A presente dissertação incide sobre o estudo de dois conjuntos azulejares pertencentes
ao Museu Nacional do Azulejo (MNAz): um conjunto fragmentado de 20 painéis
rocaille do
século XVIII, e um painel de azulejos com cena mitológica de datação desconhecida.
No âmbito do projeto FCT ChromAz ("O Percurso Cromático do Azulejo Português" -
PTDC/HAR-HIS/1899/2020), do qual integro a equipa e o MNAz é parceiro, os painéis foram
caracterizados química e morfologicamente por μ-EDXRF, SEM-EDS e Colorimetria com o in-
tuito de aprofundar o estudo da cor e contribuir para o esclarecimento de questões relaciona-
das com a proveniência e datação dos painéis. Perante a hipótese de se tratar de uma produ-
ção da Fábrica do Juncal, o conjunto
rocaille foi ainda comparado com um painel proveniente
da mesma. Em simultâneo, foi realizada a intervenção de conservação e restauro de um painel,
seguindo os critérios enquadrados na metodologia e filosofia de intervenção do MNAz. Esta
incluiu a identificação, montagem preliminar e registo fotográfico de cada painel do conjuntorocaille, seguida do diagnóstico e restauro de um deles. Durante a fase de avaliação do estado
de conservação do painel, verificou-se que o principal problema consistia nas lacunas de frag-
mentos e azulejos inteiros, perturbando assim a leitura e respetiva interpretação da obra por
parte do observador. Deste modo, foram apresentadas diferentes propostas de restauro na
reintegração cromática da área de lacuna figurativa com o intuito de melhorar a compreensão
do painel em estudo. A opção selecionada, incidiu sobre uma das propostas de acordo com
os critérios de intervenção do MNAz, tendo sido realizados restauros a frio e a quente.
Os resultados das análises realizadas por μ-EDXRF enquadram-se no esperado para o
século XVIII, tendo-se destacado o castanho claro, sobre o amarelo, que se trata de uma mis-
tura de amarelo de Nápoles com manganês e, tanto quanto se sabe pelo levantamento bibli-
ográfico realizado, não está identificada na literatura para obtenção do castanho. Relativa-
mente às análises realizadas aos pigmentos e vidrado do painel mitológico, este não apresenta
ainda nenhum resultado que permita uma datação segura, enquadrando-se entre o esperado
para os séculos XVII e XVIII, porém são resultados preliminares e o estudo está a decorrer no
âmbito do projeto; o painel do Juncal apresenta algumas diferenças ao nível da cor, mas ainda
que estas diferenças não sejam significativas para descartar a hipótese de uma proveniência
comum, observa-se que a chacota é diferente nos dois casos.
The present dissertation focuses on the study of two tile sets belonging to the National Azulejo Museum (MNAz): a fragmented set of 20 rocaille panels from the 18th century, and a tile panel with a mythological scene of unknown date. In the context of the project FCT ChromAz ("The Chromatic Path of the Portuguese Tile" - PTDC/HAR-HIS/1899/2020), of which I am part of the team and the MNAz is a partner, the panels were chemically and morphologically characterized by μ-EDXRF, SEM-EDS and Color- imetry in order to deepen the study of color and to contribute to the clarification of questions related to the provenance and dating of the panels. Considering the hypothesis that the panels were produced by Fábrica do Juncal, the rocaille set was also compared with a panel from the same factory. Simultaneously, the conservation and restoration intervention of one panel was carried out, following the criteria framed in the methodology and philosophy of intervention of the MNAz. This included the identification, preliminary assembly, and photographic record- ing of each panel of the rocaille set, followed by the diagnosis and restoration of one of them. During the evaluation phase of the conservation status of the panel, it was found that the main problem consisted of gaps in fragments and whole tiles, thus disturbing the reading and inter- pretation of the work by the observer. Thus, different restoration proposals were presented for the chromatic reintegration of the figurative gap area in order to improve the understanding of the panel under study. The selected option, focused on one of the proposals according to the intervention criteria of the MNAz, having carried out cold and hot restorations. The results of the analyses carried out by μ-EDXRF are within the expected range for the XVIII century, with a light brown color having stood out over the yellow, which is a mixture of Naples yellow with manganese and, as far as we know from the bibliographical survey carried out, is not identified in the literature for obtaining brown. Relatively to the analysis of the pig- ments and glaze of the mythological panel, this does not present yet any result that allows a secure dating, fitting between the expected for the XVII and XVIII centuries, but these are pre- liminary results and the study is taking place within the project; the Juncal panel presents some differences in color, but even if these differences are not significant enough to rule out the hypothesis of a common provenance, it is observed that the staining is different in both cases.
