Tourism activity in general, with the heritage tourism sector in particular, represented the second inflow of foreign currency to Mexico in 2019 (pre-pandemic), with more than USD 24 million. According to local polls, the main purpose of travel is leisure. However, more than half of tourists (local and foreigner) who visit Mexico enjoy/visit an archaeological site, a museum, and/or a local community. The latter illustrates that the heritage tourism sector is a vital axis within the national and local economy, as well as to promote its research, conservation, and diffusion. Researchers claim that it can also be an important component for the cultural revitalization of communities. However, how well does a community benefit from the tourist activity of any particular heritage/archaeological site? Can they feel any connection with it if only a handful of community members benefit from it? Using the Cancun example, we will talk about the concept of “heritage tourism”, not only for its economic value but also for its potential for social/cultural assessments for local heritage. Secondly, we talk about how archaeology is performed and how pre-Hispanic sites play along as a tourist attraction, particularly from the Mexican perspective. Full article

A library cataloguing the electron paramagnetic resonance (EPR) spectra of artists’ pigments has been created. It contains spectral data collected using several spectrometers that operate at different frequencies for, currently, 51 pigments. The library is intended to serve as an open-access reference database for the scientific studies of cultural heritage objects that utilize this analytical technique. Furthermore, it is a living repository, in that entries will be added as more pigments found to have EPR signals at room temperature are studied. Because EPR is less well established in the field of heritage science than some other common spectroscopies, this companion paper serves as an educational supplement to the library. It focuses on first, describing the theory of EPR to the level necessary to understand the origins of spectral features and to utilize these for pigment identification, and then, on discussing the organization of the library to facilitate the navigation of its contents.

Over the last two decades, scholars and organizations across the world have carried out research projects and promoted dissemination tools aimed at promoting food and food-related elements embedded in local and traditional foodways. In this regard, the documentation of food and biocultural heritage has been seen as the starting point of processes directed toward their safeguarding and promotion. Drawing from this premise, the paper presents an original methodological approach, designed within the framework of the Ark of Taste project, to map, inventory, and document food and food-related resources to produce a comprehensive dissemination tool for the promotion of local food and biocultural heritage. To this end, the paper discusses the case study of the Atlas of the Ark of Taste in Tanzania, looking at the approach used, and the challenges faced, in undertaking field and desk activities aimed at inventorying Tanzanian food products and in the creating of the gastronomic atlas of this country. Drawing from this experience, the paper highlights the potentially crucial role that food and gastronomic inventories may have in achieving UN Sustainable Development Goals from a grassroots perspective. Acknowledging the limitations and possible unintended effects of these initiatives on the protection of food and biocultural resources, the authors recognize the promising role that these tools could have in fostering the achievement of environmental (SDGs 13, 14, 15) and social sustainability (SDGs 1, 2, 3, 10) objectives.

In 2021, two projects for the protection and preservation of Austrian stained glass were performed in close cooperation between the Federal Monuments Authority Austria and active members of the Corpus Vitrearum Austria. Both projects are dedicated to difficult topics that will increasingly challenge how we tackle the preservation of monuments in the coming decades. There are questions regarding the correct conservation and restoration treatment of stained glass from the late 19th and early 20th century (stained glass from the so-called art period of Historicism), which, despite all the Guidelines for the Conservation and Restoration of this endangered genre of art, is still far from being treated with the necessary care throughout the country. The protection and preservation of the original substance—the glass, the leading and the painting—are the primary focus of interest here. Using the example of the restoration campaign currently being conducted on the windows of St. Mary’s Cathedral, Linz, a cultural monument of particular importance for Austria, work is being undertaken to elaborate the feasibility of a concept that can be easily implemented in the future at other construction sites and by all the stakeholders involved. The second monitoring project presented concerns the equally important area of “preventive conservation” of medieval and modern stained glass. The focus of the work that took place here was on checking the condition of stained glass from the Middle Ages to the 20th century (with and without exterior protective glazing) and the general identification of damage and determination of the urgency of measures for conservation (using a “traffic light system” developed for this purpose).

