As these pieces are composed of different materials and subjected to constant handling, they often exhibit severe degradation, posing as a challenge for its conservation and restoration. This case study is focused on a processional banner, presumably from the 18th century, depicting, on one side, Saint Michael Archangel and, on the other, Our Lady of the Rosary. The intervention was supported by several analytical techniques such as textile fibres analysis, optical microscopy (OM), scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS), X-ray fluorescence spectroscopy (XRF), and Fourier transform infrared spectroscopy (FTIR). The results provided a better insight on the technological features of the object.","PeriodicalId":55942,"journal":{"name":"Conservar Patrimonio","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42182294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was performed by combining in situ non-invasive methods (infrared reflectography, radiography, and EDXRF) and laboratory microanalytical techniques (micro-Raman, micro-FTIR, and SEM-EDS). Infrared reflectography revealed underdrawings, underpaintings, painting style, and execution methods. Analytical techniques allowed the identification of painting materials, such as gypsum, lead white, barium white, zinc white, yellow ochre, chrome yellow, zinc yellow, red ochre, vermilion, ultramarine blue, hematite, Mars red, and lamp black. This study provides valuable information on the academic nude paintings’ palette and its artistic production technique. Finally, it intends to continue a systematic analytical study of the Faculty of Fine Arts’ collection, allowing the characterization of Master painters, their students, and other authors.","PeriodicalId":55942,"journal":{"name":"Conservar Patrimonio","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49644394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Attractive to artists since its development in the 1930s, it became especially popular during the 1960s. In Portugal, knowledge about its use by artists and its condition is scarce. In this work, the main Portuguese art collections were surveyed with the goal of gaining an overview of the use of acrylic sheet in the Portuguese art context and its current condition. The paper describes the methodology used and the results obtained regarding 137 artworks by 69 different artists registered as containing acrylic. Results show that this material is being used by Portuguese artists at least since the 1960s. It has been used in several artistic forms, from painting and sculpture to photography, installation, objects/reliefs, and artist books. Most of the artworks were in good or fair condition. The main problems observed were dust and dirt deposits, abrasion, and scratches.","PeriodicalId":55942,"journal":{"name":"Conservar Patrimonio","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2021-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42622629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It became evident that new treatments to allow the flattening of rolled films were needed. Therefore, a conservation treatment was developed to unroll and restore the original flatness of the negatives under study. The main purpose of the treatment was to enable proper handling, digitization and storage of this collection. The developed procedure was based on a de-shrinking process (chamber with vapours of glycerol, acetone and water) adapted from the conservation of motion-picture film literature, combined with flattening under weights. This paper discusses the adopted methodology which allowed to achieve positive results.","PeriodicalId":55942,"journal":{"name":"Conservar Patrimonio","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2021-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49424970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The exposure to external agents causes degradation and, in some cases, detachment of these tiles. In the coastal area of Aveiro city (Portugal), the building's facades, exposed to adverse atmospheric conditions are in constant contact with aggressive agents, which cause the detachment of a significant amount of facade tiles. Within the scope of the SOS Azulejo Project, and in partnership with the University of Aveiro, Fábrica Centro Ciência Viva de Aveiro, the Prison of Aveiro and DDL Arg, this study encompasses the conservation of a tile facade, after degradation and detachment of the ceramic body.\u0000\u0000Several replicas of the tiles were made in the specific context of a training action that took place at the Aveiro Prison. The technical study was carried out to analyse the compatibility and reversibility of the mortars and ceramic tiles used. The mortars were tested in their fresh and hard state for consistency through spreading, flexural tensile strength, compressive strength, water absorption, and pull-off adhesion tests on bricks surfaces. The results were satisfactory and the replicated tiles were applied on a building’s facade on the National Tile Day, as part of an awareness campaign.","PeriodicalId":55942,"journal":{"name":"Conservar Patrimonio","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66721057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Monitoring volatile pollutants in museum microclimates remains an unusual practice in most institutions. Volatile organic compounds (VOCs) can be released by many sources, including the artefacts’ materials themselves. The presence of pollutants in an enclosed space with poor ventilation, adding to high temperature and relative humidity levels or significant fluctuations, may increase the risk of damage for the more susceptible materials. The tendency observed in museums to enclose artefacts in vitrines or boxes may contribute to the formation of microclimates with high VOCs concentration. Based on the studies developed in the last decades, this work intends to draw attention to the risks associated with gaseous pollutants in museum environment and outline some recommendations that encourage cultural heritage institutions to implement a pollutant monitoring plan associated with risk prevention.","PeriodicalId":55942,"journal":{"name":"Conservar Patrimonio","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2021-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45280747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
