O estudo científico das camadas de impregnação, com o recurso à microscopia ótica (MO) de reflexão, com luz polarizada e com radiação ultravioleta (UV), cromatografia gasosa acoplada à espectrometria de massa (GC-MS), micro-espectroscopia de infravermelho com transformada de Fourier (micro-FTIR) e microscopia eletrónica de varrimento acoplada a espectrometria de raios X por dispersão de energia (SEM-EDX), possibilitou a identificação de duas camadas compostas por diversos pigmentos aglutinados em óleo de linhaça e ainda a presença de resina colofónia, cola animal e amido.

The aim of the study was the knowledge of materials, artist's practice and collaboration of artists. Technical analysis illuminates the highlights that the artists follow the rules of St. Luke Guild concerning materials and collaboration of artists. Furthermore historical analyses hightlight the purpose that this kind of paintings had a devotional function.

However, this technique has drawbacks when applied in a country of tropical climate and few resources. It is important, when considering the use of this approach, to be mindful of the conservator’s historical role, which can reveal why this technique was, very likely, the best choice for the conservation of the vast patrimony of canvas paintings in Brazil.

During the 9th and 10th of December topics were discussed related to recent events, such as the tragic fire in the National Museum of Rio de Janeiro, which occurred just over a year earlier; to the challenges posed by the conservation of new media art, contemporary art and scientific collections, as well as to the preservation of so-called more "traditional" cultural assets; without neglecting the necessary joint reflections about training on conservation and restoration on both sides of the Atlantic.

Selon le pays d'origine, le traitement structurel de peintures sur toile varie largement, refletant les conditions climatiques mais egalement les traditions d'enseignement.

The triptych was restored at the beginning of the 20th century and presents a great number of zones with repaints and colour alterations that can be observed on the whole of their surface. The identification of the original pigments and restoration pigments was based on their characteristic colour and the correlation between the detected elements and the named "key elements" of ancient pigments (Ca, Fe, Cu, Hg, Pb,…) and modern pigments (Ti, Ba, Cr, Zn, Co, Cd,…). The analysis of the triptych has been carried out in situ by means of portable instrumentation.
