Enlargements of support are considered historical additions with a huge documentary weight, so making decisions about their conservation entails great responsibility. Furthermore, additions can be key for a painting to fulfil its function within a certain social assemblage or network, so to promote correct decision making, it is vital to know the reasons why a painting was enlarged. The aim of this research has been to develop a classification of enlarged paintings, according to the purpose of the enlargement. The classification includes the following categories: updating pictures, adaptation to a new space and/or a new frame, completing mutilated paintings, changes in iconography, enlargement in order to create independent works, and grouping paintings together.","PeriodicalId":55942,"journal":{"name":"Conservar Patrimonio","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2020-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49302939","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 methodology is based on the selection of case studies of the functional unit of the historical center to assemble simplified models according to the height/width (H/W) ratio and east-west and north-south directions. These models are simulated through the application of computational fluid dynamics (CFD), whose calculation uses values from the wind for the month of greater intensity and according to prevailing speeds and directions. The results show that the geometric relationship affects the change in wind speed and therefore modifies the apparent temperature inside it, which may increase or decrease up to 4 °C depending on the H / W ratio, orientation and time of day.","PeriodicalId":55942,"journal":{"name":"Conservar Patrimonio","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2020-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48051258","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}

While the significance of meteorites as natural heritage is relatively easy to establish, the implication of their meaning as scientific heritage may be more difficult to define. With this aim in mind, in this paper, we present the catalogue standards for meteorite specimens, preserved either in natural history museums or in private collections, proposed by the Italian Istituto Centrale per il Catalogo e la Documentazione–ICCD (Central Institute for Catalogue and Documentation). This work outlines the structure of the catalogue card that describes the meteorite specimen along with other information related to the sample (e.g., archival documentation on collectors and traders, museum catalogues and inventories, general bibliography). This essay concludes discussing the cataloguing, according to ICCD standards, of two Renazzo meteorite specimens, which fell in the eponymous Italian village in 1824 and are now preserved at the Natural History Museum of the University of Firenze.","PeriodicalId":55942,"journal":{"name":"Conservar Patrimonio","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2020-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47467584","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 construction materials of historical effigies differ to the contemporary ones, yet the construction process of the wax parts has more or less remained unchanged over the centuries. This paper starts with the history, construction materials and manufacture techniques of wax effigies. The inseparable relation of the wax effigies and their costumes is explained, and the characteristics and deterioration agents of their most important construction materials are presented in order to understand their needs for preservation, with emphasis on wax and fabrics. The aim of this paper is to suggest preventive conservation guidelines for wax effigies, with proposals for appropriate environmental conditions during display and storage, and suggestions for proper handling, storage and transportation. Advice for disaster preparedness and actions in cases of emergency situations is also provided.","PeriodicalId":55942,"journal":{"name":"Conservar Patrimonio","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2020-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48188197","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}

Throughout the ages, different preventive and curative conservation measures were adopted to manage biodeterioration in Portuguese institutions, but the problem persists. A historic review of different methodologies used to prevent biodeterioration in the Portuguese context is presented and compared to international trends. It focuses on theories and practices of paper conservation on par with their evolution and a comparison between the art collectors' world and Libraries and Archives is also made. Biodeterioration management has always been a major concern, namely amid librarians and archivists, among the first ones to endorse the implementation of preservation policies. Although preservation awareness has a relatively long history, it is vital to encourage a better understanding of it at the decision-making level. In fact, the implementation of preventive conservation strategies continues to be unsatisfactory, despite the current sustainability issues and the dangers of handling contaminated documentation.","PeriodicalId":55942,"journal":{"name":"Conservar Patrimonio","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2020-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43734035","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}

