The present paper focuses on the reflectance spectral imaging of painted surfaces in visible-near infrared region (400–2500 nm). Other ranges and methods are mentioned, to contextualize investigation works art.
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 In this project, micro‐Raman (µ‐Raman) spectroscopy has been used as a means to investigate the pigments employed in decoration of Anasazi pottery. Analysis Raman spectra revealed presence organic‐ (amorphous carbon), iron‐ and/or manganese‐based line with known pictorial materials by people. The results were also complemented studies employing scanning electron microscope equipped microanalysis energy dispersive X‐ray detection (SEM/EDX) system, which proved helpful mainly while...
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...
Copper resinate is a green pigment widely used by the 16th century painters, as many surveys on Italian and European paintings proved. The transparent glaze, its color due to copper salts of resin acids. oldest recipes suggest preparation mixing verdigris with terpenic resins Venice turpentine (conifer resins) hot ashes. detection in up this time an analytical challenge. We examined Raman features (powder mock paint film linseed oil) compared them verdigris. Six laser sources (488, 514, 532,...
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...
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...
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,...
Abstract Stratigraphic analyzes of polychrome surfaces, such as paintings, often need samples to offer consistent results regarding the sequence and composition layers. Non-invasive methodologies based on linear nonlinear optical techniques limit material removal from objects. Recently, coherence tomography (OCT) has become preferred choice heritage scientists because it is a safe fast alternative for studying transparent or semi-transparent Yet, microscopy (NLOM)) technique in its modality...
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...
Laser cleaning of bronze artefacts is a very promising conservation approach and its wider distribution would benefit from further studies advantages drawbacks. Some important references are available, yet laser cannot be considered traditional method for surfaces. In this paper, we report on the evaluation tests performed an statue Napoleon, depicted as Mars Peacemaker, cast by Righetti in 1811 after model Antonio Canova. The sculpture exposed to outdoor environment main courtyard Brera...
We present a method for estimating the thickness of thin turbid layers using defocusing micro-spatially offset Raman spectroscopy (micro-SORS). The approach, applicable to highly systems, enables one predict depths in excess those accessible with conventional microscopy. technique can be used, example, establish paint layer on cultural heritage objects, such as panel canvases, mural paintings, painted statues and decorated objects. Other applications include analysis polymer, biological...
