M.Tech. (Fine Art) / The development of contemporary artistic practice, often termed ‘new media’ art, has bought about new challenges in the re-interpretation of conservational data for the curatorial re-presentation of such artworks. These challenges are intensified in artworks of a non-traditional, transient, intangible and / or ephemeral nature. As such, new media works embrace dynamism and fluidity as part of their intangibility and ephemerality. The conservation of such works now requires consideration of the various elements that make up the work, particularly those where the medium predicates meaning. In this study I investigate the institutions and systems which intervene in this conservation of intangible and ephemeral art for future re-presentation and exhibition. I argue that, by compiling notational data (as a work’s ‘score’) of culturally significant ephemeral and intangible artworks the curator is required to refer to the gathered notational data as a reliable guideline for the re-presentation of a work’s ‘true nature’. This raises questions about which parts of an artwork form its true nature and which components are considered variable allowing them to be altered, replaced or migrated. Any re-presentation of the work is therefore dependent on a thorough investigation of the artwork’s essential elements in terms of the artist’s intent, as well as an in-depth contemplation of external / environmental influences. The dynamic (and thus true) nature of specific ephemeral and intangible art objects in the work of Olafur Eliasson, James Webb as well as my own upon, re-presentation, is the focus of this research study.

Para tanto, o estudo tratou da revisão da documentação existente junto ao museu, que até o momento não havia sido sistematizada e organizada. Dado o volume de elementos a serem tratados em conjunto, e com a finalidade de facilitar posteriores acessos à coleção, o acervo ganhou um banco de dados. Este reúne as informações existentes nos diversos tombamentos e nas fichas catalográficas, fornecendo subsídios sobre trocas de acessórios e problemas de conservação, por quê a coleção passou ao longo dos anos, além de contar com registros fotográficos / Abstract: Based on the analyze of the documents about the Neapolitan crib that belongs to Museu de Arte Sacra de São Paulo, the research intended to put together its historical information to allow create policy for its conservation and preservation. To achieve it¿s proposed, during the study, all documents that exist in the museum was reviewed and organized. As lots of records must be treated together, and intending to improve access into the collection, it was designed one database to manage the collection. It puts together the information of the different inventory and cataloguing data, and offers elements of the change of the accessories, conservation problems and photographic records / Mestrado / Historia da Arte / Mestre em História

Indiana University-Purdue University Indianapolis (IUPUI) / Finely-tuned solvent mixtures are used by art conservators for the difficult task of safely and selectively removing yellowed varnish, disfiguring grime, and discolored overpaint from the surface of oil paintings. This process is often referred to as “picture cleaning” and depends on the different solubilities of the obfuscating surface materials and the underlying paint medium. However, differential evaporation rates for the solvents used in these carefully formulated cleaning mixtures can change the potency of the mixture over time, which could potentially lead to solutions having solubility characteristics that are ineffective at cleaning, or worse yet, are deleterious to artists’ oil paints. Azeotropic blends of solvents have been proposed as an alternative for maintaining consistent solvent composition throughout the evaporation process while benefiting from their high vapor pressure relative to the pure solvents. Azeotropes are specific combinations of two or more solvents at a precise concentration that behave as a single solvent, maintaining a constant composition in both the liquid and vapor phases. The use of purportedly azeotropic solvent blends has appeared in the art conservation literature for the cleaning of historic objects and paintings. However, these solvent mixtures are taken from tables of azeotropic compositions given at their boiling point. We have studied one of these solutions, a 19:81 vol% mixture of isopropanol and n-hexane. For the first time, the actual evaporation behavior of this purported azeotropic mixture was followed in detail at room temperature conditions. Through the use of rudimentary vapor pressure measurements, gravimetric analysis, as well as sophisticated compositional determinations of both the liquid phase and headspace of evaporating mixtures by gas chromatography, this particular cleaning solution has been shown to be zeotropic (i.e. NOT an azeotrope) under the conditions typical of conservation studios. The true room temperature azeotropic composition was found instead to contain half as much isopropanol at 9.5 vol%. Art conservators should therefore be dubious of purportedly azeotropic mixtures reported at boiling points well above room temperature. Individual azeotropic cleaning blends are best determined chemically prior to their use in art restoration. Furthermore, the introduction of a model paint film to the evaporating room temperature azeotrope was shown to further confound its behavior, calling into question whether solvent systems can be configured to evaporate with constant composition from the surface of an artwork.