Gandharan art developed in the Himalayan area in the early centuries CE. It has been investigated mostly from an iconographic point of view, missing, until very recently, a systematic technical investigation of materials and techniques. Recently our team began performing chemical analyses of the traces of the polychromy originally covering statues, reliefs and architectural decorations, to discover the ancient painting techniques and artistic technologies. This paper presents the results of the analytical investigation (optical microscopy, Raman spectroscopy and gas chromatography coupled with mass spectrometry) of pigments, ground layers and binders of a new group of samples taken from stucco architectural decorations (2nd–3rd/4th centuries CE). The samples were collected directly at an archaeological site in the Swat Valley, ensuring the exact knowledge of their stratigraphic provenance, as well as the absence of any restoration treatment applied prior sampling. The results are discussed in the wider context of Gandharan polychromy investigated so far by our team, as found in sculptures and architectural decorations preserved in museums (in Italy and France) and in archaeological excavations in Pakistan. The aim of this research is to shed light on the materials and techniques of this Buddhist ancient art from this region and on the influences exerted on it from Eastern and Western artistic traditions.

In this paper, a representation based on digital assets and semantic annotations is established for Traditional Craft instances, in a way that captures their socio-historic context and preserves both their tangible and intangible Cultural Heritage dimensions. These meaningful and documented experiential presentations are delivered to the target audience through narratives that address a range of uses, including personalized storytelling, interactive Augmented Reality (AR), augmented physical artifacts, Mixed Reality (MR) exhibitions, and the Web. The provided engaging cultural experiences have the potential to have an impact on interest growth and tourism, which can support Traditional Craft communities and institutions. A secondary impact is the attraction of new apprentices through training and demonstrations that guarantee long-term preservation. The proposed approach is demonstrated in the context of textile manufacturing as practiced by the community of the Haus der Seidenkultur, a former silk factory that was turned into a museum where the traditional craft of Jacquard weaving is still practiced.

This work regards the representation of handicrafts for craft training and demonstration in the environment of an ethnographic heritage museum. The craft of mastic cultivation is chosen as a use case. This paper presents the process of representation and presentation of this craft, following an articulated pipeline approach for data collection, annotation, and semantic representation. The outcomes were used to implement an exhibition that targets the presentation of craft context and craft training, through interactive experiences, mobile applications, and a hands-on training where users reenact the gestures of a mastic cultivator. Preliminary evaluation results show high acceptance for the installation and increased user interest. Full article

Francisco Conde-Valvís’s so-called “stone treasure” is a set of unique carved stone pieces, such as bases, column shafts, a mortar, and decorated fragments (trisqueles and rosettes), found during the 2018 excavation campaign in the Cibdá de Armea (Allariz, Ourense). They had been piled up and re-buried—no records existed as to where—at the western end of the Finca de A Atalaia, which was excavated in the 1950s under the direction of Conde-Valvís and began to be excavated again in 2011. The thorough review of the graphic and textual material available from the old excavations allowed us to determine the original archaeological context of the pieces. Most of these elements belonged to the atria of the so-called “Domus of Hexasquel” (North house) and “Domus of the Rosette” (South house). Once we established the origin of all the elements, especially with the aid of the old photographs, it was decided to reintegrate them into the site, to increase the educational and interpretive value of Armea, instead of burying them indefinitely in the warehouses of a museum.

The vernacular architecture in many regions in Eastern Austria was characterized by the use of unfired clay, at least until the 19th century, and in some areas until the 20th century. Farmhouses and associated farm buildings, such as storage buildings or press houses for the production of wine and cider, were erected using different earth construction techniques. The study area stretches from the Weinviertel, a region located in the province of Lower Austria in the north-east of Austria, to the Burgenland, a region located in the south-east of Austria, which belonged to Western Hungary until 1921. From a geological point of view, in the east of Austria—in the Vienna Basin and the Molasse Zone—huge areas of Tertiary clay are covered with loess deposits, which is the best-known basic material used in local earth-building traditions. A core question in the research on vernacular earthen heritage focuses on the impact of the geological conditions in Eastern Austria on the local earth-building techniques. The mineralogical composition of the different clays had an impact on the local building techniques. From a material-culture point of view, research on the relationship between the mineralogical properties of clay resources and local building techniques sheds light on the factors which influenced the evolution of certain vernacular building features. Tertiary clays and loess from the Pleistocene favoured the making of earth lumps, cob walls and adobe bricks over the whole Eastern Austrian region. Contrarily, regions in Burgenland with a high amount of gravel preferred, by tradition, to make walls by ramming. The clay mineral smectite acts as a binding agent in earth-building techniques over the whole investigated region—Weinviertel, Burgenland and Western Hungary. Full article

