Resumo: Testimony of historical restoration practices, an 18th century painting, “O Cavaleiro da Or dem de Malta”, was subjected in the past to the application of oil based coating impregnations, on the reverse of the canvas support. The study of the impregnation materials was carried out using optical microscopy (OM) under visible reflected and polarized light and under ultraviolet light (UV), gas chromatography – mass spectrometry (GC-MS), Fourier transform infrared spectroscopy, and scanning electron microscopy – energy dispersive X-ray spectrometry (SEM-EDX), allowing the identification of two paint layers composed of several pigments and linseed oil as binding material and also the detection of colophony resin, an animal glue and starch.

El estúdio científico de las capas de impregnación, mediante microscopia óptica reflectida (MO) con luz polarizada y con radiación ultravioleta (UV), cromatografía de gases con espectrometria de masa (GC-MS), micro‑espectroscopía de infrarrojos por transformada de Fourier (micro‑FTIR) y microscopía electrónica de barrido con espectrometría de energía dispersiva de rayos X (SEM‑EDS), permitió la idenficación de dos capas compuestas por varios pigmentos mezclados en aceite de linaza, y también detectar la presencia de resina de colofonia, cola animal y almidón.Testemunho de intervenções históricas de restauro, o suporte da pintura sobre tela “O Ca valeiro da Ordem de Malta”, datada do século XVIII, foi alvo da aplicação, pelo seu reverso, de camadas de impregnação à base de óleo e pigmentos. O estudo científico das camadas de impregnação, com o recurso à microscopia ótica (MO) de reflexão, com luz polarizada e com radiação ultravioleta (UV), cromatografia gasosa acoplada à espectrometria de massa (GC-MS), micro-espectroscopia de infravermelho com transformada de Fourier (micro-FTIR) e microscopia eletrónica de varrimento acoplada a espectrometria de raios X por dispersão de energia (SEM-EDX), possibilitou a identificação de duas camadas compostas por diversos pigmentos aglutinados em óleo de linhaça e ainda a presença de resina colofónia, cola animal e amido.Universidade Católica Portuguesa2016-01-01T00:00:00Zjournal articleinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://doi.org/10.34618/ecr.8.14227oai:ojs.revistas.ucp.pt:article/7933Estudos de Conservação e Restauro; No 8 (2016); 71-81Estudos de Conservação e Restauro; n. 8 (2016); 71-811647-209810.34618/ecr.8.14237reponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPporhttps://revistas.ucp.pt/index.php/ecr/article/view/7933https://doi.org/10.34618/ecr.8.14227https://revistas.ucp.pt/index.php/ecr/article/view/7933/8088Copyright (c) 2016 Andréa Teixeira, Ana Calvo, Maria Aguiarhttp://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessTeixeira, AndréaCalvo, AnaAguiar, Maria2022-09-22T10:29:13Zoai:ojs.revistas.ucp.pt:article/7933Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T15:57:16.535Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
