In-situ survey of the presence of soluble salts associated with decaying azulejos
Esteves, L.; Mirão, J.; Dias, L.; Candeias, A.; Mimoso, J.Pattern or figurative azulejos are commonly found decorating the interior of churches, palaces and religious buildings in Portugal, representing local productions from the late 16th century onwards. The history and micro-climatic background of each building determined that not every azulejo reached the present day in good condition. Restorers tend to associate azulejo decay to the action of soluble salts throug...
Experimental research with salt crystallization in historic Portuguese azulejos
Esteves, L.; Candeias, A.; Mimoso, J.For five centuries, azulejos have been widely used in Portugal as decorative architectural linings. The most serious form of degradation is the spall of the glaze containing the decoration. Crystallisation of soluble salts is often pointed as its main cause, but that remains yet to be proven. Indeed, there are publications on many simulations of salt decay in porous materials such as stone or brick. However, az...
18th century Portuguese tiles: characterization and reproduction study of Ca-ri...
Morais Pereira, S.; Musacchi, J.; Mendes, M.; Leal, A.; Esteves, L.; Santos Silva, A.; Mimoso, J.Majolica tiles from the 17th-18th centuries make up one of the most important art heritages of Portugal. Their characterization and gains in knowledge through their reproduction are important to obtain information about their production methods, raw materials used, origin attribution and to contribute to studies in conservation and development of treatments. A group of Lisbon tiles from the late 17th to 18th ce...
Restoration of semi-industrial glazed ceramic tiles by re-firing
Chaban, A.; Morais Pereira, S.; Esteves, L.; Peddis, F.; Mimoso, J.Semi-industrial glazed ceramic tiles lining urban façades represent a rich heritage asset of Portuguese cities and in particular of Lisbon. However, still a sizeable part of them is being continuously lost. Whenever the façade tiles are decayed, they are usually merely removed and replaced by newly manufactured ones. Following preliminary tests done at LNEC in 2012, we introduce in this communication re-firing ...
Adhesives for outdoor architectural historic azulejo conservation
Morais Pereira, S.; Musacchi, J.; Esteves, L.; Pereira, J.; Cabral-Fonseca, S.; Silva, H. M.; Rodrigues, M. P.; Mimoso, J.Historic ceramic tiles – azulejos – are an important part of the cultural heritage of Portugal. However, there are not many studies about the materials used in their conservation to direct the conservator’s choice. This work is, to our knowledge, the first comprehensive study on the adhesives used to bind fragments of architectural tiles. Attention is paid to the extreme conditions that may challenge the tiles ...
An unlikely catalogue of the production of azulejos by Fabrica Roseira of Lisbo...
Mimoso, J.; Pais, A.; Campelo, J.; Esteves, L.In the second half of the nineteenth century the Roseira factory in Lisbon was one of the most important manufacturers of façade tiles used both in Portugal and in Brazil. “Casa das Bolas”, a condominium building in Lisbon informally named after the glazed tiles decorated with spherical elements in trompe l'oeil of its ground-floor façade, was owned by a member of the Roseira family who erected it using parts o...
Ouro sobre o azul(ejo)
Pais, A.; Mimoso, J.; Lima, C.; Esteves, L.In documents from the 16th and 17th centuries we can read sometimes the expression “golden azulejos”. This is a matter that azulejo historians never fully studied but which raises interesting questions. Sometimes this expression could be related to azulejos in the “lusterware” technique, a secretive and complex process which allowed the ceramic surfaces to be decorated with gold and copper metallic shine. Anoth...
Portuguese Azulejos, World Heritage
Matos, M.; Mimoso, J.; Pais, A.; Esteves, L.; Menezes, M.Few forms of artistic expression capture the nature and the way of life of the Portuguese as the azulejo does. Manufactured and used in other countries, sometimes with superior technical quality, some aspects, however, impart to the way it was and still is used in Portugal an unparalleled originality since the first batches, imported from Andalusia in the late fifteenth century, to the present day when it is us...
Graça Church revisited
Pais, A.; Mimoso, J.; Dumortier, C.; Esteves, L.; Silva, M.; Morais Pereira, S.The important set of azulejos that can be seen today in the ante-sacristy of the Graça Church, in Lisbon, dated from between circa 1565 (year when the building of the new complex was finished) and 1580, is probably one of the most relevant indications of a local production of azulejos in the faience technique during the 2nd half of the 16th century. In the course of a research conducted to determine the origin ...
A abordagem estilística no restauro de azulejos
Esteves, L.; Mimoso, J.Iremos explicitar nesta comunicação as abordagens ao restauro seguidas no Museu Nacional do Azulejo de Portugal (MNAz) através de três exemplos, um que releva a reintegração da imagem, por se considerar haver suficientes elementos orientadores, outro que reconhece a falta de informação e recusa a reabertura do processo criativo, e, finalmente, o tratamento de um caso em que a unidade potencial foi considerada p...