Several different types of burial were identified during the excavation of the Roman military cemetery associated with the fort at Birdoswald, on Hadrian’s Wall (UK). Fragments of glass vessels and glass beads were recovered from many of the cremation deposits, as they were commonly used during cremation rituals, and many of these had been affected by heat. X-ray fluorescence spectroscopy and scanning electron microscopy were used to investigate the raw materials, colorants and opacifiers employed to produce the glass assemblage. Most of the large fragments are transparent with a blue-green colour, with a composition typical of recycled glass. The smaller fragments are from beads and are coloured and sometimes opaque. Colourants and opacifiers characteristic of Roman glass were added in this glass formulation, including cobalt-based compounds (blue glass), copper alloys (green glass), white calcium antimonate, and yellow lead antimonate. The multianalytical approach of this research has allowed for the distinguishing of the extreme depletion of sodium on the surface of the melted glass fragments due to the exposure to high temperatures during the cremation process, followed by surface weathering in a burial environment. Based on the chemical composition of the bulk of the samples, a model of high temperature viscosity of glass was applied in order to assess the cremation temperature in the pyre, providing relevant information about funerary rituals and cremation technology in Roman Britain.

In this paper, we present the ⁸⁷Sr/⁸⁶Sr data of 13 samples from horses from six Lithuanian burial sites dating from the 3rd to the 7th C AD. Alongside these data, we also publish the bioavailable ⁸⁷Sr/⁸⁶Sr data of 15 Lithuanian archaeological sites, based on 41 animals which enabled the construction of a reliable baseline for the Southeast Baltic area. The ⁸⁷Sr/⁸⁶Sr values partially confirmed the hypothesis that the unusually large horses found in Late Roman Period to Post-Migration Period burials are of non-local origin. Of the three non-local horses identified, two were among the largest specimens. However, the overlap of bioavailable ⁸⁷Sr/⁸⁶Sr data across different European regions does not permit us to establish whether the non-local horses originated from other areas in Lithuania or from more distant regions. With regards to the ⁸⁷Sr/⁸⁶Sr data, the place of origin of the non-local horses could be Southern Sweden. This encourages discussions on the possible directions of migration and compels us to rethink the current models that posit South and Central Europe as the main sources of migration. The results of the ⁸⁷Sr/⁸⁶Sr, δ¹³C, and δ¹⁵N analyses demonstrate that horses buried in the same cemetery had different mobility and feeding patterns. Differences could be due to the different function and sex of the horses as well as the lifestyle of their owners. The most sedentary horses were pregnant mares, while the extremely high δ¹⁵N of three horses may reflect additional fodder and probably a better diet. Full article

In Roman Baths, the Romans employed barrel and groin vaults of great dimensions, with maximum span more than 20 m; simple tools of structural analysis of ancient wide span vaulted halls are still lacking, due to geometrical and material complexity. In this paper, we study the collapse behavior, under horizontal static action, of a corner cross vault of the Baths of Diocletian in Rome (Hall I). Two methods of analysis are here used: non-linear incremental finite element and limit analysis. In both cases, 3D models have been developed by means of UAV inspection, NDT measures, and AVT monitoring. The construction of the overall 3D geometry has been here afforded with a specific pre-processing approach. Midas commercial software has been employed for FEM analysis, assuming a constitutive law specifically developed for Roman concrete. In limit analysis, masonry is discretized as a system of interacting rigid bodies in no-tension and frictional contact. The computational code consists in a linear approach, which makes use of a series of optimization packages via lower and upper bound techniques. Finally, a strategy based on FEM analysis including discontinuities was implemented, and the results were compared with the two previous approaches. Full article

Biocultural heritage preservation relies on ethnobotanical knowledge and the paleoethnobotanical data used in (re)constructing histories of human–biota interactions. Biocultural heritage, defined as the knowledge and practices of Indigenous and local peoples and their biological relatives, is often guarded information, meant for specific audiences and withheld from other social circles. As such, these forms of heritage and knowledge must also be included in the ongoing data sovereignty discussions and movement. In this paper we share the process and design decisions behind creating an online database for ethnobotanical knowledge and associated paleoethnobotanical data, using a content management system designed to foreground Indigenous and local perspectives. Our main purpose is to suggest that the Mukurtu content management system, originally designed for physical items of cultural importance, be considered as a potential tool for digitizing and ethically circulating biocultural heritage, including paleoethnobotanical resources. With this database, we aim to create access to biocultural heritage and paleoethnobotanical considerations for a variety of audiences while also respecting the protected and sensitive natures of Indigenous and local knowledges.

