of liquid deposited polyethylene pellicles, comparing results with thick pellets dried blended powder. This study required implementation new experimental method data analysis procedure able...
Paintings are complex multi-layered structures characterised by high compositional and structural heterogeneity. Therefore, a combined analytical approach is often required to overcome ambiguities in the interpretation of data acquired an individual technique. In this paper, we applied three non-invasive imaging techniques for study 14th-century altarpiece Pietro Lorenzetti belonging Uffizi Galleries. detail, used reflectance spectroscopy identify map pigments, reveal features not visible...
Preserving and analytically examining daguerreotypes is particularly challenging because of their multi-material multi-component structure. Various sensors have been exploited to examine mainly the image plates even though degradation goes beyond this component. Micro-analyses preferred method due nanoscale structure particles. In work, we propose comprehensive multi-modal non-invasive sensing investigate corrosion products present in nine from Fondazione Alinari per la Fotografia (FAF,...
Copper alloy artworks are particularly subjected to chloride attack, which may trigger bronze disease. Therefore, early identification of the phenomenon is crucial in order stabilize reactive copper (CuCl) and remove harmful corrosion products (atacamite polymorphs). Confocal Raman Microspectroscopy (CRM) has proven be effective for detection small amounts atacamite, ascribable initial phases corrosion. The handling often difficult or even impossible given their large size weight, sampling...
