Estudo técnico da tela Efeitos de luz num armazém de Abel Salazar: um trabalho representativo da sua produção pictórica final

This article discusses some of the creative processes of Abel Salazar (1889 – 1946), based on documentary sources and reinforced by reconstructions of pictorial techniques of the author. It addresses the technical and material study of a large format painting on canvas, Efeitos de luz num armazém, such as the characteristics of support, ground, drawing and painting. For this study we used different examination and analysis methods, namely photography of visible light spectrum, UV and IR to the painting; observation by optical microscopy (OM) and analysis with Scanning Electron Microscopy with X-ray microanalysis (SEM-EDS) and micro Fourier transform infrared spectroscopy (μ-FTIR) from samples taken from the piece. Analytical results are presented and complemented the identification of the technical procedures in order to determine the materials that constitute the canvas.