In recent decades, many works have been devoted to the study of materials and painting techniques used to produce illuminated manuscripts. If the analyses were once largely invasive, the approach has become increasingly more in situ and non-invasive over the years. This work presents the results of the analysis of the Portuguese Charter of Évora, an illuminated manuscript that dates back to 1501, combining an elemental mapping technique (MA-XRF) with the non-invasive imaging techniques of infrared reflectography and digital microscopy. Remarkably, this approach allowed us to obtain unexpected results regarding the chronology of production of the illumination of the view of the City of Évora and of the Charter of Évora itself, posing new questions for art history on the political, social and artistic context of the early 16th century City of Évora.

In the framework of the IH-AT (Invisible Heritage Analysis and Technology) project, a cluster of churches ranging from the 11th to the 16th centuries, located in the Troodos Mountain range of Cyprus, designated by UNESCO as World Heritage monuments, were investigated using Non-Destructive-Techniques (NDT) (geophysical and topographic survey), 3D modelling and visualisation methods, contextualised and interpreted by art-historical and archaeological research. A geophysical survey, performed using a Ground Penetrating Radar (GPR), specifically aimed to confirm the presence or absence of buried features of archaeological interest at each of these sites, in particular, evidence of monastic complexes and buildings that used to surround preserved churches. This paper describes the preliminary results of this survey and some initial interpretations concerning what new information can be discerned about the now lost monastery complexes, in advance of future excavation.

Six rare porcelains of the Qing Dynasty, in particular, dishes ordered respectively for Philibert Orry, the Duke of Penthièvre and a tureen from the service of Louis XV, with royal coat-of-arms, were analyzed non-invasively by Raman microspectrometry. A coffee pot with a rare decoration attributed to Cornelius Pronk was also analyzed as well as two plates, one decorated with an Imari-style pattern and the second post-decorated in the Low-Countries/Holland. The enamel types and coloring or opacifying agents were identified on the basis of combined Raman and SEM-EDXS analysis previously published as well as new section and surface analysis of five plate samples representative of different technologies (blue-and-white, Famille rose). The use of lead oxide for the preparation of overglaze is demonstrated. For the first time, the use of borax in the blue overglaze according to the recipe from the 1753 manuscripts of French chemist Jean Hellot is demonstrated on Chinese porcelain. This fact, like the use of cobalt free of manganese, demonstrates the use of European ingredients and/or recipes for ceramics exported from China to Europe. The highlighting of the use of different recipes or raw materials for porcelain from the same period can therefore be the signature of different workshops. For instance, three different Raman signatures of red decoration were identified from the hematite vibration modes: very narrow modes for Pronk’ coffee pot and Louis XV tureen, broad for Orry’ dish and intermediate for the others. Three workshops are thus expected. It is interesting to note that the use of arsenic for the realization of white enamels corresponds to the latest objects, made after 1738. China was therefore in the 18th century both an importer of European know-how, design and an exporter of enameled products made with imported technologies to Europe. Full article

In this paper, two different objects from the ethnographic collection of the museum of the Congregation of the Sacred Hearts of Jesus and Mary (Rome), a Polynesian barkcloth (tapa) and a Polynesian headdress in feathers (pa’e ku’a), were investigated to characterize the materials, to evaluate their state of conservation and address the restoration activities. Imaging methods such as multispectral imaging, 3D ultraviolet induced fluorescence and scanning electron microscopy have been integrated with analytical techniques such as X-ray fluorescence spectroscopy, Fourier transform infrared and surface enhanced Raman spectroscopy. Imaging investigations allowed us to differentiate constitutive materials and study their distribution, such as the yellow dye in the tapa used to trace the geometrical pattern and the psittacofulvins responsible for the feathers’ colors in the headdress. The combination of molecular spectroscopy, supported by observation under a scanning electron microscope, allowed us to propose a characterization of the organic painting materials (Morinda citrifolia, Curcuma longa) used for the tapa, and of the type of feathers (from Vini kuhlii bird) and vegetal fibers (Cocos nucifera L.) used to realize the headdress, as well as enabling the identification of degradation products and microorganisms affecting the artifacts before restoration. Fourier transform infrared spectroscopy detected the organic materials used as adhesives for the tapa and headdress: a polysaccharide, probably starch, for the tapa and a natural rubber from Cerbera manghas L. for the headdress. The results of the multi-analytic diagnostic campaign enabled the choice of proper restoration materials, compatible with the original ones, and helped us develop effective protocols for the artifacts’ conservation, such as laser cleaning of the feathers.

