Caracterização dos pigmentos da Berlinda de Aparato do Imperador D. Pedro II usando técnicas analíticas não destrutivas

Abstract

The Imperial Horse-drawn carriage Emperor D. Pedro II is a museological object with very important historical implications for Brazilian culture, as it is not only related to the image of Emperor D. Pedro II, but with the entire Second Reign, constituting a real symbol of imperial power. The berlin device, also known as D. Pedro II Gala Carriage, was specially commissioned for the coronation ceremony of D. Pedro II, in 1841 and belongs to the collection of the Imperial Museum, located in the city of Petrópolis, Rio de Janeiro, Brazil. In this work, the original pigments applied to all the decorative panels were analyzed using non-destructive analytical techniques. Altogether, seven colors (green, red, yellow, blue, black, brown, white) and gilding were characterized by UV light fluorescence, X-Ray Fluorescence (XRF), Micro X-Ray Fluorescence (μXRF), Macro X-Ray Fluorescence Scanning (MA-XRF), Scanning Electron Microscopy with Energy Dispersive X-Ray Spectroscopy (SEM-EDS) and Raman spectroscopy. The XRF and MA-XRF measurements were performed in situ using portable equipment and the other techniques were performed on samples provided by the Restoration and Conservation team of the Imperial Museum. According to the key elements detected, the original pigments suggested as the color palette used by the painter of D. Pedro II's berlin are Verdigris, Green Earth, Vermilion, Naples yellow, Chrome Yellow, Ocher pigments, Lead white, Cobalt and gold leaf. The results found are in agreement with those described in the literature.