Ce travail doctoral se penche sur un groupe d’artistes et d’artisans actifs dans la seconde moitié du XIXe siècle dans le domaine de la sculpture, et plus précisément sur la façon dont ceux-ci ont à a fois restauré de nombreuses sculptures médiévales et réalisé des sculptures néo-gothiques. Le sujet a été circonscrit à la sculpture religieuse mobilière en bois, et plus spécifiquement aux statues et aux retables conservés dans des églises gothiques. Une approche multidisciplinaire, entre Moyen Âge et XIXe siècle, a été privilégiée. Les artistes et artisans étudiés (Jules Helbig, Adrien Hubert Bressers, les frères Blanchaert, Jean-Baptiste Bethune) posent les bases du style dit « des Écoles Saint-Luc » ou illustrent des travaux de la seconde génération (Léon Bressers). Ils sont membres de la Gilde de Saint-Thomas et de Saint-Luc et revendiquent, sous l’influence de l’architecte anglais A.W.N. Pugin, un lien exclusif avec l’art médiéval dans leurs réalisations. Au sein de la Gilde, l'étude de l'art médiéval et les discussions sur le mobilier religieux à créer se doublent d'une recherche sur les règles liturgiques (au sujet des autels principalement), de manière à retrouver, autant que possible, les formes et usages anciens tout en restant conforme avec les prescriptions en vigueur. Les membres, et en particulier les personnalités étudiées, participent ainsi au renouveau chrétien de la seconde moitié du XIXe siècle.<p>Les sculpteurs-restaurateurs et les peintres-restaurateurs sélectionnés visent avant tout une présentation jugée digne des sculptures médiévales qui passent entre leurs mains. Ils sont, pour ce faire, imperméables à toute notion d’authenticité. Les aspects religieux primant et dans un contexte de forte pilarisation, ils adoptent sur cette question une position monolithique, alors même que la réflexion au sujet de la restauration de la sculpture polychromée se développe, notamment au sein de la Commission royale des Monuments. Dans les traitements de restauration, les Blanchaert, les Bressers et Jules Helbig font preuve d’un vrai souci archéologique mais rarement de réflexion critique sur l’opportunité ou pas de reconstituer des éléments lacunaires, sur le bien fondé de l’adjonction des attributs, ou sur les pratiques de décapage et de repolychromie. Ce travail doctoral démontre par ailleurs que les nouvelles polychromies néo-gothiques, en particulier celles confectionnées par les Bressers, sont souvent le reflet, voire des copies, des anciennes polychromies quand elles étaient bien conservées.<p>Les discussions menées au sein de la Gilde ont eu un impact non négligeable sur la question du démembrement des autels baroques et néo-classiques ainsi que sur la création du nouveau mobilier néo-gothique en Belgique. <p><p>L’étude d’une série de retables néo-gothiques apporte de nouvelles clefs de lecture sur la conception des programmes iconographiques globaux, la répartition des retables dans l'espace ecclésial, la typologie des œuvres, la conception des compositions et le style adopté pour les groupes sculptés. L'influence de Pugin a pu être montrée, notamment dans le caractère très hiérarchisé donné aux œuvres, et cela à tous les niveaux de la représentation.<p>Dans son ensemble, ce travail doctoral offre une contribution significative sur l’historicisme et l’histoire des mentalités. <p> / Doctorat en Histoire, art et archéologie / info:eu-repo/semantics/nonPublished