Museums increasingly recognize the need to address advances in digital culture which impact the expectations and needs of their audiences. Museum collections of real objects need to be presented both on their own premises and digitally online, especially as digital and social media becomes more and more influential in people’s everyday lives. From interdisciplinary perspectives across digital culture, art, and technology, we investigate these challenges magnified by advances in digital and computational media and culture, looking particularly at recent and relevant reports on changes in the ways museums interact with the public. We focus on human digital behavior, experience, and interaction in museums in the context of art, artists, and human engagement with art, using the observational perspectives of the authors as a basis for discussion. Our research shows that the COVID-19 pandemic has accelerated many of the changes driving museum transformation, about which this paper presents a landscape view of its characteristics and challenges. Our evidence shows that museums will need to be more prepared than ever to adapt to unabated technological advances set in the midst of cultural and social revolution, now intrinsic to the digital landscape in which museums are inevitably connected and participating across the global digital ecosystem where they inevitably find themselves entrenched, underscoring the central importance of an inclusive integrative museum model between physical and digital reality.

We report on the interpretation of a late medieval Eastern Mediterranean glazed ceramic vessel with sgraffito decoration depicting a sailing ship. The artefact represents a chance find that was recovered outside the excavation area of the Ropotamo underwater archaeological excavations on the Southern Bulgarian Black Sea Coast in 2017. Fragments of late medieval sgraffito-decorated ceramics with depictions of sailing ships are rare. Complete examples can be considered exceptional. The Ropotamo artefact is of particular interest due to the freehand execution of its decoration, which suggests some understanding of contemporary ship proportions and seafaring practices on behalf of the artisan. The specimen is analyzed against similar artefacts and discussed in the context of maritime graffiti from the Black Sea and Eastern Mediterranean regions. The aim is to establish its potential for studying archaeological ceramics and evaluate the extent to which the decoration reflects aspects of Eastern Mediterranean maritime culture of the late Byzantine and early post-Byzantine periods. More research is required to appreciate the full potential of the Ropotamo artefact. A hypothesis for origin, dating and significance has been proposed. However, due to a shortage of published parallels, it may be subject to further refinements in the future in case more stratified similis are identified. Full article

This paper presents the results of a study on the quadruple flutes (multiple pipes) from the UNESCO World Heritage Centre of Teotihuacan, Mexico, based on a thorough examination of the fragmented, restored and partly reconstructed archaeological finds and the manufacture and subsequent test of a series of playable reproductions with a refined reconstructive design. For the latter, organological features, such as the diameter, number and position of the fingerholes/tone holes and the length of the individual pipes of the restored finds are challenged and a new design is proposed that might be closer to the original construction of the Teotihuacan instruments. The study reveals a better understanding of the particular construction, acoustics and musical possibilities of the Teotihuacan quadruple flutes. Full article

This paper reports the analyses carried out on the medieval copper alloy door (1111–1118 AD) of the mausoleum of Boemondo d’Altavilla in Canosa di Puglia (Southern Italy). The studied door is the smallest medieval bronze door extant in Italy and, unlike the other Byzantine doors, was most probably made in Canosa di Puglia and not in Constantinople. Analyses were performed to assess the chemical composition of the alloy patinas using a portable energy dispersive X-ray fluorescence (ED-XRF) instrument designed at the University of Salento. The experimental results suggested that the two door leaves have the same chemical composition, even if they appear different in both style and size. Furthermore, the alloy used for the door is different from the other previously-analyzed Byzantine bronze doors. The obtained results can be used in the future to compare the chemical composition of other Byzantine doors in order to better understand the manufacture of these precious artifacts. Full article

The cemetery is a cultural landscape that represents themes of great relevance to interpret the structure of a society, roles, and hierarchies, as a reflection of its social life. The cemetery gathers a whole symbolic universe where local social histories are represented, beyond the history of art and the architectural aspect. As a heritage element, the cemetery shows us the socio-cultural changes of a territory: religious questioning, changes linked to the family, individualization of contemporary society or broader questions about socio-economic structure. This article presents the experience conducted during the last 6 years in the Cemetery “Nuestro Padre Jesús” in Murcia (Spain), through a collaboration among the Sociedad Murciana de Antropolgía (SOMA), the University of Murcia and the Municipality of Murcia, developing the project “Funerary Cultures”, whose main objective is to promote the heritage, cultural and historical values of the funerary culture. Specifically, as a result of this teaching innovation experience, the six thematic guides to visit the cemetery are presented as an experience of patrimonialization of elements of the cemetery and its consequent selection and consensus exercise to determine what was considered as heritage in the context of the cemetery. Finally, a proposal of a systematic process in the valuation and selection of the material objects in the cemetery is presented; this proposal allows us to establish a debate on what considerations to take into account when considering the relationship between cultural heritage and the cemetery as a cultural landscape in permanent transformation.

