Cor e conservação: as intervenções cromáticas no Terreiro do Paço

Foi há poucos dias disponibilizada online a seguinte tese de mestrado:

Daniela Álvaro Chagas, Cor e Conservação. As Intervenções Cromáticas no Terreiro do Paço, Lisboa, Universidade Técnica de Lisboa, Faculdade de Arquitectura, 2010.

Está livremente disponível aqui.

Resumo:

O Terreiro do Paço constitui uma obra importantíssima para a cidade de Lisboa e para Portugal, tanto por este lugar ter sido um palco privilegiado da História Portuguesa como pelo valor arquitectónico que o conjunto edificado possui. Sendo um dos elementos mais significativos do Património Português a sua salvaguarda é essencial. A cor, por estar presente em tudo e ser fundamental para a percepção da realidade, destaca-se como um elemento muito importante para a Arquitectura na medida em que contribui para a definição da sua imagem. A presente Dissertação tem como principal objectivo analisar as intervenções cromáticas que o conjunto edificado do Terreiro do Paço possuiu ao longo do tempo, avaliando-se o impacto de cada uma delas face à arquitectura do conjunto e à envolvente. Em função das análises e estudos desenvolvidos, pretende-se então definir uma adequada e fundamentada proposta cromática. O trabalho desenvolvido estrutura-se segundo três capítulos: Cor, Cultura e Arquitectura, Cor e Conservação e Caso de Estudo. No primeiro capítulo aborda-se a Cor como disciplina, estudando-se as relações existentes entre cor e homem, cultura e lugar, arquitectura e cidade. No segundo, analisa-se a Cor na arquitectura e na cidade enquanto patrimónios, apresentando-se estudos cromáticos em centros históricos europeus, abordando-se alguns casos de cor na arquitectura portuguesa e estudando-se ocaso da cor de Lisboa. No terceiro apresenta-se o caso de estudo: as intervenções cromáticas no Terreiro do Paço; desenvolvendo-se uma análise cronológica e um estudo projectual sobre a cor no conjunto edificado, definindo-se assim a proposta cromática. A principal conclusão prende-se com a importância que a Cor tem para a Arquitectura, percebendo-se que no âmbito da Arquitectura Histórica e Patrimonial as questões cromáticas são fundamentais. Por isso, para salvaguardar a identidade e autenticidade do Terreiro do Paço é indispensável que a Cor original seja também preservada.

Espectroscopia de infravermelho longínquo de reflectância total atenuada aplicada ao estudo do património cultural

A seguinte tese de doutoramento está disponível com acesso livre aqui:

Elsebeth Langholz Kendix, Trasmission and Reflection (ATR) Far-Infrared Spectroscopy Applied in the Analysis of Cultural Heritage Materials, Bollogna, Allma Matter Sttudiiorum, Uniiversiittà dii Bollogna, 2009.

Resumo:

FIR spectroscopy is an alternative way of collecting spectra of many inorganic pigments and corrosion products found on art objects, which is not normally observed in the MIR region. Most FIR spectra are traditionally collected in transmission mode but as a real novelty it is now also possible to record FIR spectra in ATR (Attenuated Total Reflectance) mode. In FIR transmission we employ polyethylene (PE) for preparation of pellets by embedding the sample in PE. Unfortunately, the preparation requires heating of the PE in order to produces at transparent pellet. This will affect compounds with low melting points, especially those with structurally incorporated water. Another option in FIR transmission is the use of thin films. We test the use of polyethylene thin film (PETF), both commercial and laboratory-made PETF. ATR collection of samples is possible in both the MIR and FIR region on solid, powdery or liquid samples. Changing from the MIR to the FIR region is easy as it simply requires the change of detector and beamsplitter (which can be performed within a few minutes). No preparation of the sample is necessary, which is a huge advantage over the PE transmission method. The most obvious difference, when comparing transmission with ATR, is the distortion of band shape (which appears asymmetrical in the lower wavenumber region) and intensity differences. However, the biggest difference can be the shift of strong absorbing bands moving to lower wavenumbers in ATR mode. The sometimes huge band shift necessitates the collection of standard library spectra in both FIR transmission and ATR modes, provided these two methods of collecting are to be employed for analyses of unknown samples. Standard samples of 150 pigment and corrosion compounds are thus collected in both FIR transmission and ATR mode in order to build up a digital library of spectra for comparison with unknown samples. XRD, XRF and Raman spectroscopy assists us in confirming the purity or impurity of our standard samples. 24 didactic test tables, with known pigment and binder painted on the surface of a limestone tablet, are used for testing the established library and different ways of collecting in ATR and transmission mode. In ATR, micro samples are scratched from the surface and examined in both the MIR and FIR region. Additionally, direct surface contact of the didactic tablets with the ATR crystal are tested together with water enhanced surface contact. In FIR transmission we compare the powder from our test tablet on the laboratory PETF and embedded in PE. We also compare the PE pellets collected using a 4x beam condenser, focusing the IR beam area from 8 mm to 2 mm. A few samples collected from a mural painting in a Nepalese temple, corrosion products collected from archaeological Chinese bronze objects and samples from a mural paintings in an Italian abbey, are examined by ATR or transmission spectroscopy.

