Resumo(s)
The present dissertation, entitled Conservation and Restoration in the Triptych in Blue Painting, by Eugen Hersch (1887-1967), arises in the context of the Masters in Conservation Sciences, Restoration and Contemporary Art Production. The dissertation has as general objectives the technical and material study of the work and the realization of a conservation and restoration intervention. The opportunity to intervene arose in the summer of 2021, in situ, due to the risk of detachment of the pictorial layer of the central painting of the triptych, the colour changes caused by previous treatments, and the yellowing of the protective layer of the metallic foil. The painting entitled Triptych in Blue consists of three paintings and three predellas, all with representations of human figures. It presents a mixed technique on canvas and plywood, with maximum dimensions of 4 m high, 6 m long and 0,06 m thick. It is privately owned, acquired in 2009, and underwent another intervention between 2012 and 2013. The study focuses on the particularities of the work. Among the specific objectives were: to create a management system for acquired information based on geographic information technologies; understand the relationship between the techniques of mural painting and on canvas applied by Hersch in this triptych; look for solutions to fill gaps, namely in the chromatic reintegration process, and ways to evaluate and validate the result. To fulfil the objectives, different research tools were implemented: bibliographic research; interviews with professionals in conservation and restoration; technical and material study, through examination and analysis techniques; making models that allowed understanding the artist's technique and testing different filling materials for the intervention; and, finally, documentation techniques with photogrammetry were used to acquire digital surface models, produce orthophotographs and use a geographic information system for mapping and spatial characterization of the pictorial surface
