Carmen Miranda, cantante e intérprete brasileña, después de una carrera discográfica de gran éxito en las pantallas de su país natal, se convirtió en estrella de Broadway y Hollywood entre 1930 y 1950. Su manera de vestir fue una interpretación del traje tradicional baiana, utilizado por los vendedores ambulantes en el estado brasileño de Bahía. Su aspecto en el vestir ha marcado un estilo en la moda femenina, desde su llegada a los Estados Unidos en 1939 hasta la actualidad. La colección tanto de sus trajes como de accesorios se encuentra reunida en el Museo Carmen Miranda (Rio de Janeiro, Brasil), esta representa la historia de Carmen Miranda, y la riqueza de la confección de sus trajes y los distintos materiales empleados en su elaboración. Estos materiales son un reto desde el punto de vista de la conservación-restauración de textiles contemporáneos. Son objetos compuestos de distintos materiales que están en constante interacción entre sí, haciendo que la intervención de conservación sea un desafío. Con la finalidad de conocer la gama de materias primas empleadas en una de las piezas más importantes de la Colección Carmen Miranda, el turbante de frutas (número de inventario 374), se presentan en este trabajo de investigación los resultados obtenidos en la caracterización físico-química mediante, microscopio óptico con luz polarizada, microscopio electrónico de barrido con microanálisis por dispersión de energías de rayos X (SEM-EDX) y espectroscopia infrarroja por transformada de Fourier con dispositivo de reflectancia total atenuada (FTIR-ATR), de los elementos ornamentales (una selección de lentejuelas) del turbante de frutas. Los materiales identificados han sido compuestos tipo proteína (probablemente, gelatina), nitrato de celulosa y acetato de celulosa; además, las alteraciones de cada uno de ellos responden a tres tipologías diferentes de craqueladuras.

“…Nitration is a reversible process, so over time, hydrolysis causes the emission of nitrogen oxides (NO x ) (denitration) and reversion of CN to cellulose. In a museum environment this means that with ageing, objects release acid volatile organic compounds, which, not only render them inherently unstable, but endanger other materials in their proximity too [5][6][7]. This acid release both occurs through and induces chain scission, resulting in molecular weight loss [4,7].…”

This article describes the development of a suitable Gel Permeation Chromatography method for cellulose nitrate plasticised with camphor (celluloid) found in cultural heritage. Current sample preparation and dissolution methods, apart from focusing on native, nonderivatised cellulose, require long preparation times, and often employ solvents that induce degradation. This study aims to develop a systematic method for sample preparation of cellulose nitrate that uses the least sample amount possible, is nondegrading, and can be applied on differently aged samples. This is investigated through identification of a suitable solvent system and a statistically designed experiment testing the critical variables affecting the analysis, namely sample condition, sample, and salt concentration (lithium chloride) in N,N-dimethylacetamide. The use of 0.1% sample was inadequate for analysis because it did not fully dissolve in any salt concentration, while the 0.3% negatively impacted the analysis with its high molecular weight distributions. The 0.2% cellulose nitrate in a solution of 0.5% lithium chloride in N,N-dimethylacetamide offered the most consistent and repeatable molecular weight data. This method miniaturised the sample as much as possible and is suitable for museum objects in various ageing conditions.

Analytical characterization of polymers used in conservation and restoration by ATR-FTIR spectroscopy

et al. 2009

In the last few decades many new polymers have been synthesized that are now being used in cultural heritage conservation. The physical and chemical properties and the long-term behaviors of these new polymers are determined by the chemical composition of the starting materials used in their synthesis along with the nature of the substances added to facilitate their production. The practical applications of these polymers depend on their composition and form (foam, film, sheets, pressure-sensitive adhesives, heat-seal adhesives, etc.). Some materials are used in restoration works and others for the exhibition, storage and transport of works of art. In all cases, it is absolutely necessary to know their compositions. Furthermore, many different materials that are manufactured for other objectives are also used for conservation and restoration. The technical information about the materials provided by the manufacturer is usually incomplete, so it is necessary to analytically characterize such materials. FTIR spectrometry is widely used for polymer identification, and, more recently, ATR-FTIR has been shown to give excellent results. This paper reports the ATR-FTIR analysis of samples of polymeric materials used in the conservation of artworks. These samples were examined directly in the solid material without sample preparation.