Estudo através de métodos de espectroscopia de problemas de conservação de pinturas modernas e contemporâneas

Acabou de ser colocada online com acesso livre a seguinte tese de mestrado:

Joana Andreia Lameiras Domingues, Spectroscopy Studies on Conservation Issues in Modern and Contemporary Paintings, Lisboa, Faculdade de Ciências e Tecnologia da Universidade Nova de Lisboa, 2010.

Está aqui.

Resumo:

Modern and contemporary paintings are one of today’s grand challenges in conservation of cultural heritage. Particularly, these paintings have often been retouched using materials rather similar to originals, thus, compromising the reversibility of the overpainting. In this work, FTIR and Raman spectroscopies, assisted by optical microscopy, were used to evaluate the effectiveness and harmfulness of chemical and laser cleaning methods for the removal of overpaints. Representative mock-ups prepared with commercial paint formulations were used. The laser cleaning experiment was part of an interdisciplinary study which aims the evaluation of method’s limitations by using the most aggressive cleaning parameters. The combined use of FTIR and Raman spectroscopies could identify constituent materials of modern paints, controlling their behaviour under cleaning, while optical microscopy allowed the evaluation on surface morphology. In addition, equivalent portable equipments from MOLAB were covered as a preparation for in situ analysis. Several problems in the selective removal of overpaints were found with chemical cleaning. The laser cleaning showed better efficiency in removing them, although, some alterations occurred upon laser irradiation, for instance, binder degradation with carbon formation and titanium white alteration. The proposed spectroscopic protocol was considered useful for controlling different cleaning methods in modern and contemporary paintings.

Aplicação da microscopia de infravermelho ao estudo do património cultural

A seguinte tese de doutoramento está livremente disponível aqui:

Edith Michelle Maryse Joseph, Application of FTIR Microscopy to Cultural Heritage Materials, Bollogna, Allma Matter Sttudiiorum, Uniiversiittà dii Bollogna, 2009.

Resumo:

Research in art conservation has been developed from the early 1950s, giving a significant contribution to the conservation-restoration of cultural heritage artefacts. In fact, only through a profound knowledge about the nature and conditions of constituent materials, suitable decisions on the conservation and restoration measures can thus be adopted and preservation practices enhanced. The study of ancient artworks is particularly challenging as they can be considered as heterogeneous and multilayered systems where numerous interactions between the different components as well as degradation and ageing phenomena take place. However, difficulties to physically separate the different layers due to their thickness (1-200 µm) can result in the inaccurate attribution of the identified compounds to a specific layer. Therefore, details can only be analysed when the sample preparation method leaves the layer structure intact, as for example the preparation of embedding cross sections in synthetic resins. Hence, spatially resolved analytical techniques are required not only to exactly characterize the nature of the compounds but also to obtain precise chemical and physical information about ongoing changes. This thesis focuses on the application of FTIR microspectroscopic techniques for cultural heritage materials. The first section is aimed at introducing the use of FTIR microscopy in conservation science with a particular attention to the sampling criteria and sample preparation methods. The second section is aimed at evaluating and validating the use of different FTIR microscopic analytical methods applied to the study of different art conservation issues which may be encountered dealing with cultural heritage artefacts: the characterisation of the artistic execution technique (chapter II-1), the studies on degradation phenomena (chapter II-2) and finally the evaluation of protective treatments (chapter II-3). The third and last section is divided into three chapters which underline recent developments in FTIR spectroscopy for the characterisation of paint cross sections and in particular thin organic layers: a newly developed preparation method with embedding systems in infrared transparent salts (chapter III-1), the new opportunities offered by macro-ATR imaging spectroscopy (chapter III-2) and the possibilities achieved with the different FTIR microspectroscopic techniques nowadays available (chapter III-3). In chapter II-1, FTIR microspectroscopy as molecular analysis, is presented in an integrated approach with other analytical techniques. The proposed sequence is optimized in function of the limited quantity of sample available and this methodology permits to identify the painting materials and characterise the adopted execution technique and state of conservation. Chapter II-2 describes the characterisation of the degradation products with FTIR microscopy since the investigation on the ageing processes encountered in old artefacts represents one of the most important issues in conservation research. Metal carboxylates resulting from the interaction between pigments and binding media are characterized using synthesised metal palmitates and their production is detected on copper-, zinc-, manganese- and lead- (associated with lead carbonate) based pigments dispersed either in oil or egg tempera. Moreover, significant effects seem to be obtained with iron and cobalt (acceleration of the triglycerides hydrolysis). For the first time on sienna and umber paints, manganese carboxylates are also observed. Finally in chapter II-3, FTIR microscopy is combined with further elemental analyses to characterise and estimate the performances and stability of newly developed treatments, which should better fit conservation-restoration problems. In the second part, in chapter III-1, an innovative embedding system in potassium bromide is reported focusing on the characterisation and localisation of organic substances in cross sections. Not only the identification but also the distribution of proteinaceous, lipidic or resinaceous materials, are evidenced directly on different paint cross sections, especially in thin layers of the order of 10 µm. Chapter III-2 describes the use of a conventional diamond ATR accessory coupled with a focal plane array to obtain chemical images of multi-layered paint cross sections. A rapid and simple identification of the different compounds is achieved without the use of any infrared microscope objectives. Finally, the latest FTIR techniques available are highlighted in chapter III-3 in a comparative study for the characterisation of paint cross sections. Results in terms of spatial resolution, data quality and chemical information obtained are presented and in particular, a new FTIR microscope equipped with a linear array detector, which permits reducing the spatial resolution limit to approximately 5 µm, provides very promising results and may represent a good alternative to either mapping or imaging systems.