Traditional crafts exhibit tangible and intangible dimensions. Intangible dimensions include the practitioner’s gestural know-how in craft practice and have received smaller attention than tangible dimensions in digitization projects. This work presents the process of representation and presentation of the glasswork and is exemplified in the re-creation of a historical object. Following an articulated pipeline approach for data collection, annotation, the crafting process is represented visually and semantically in a way that can be meaningfully presented and utilized in craft training and preservation. The outcomes of the proposed approach were used to implement a Mixed Reality installation. The installation targets craft presentation through an exploration of the workspace, as well as craft training through an interactive experience where users re-enact gestures of a glass master holding a tool and receiving audiovisual feedback on the accuracy of their performance. Preliminary evaluation results show high acceptance of the installation and increased user interest. Full article

The invention of European hard porcelain, which aims at imitating kaolin-containing white paste of Chinese porcelain, had been started by the development of the technology of “red porcelain”, so-called “Jaspisporzellan” by Johann Friedrich Böttger in the early-eighteenth century at Meissen (Saxony). The visual features of the earlier Böttger red stoneware were rather similar to the one produced in Yixing, China. The prominence of Böttger productions allowed the manufacturing to be expanded across Europe to different countries (Holland, England, France, etc.). In this study, the chemical characteristics of nine European unglazed objects produced in England, France, Russia, and Holland from the 17th to 19th century and 10 Chinese (unglazed or enameled) red stoneware have been studied by using an on-site characterization technique pXRF. The results were compared with the previous studies carried out on 25 unglazed, polished, and non-polished Böttger artefacts. This non-invasive, speedy technique allows a methodology to be created for distinguishing the technological differences related to the provenance and authenticity of the artefacts. The elemental measurements explicitly show the significant discrepancy of Dutch objects from the main group, which involves other European and Chinese ones. Both a Lambertus van Eenhoorn (Delft) statue and an Ary de Milde (Delft) teapot are distinguishable from other European red stoneware by the high content of iron and calcium and high content of titanium and potassium, respectively, found in their body compositions. An overall comparison was made between the measurements made at different times in order to evaluate the error range arising from the measurement procedure (e.g., energy resolution of other series of the same instrument model).

Grouting of historic structures is a common procedure in many restoration projects, as the masonry in many cases requires additional strengthening. However, grouting of complex historic structures can also provide important information regarding the construction phases and the state of preservation of the internal structure of a monument, which may not be visible by the naked eye. This requires an innovative approach in order to reveal these aspects. In the current research, the data recorded from the grouting of the Holy Aedicule are implemented and analyzed, in order to obtain information regarding the construction phases of the complex Holy Aedicule structure, as well as information regarding the state of preservation of the internal structure behind the marble cladding that encloses it. The correlation of detailed grouting data with geospatial information allows for a more detailed analysis, which, coupled with ground-penetrating radar prospections, can provide critical information regarding the features of the internal structure. The results highlight the importance of this correlation to reveal information that may not be obtained through a typical approach. Thus, this study allowed for the development of an evolved interdisciplinary approach for the management of grouting data in a 2.5D environment, which can be applied in other historic structures and buildings.

Two paintings, made on aluminium support by Silvio Pasotti (among the major exponents of 1960s Italian pop art) were investigated in a totally non-invasive manner to identify the materials used by the artist. Raman spectroscopy, Fourier-transform infrared spectroscopy (FTIR), visible reflectance spectroscopy, and spectrofluorimetry with visible excitation were exploited as molecular analysis techniques, which are particularly suitable to recognise also synthetic organic materials, such as pigments and binders. The effectiveness of this multi-analytical approach was demonstrated, leading to the identification of several synthetic organic pigments, both conventional and “special effect” ones, introduced during the first half of the 20th century, as well as some well-established inorganic ones. Combining FTIR results both in the medium and near IR ranges, considerations regarding the binders employed by the artist could also be made, suggesting the use of both nitrocellulose and acrylic paints. Imaging techniques, such as IR reflectography, false colour IR, UV induced fluorescence, and portable microscopy, were also used to achieve a better knowledge of the painting practice. Full article
