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.
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...
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...
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...
Modern and contemporary artworks, due to technological developments in the synthesis of new pigments, are characterized by a pictorial palette composed wide variety pigments. This diversity makes it increasingly important carry out thorough characterization studies order gain complete comprehensive understanding properties numerous pigments use today. In this work, 18 modern acrylic paints were using micro-Raman spectroscopy with two laser excitation lines (532 nm 633 nm). The analysed can...
Raman spectroscopy (RS), for its robust analytical capabilities under constant development, is a powerful method the identification of various materials, in particular pigments cultural heritage. Characterization artist’s palette fundamental importance correct formulation restoration intervention as well preventive conservation artworks. Here we examine number and variability research studies exploiting Bravo handheld spectrophotometer relying on excitation signal with temperature-shifted...
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...
Daguerreotypes are the first widely disseminated photographic process made public in half of 19th century. Their invention and development closely related to a network scientists, primarily physicists chemists, whose interest light its phenomena significantly contributed advancement techniques. This contribution traces history daguerreotypy through figures these opening window onto fascinating chapter science.
The characterization and conservation of materials constituting contemporary art pose a significant challenge for scientists restorers due to the wide variability heterogeneity in their compositions chemical instability. aim this study is contribute understanding composition ageing artworks, specifically Analytical Painting. To purpose we examine an acrylic painting on raw canvas, Tela by Giorgio Griffa (1973), model samples purposely prepared together with painter. Felt‐tip marker vandalic...
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,...
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...