A descoberta dos raios X e a sua influência na arte do início do século XX

Acabou de ser disponibilizada na internet a seguinte tese de doutoramento:

Está aqui.

Resumo:

El presente trabajo se ocupa de la contribución de los rayos-x a la reconfiguración epistemológica y plástica de la realidad en el primer tercio del siglo XX. Desde el último cuarto del siglo XIX la realidad estaba siendo redefinida en términos de relaciones de fuerzas y se comenzaba a poner en cuestión la intemporalidad del conocimiento. En ese contexto, los rayos-x y su huella radiográfica contribuyeron al descrédito del paradigma de realidad positivista y ofrecieron a los artistas un modelo analógico de visión y de presentación de la realidad; esto es, un modelo tanto procesual como formal con el que ver y dar a ver sus visiones. Los rayos-x y la radiografía desplegaron el horizonte de visión de científicos, filósofos y artistas en un momento, 1895, en el cual el cinematógrafo, el psicoanálisis y, en poco tiempo, la aviación, comenzaron a revolucionar los modos de ver y de pensar la realidad, la visión y el conocimiento mismos. Se ha trabajado en torno a dos momentos esenciales: el del descubrimiento de los rayos-x y el de los ecos en pintura y en literatura que comenzó a tener una década más tarde. La bibliografía empleada gira en torno a los mismos núcleos.

Sophia Lahlil, Redécouverte des Procédés d'Opacification des Verres à l'Antimoine à Travers l'Histoire. Étude des Antimoniates de Calcium, Paris, Université Pierre et Marie Curie, 2008.

Resumo :

L'objectif de ce travail de recherche est de retrouver les modes de fabrication des verres opacifiés aux antimoniates à travers l'Histoire depuis l'origine jusqu'à aujourd'hui par une approche conjointe de l'archéométrie et des sciences des matériaux. Pour ce faire, nous avons réalisé des synthèses de verres opaques en laboratoire et étudié des productions de verres opacifiés aux antimoniates de calcium allant de l'Antiquité à nos jours. En comparant les caractéristiques physico-chimiques de verres de référence synthétiques ou contemporains, dont le mode de fabrication est connu, avec celles d'échantillons de verres opaques anciens ou modernes, dont le mode de fabrication est inconnu, nous avons pu déterminer des critères permettant d'identifier les procédés d'opacification des trois productions de verre étudiées : - les verres décorés de la XVIIIème dynastie égyptienne (1570-1292 av. J.C.), - les tesselles de mosaïque romaines d'Aquilée et de Rome, datant du 1er s. av. au 4ème s. apr. J.C., - les verres filés dits « de Nevers » datant du 18ème s. apr. J.C..
