Interdisciplinary Studies of the “Vista Do Desterro” Painting: Historical Approach, Analysis of Materials and Preservation/Restoration Techniques (original) (raw)

Scientific methods of analysis are often used for investigation of artworks, and this is also the case of the painting entitled “Vista do Desterro”, by Joseph Bruggemann, (1886) which is being restored at the Conservation-Restoration Atelier for Movable Cultural Heritage ATECOR in Culture Foundation of Santa Catarina – FCC. This study used UV imaging methods, infrared spectroscopy (FTIR) analysis and energy-dispersive X-ray (SEM-EDS) analysis to identify the constituent materials of the referred artwork and previous interventions on it. All the analyses showed that drying oil was used as a binder, and a layer of terpenic varnish was also found. The possibly original pigments found were the following: lead white, natural sienna, brown ocher, synthetic ultramarine and yellow ocher.