{"title":"Chromatic changes in paintings of Adriano de Sousa Lopes after the removal of aged varnish","authors":"J. Linhares, L. Cardeira, Ana Bailão, Ruben C. Pastilha, S. Nascimento","doi":"10.14568/cp2018064","DOIUrl":"https://doi.org/10.14568/cp2018064","url":null,"abstract":"The ability to digitally remove the varnish layer during the pre-conservation diagnostic of a painting, without any chemical or physical intervention, could be an advantage because it enables the prediction of the outcome of the cleaning procedure of the protective layer and contributes to the treatment proposal. Two paintings from Adriano de Sousa Lopes were investigated by hyperspectral imaging in the visible range, before and after the varnish layer removal. The spectral ref lectance was estimated in each case and its comparison used to assess the effect of the varnish layer removal. The simulated paintings with the old varnish layer were compared with those restored, with no varnish, by comparing the chromaticity coordinates and other chromatic descriptors. It was found that considering the effect of the varnish layer of each painting individually produces lower errors than considering the average of the varnish layer across paintings. It was also found that simulating the varnish layer removal without knowing the varnish transmittance produces limited results and that the errors are smaller if the chromatic content is assessed without considering lightness. Resumo A capacidade de remover digitalmente a camada de verniz na fase de diagnóstico de uma pintura, sem qualquer intervenção química ou física, poderá ser uma vantagem, pois permite prever o resultado do procedimento de limpeza da camada de proteção e auxiliar a proposta de tratamento. Duas pinturas de Adriano de Sousa Lopes foram investigadas por imagiografia hiperespectral na zona da luz visível, antes e após a remoção da camada de verniz. A ref lectância espectral foi estimada em cada caso e sua comparação utilizada para avaliar o efeito da remoção da camada de verniz. As pinturas simuladas com a camada de verniz envelhecida foram comparadas com a intervencionada, sem verniz, comparando as coordenadas cromáticas e outros descritores cromáticos. Verificou-se que considerando o efeito da camada de verniz de cada pintura individualmente obtêm-se erros mais baixos do que considerando a média da camada de verniz das duas pinturas. Verificou-se também que simular a remoção da camada de verniz sem saber a transmitância do verniz original produz resultados limitados e que os erros são menores se o conteúdo cromático for obtido sem considerar a luminosidade.","PeriodicalId":55942,"journal":{"name":"Conservar Patrimonio","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2020-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45134988","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 is a work of great importance in the establishment of the conquest of Goa by the Portuguese but also for understanding the influence of Portuguese painting overseas. Goa Cathedral former altarpiece is revealed as a crucial study source of Garcia Fernandes' creative process. There is evidence in the vigorous underdrawing of these paintings, of the existence of different types of drawing, as well as abandoned iconographic themes, or formal alterations of compositions. The iconographic and stylistic study evidences north and south-European influences in the choice and representation of the themes around the Martirio de Santa Catarina. In the present study, this work is compared in the making of the underdrawing with other works attributed to Garcia Fernandes.","PeriodicalId":55942,"journal":{"name":"Conservar Patrimonio","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2020-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43930365","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 was strictly made according to a pattern and was constructed in a box shape from leather and canvas, painted black on the exterior. An example of this model, which belongs to the Lisbon Military Museum collection (MML02048), was removed from the storage in 2016 in order to be inventoried. It was subsequently restored within the curricular unit “conservation and restoration project” of the Conservation and Restoration Bachelor so it could be placed on permanent exhibition. This object was likely used in campaign in Mozambique in 1894-95 by the bugler Antonio Moura, taking part on the combat of Marracuene. Areas of deterioration, such as f laking paint and canvas losses, were caused mainly by storage conditions and improper care over the course of more than a century. The treatment was guided towards its ideal state, enhancing mostly historical and aesthetical values which were obtained through investigation.  \u0000  \u0000Received: 2018-12-9Revised: 2019-9-6Accepted: 2020-5-28Online: 2020-7-31Publication: 2020-7-31","PeriodicalId":55942,"journal":{"name":"Conservar Patrimonio","volume":null,"pages":null},"PeriodicalIF":0.3,"publicationDate":"2020-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48148821","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}
