If non-invasive analytical techniques, such as spectroscopies, could provide issues with overinterpretation of the data, chromatographic techniques combined with various detectors may be more suitable for separating and identifying the different components within a complex matrix, like archaeological pottery.

It employed ultrasound-assisted liquid extraction and dispersive liquid-liquid microextraction (dLLME). dLLME allowed to remove compounds that induce signal suppression, thereby minimizing the matrix effect.

The National Gallery of Denmark has witnessed an alarming acceleration of this phenomenon since the early 2000s, with lead white highlights in numerous old master drawings undergoing rapid discolouration. This study investigated the factors contributing to the darkening of lead white, specifically comparing industrially manufactured pigments to historically reproduced ones. The research aimed to determine if modern lead white, typically characterised by a higher proportion of hydrocerussite to cerussite in its composition, is more susceptible to darkening. Lead white paint mock-ups were subjected to hydrogen sulfide exposure under varying environmental (such as temperature and relative humidity levels) and material (such as pigment and binder properties) conditions to examine their impact on pigment stability. Due to the extensive number of variables involved, the investigation focused on a subset of the possible experimental conditions. The results indicated that modern lead white is more prone to rapid darkening, likely due to increased lead hydroxide content and smaller particle size, leading to higher reactivity with hydrogen sulfide. Additionally, the pigment-to-binder ratio significantly influenced darkening, with high ratios exacerbating the issue for both industrially made and historically reproduced pigments. Although temperature and relative humidity had minimal direct effects, elevated temperature and humidity conditions could potentially accelerate deterioration by hastening chemical reactions and promoting hydrogen sulfide dissociation into more reactive ionic species, respectively, thus increasing lead white vulnerability to darkening. However, given the observed greater influence of chemical and structural properties over environmental physical factors in the darkening of lead white, these findings emphasise the crucial role of pollution control and suggest that effective preservation of artworks and historical artefacts containing lead white highlights should prioritise strategies to reduce hydrogen sulfide exposure, rather than solely relying on climate control measures.</div></div>","PeriodicalId":15480,"journal":{"name":"Journal of Cultural Heritage","volume":"71 ","pages":"Pages 137-144"},"PeriodicalIF":3.5,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142746100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Collecting, managing, visualizing, and sharing this information requires standardization. In the last decades, architecture has advanced in information management with the implementation of Building Information Modelling (BIM) methodology. The application of this methodology to cultural heritage has associated challenges due to the complexity and heterogeneity of the information. The integration of ontologies and BIM allows obtaining semantically enriched digital models, which has led to a growing interest in the field of architectural cultural heritage. In this article, the Cultural Heritage Earthquake Damage Ontology (CHEDO) model is presented. This ontology has been designed to document damage and loss caused by earthquakes in cultural heritage, through its integration into BIM systems interconnected with databases, although this integration is not addressed in the present work. The CHEDO model integrates terms and relationships to document the damage process in relation to the building characteristics (architectural, spatial, constructional, and geometrical) and the physical environment of the same. This model, by providing a comprehensive description of the building and its environment, allows for complete and accurate documentation of damage, which supports the planning of post-earthquake restoration and reconstruction. To facilitate interoperability with parallel ontologies in close domains of architectural cultural heritage, CHEDO was designed taking as reference the high-level ontology Conceptual Reference Model (CRM) developed by the International Committee for Documentation (CIDOC), of the International Council of Museums (ICOM). The proposed ontology is structured in four blocks: <em>'building and surrounding environment'</em>, to describe the building and its environment; <em>'building damage</em>', to represent the damage and its causes; '<em>location</em>', to describe the location of the building and the external processes; and '<em>terminology</em>', to categorise and classify certain classes of the ontology.</div></div>","PeriodicalId":15480,"journal":{"name":"Journal of Cultural Heritage","volume":"71 ","pages":"Pages 114-126"},"PeriodicalIF":3.5,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142746097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Indeed, cellulose—the primary material of these artifacts— goes through irreversible degradation processes as it ages, leading to a weakening of paper stability and color changes. In order to slow down ageing, several restoration strategies involving the use of wet cleaning by hydrogels can be found in literature. Multi-step treatments are often required to complete the cleaning procedure, as the properties of contaminants greatly vary from a chemical–physical point of view (i.e. hydrophilic, hydrophobic or, as for adhesives, polymeric compounds). In this article, we propose a cleaning strategy that accounts for the inherent roughness of paper by developing microgel particles made of methacrylated gellan gum. Microgel particles are smaller than their macroscopic counterparts, hydrogels, and as a result, they can clean paper more quickly, a few minutes as opposed to hours. Moreover, the chemical modification performed on deacylated gellan gum makes the polymer more hydrophobic, as compared to the unmodified one. In this way, the proposed microgels are able to interact with and adsorb not only hydrophilic by-products of cellulose degradation, as gellan gum-based microgels do, but also hydrophobic materials or synthetic adhesives. This procedure represents a valid strategy, safe for operators, for the cleaning of paper artworks as it avoids the use of potentially dangerous organic solvents for hydrophobic material removal.</div></div>","PeriodicalId":15480,"journal":{"name":"Journal of Cultural Heritage","volume":"71 ","pages":"Pages 97-105"},"PeriodicalIF":3.5,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142704192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
