As seis pinturas de Massimo Campigli do MAC USP discutidas sob o olhar das artes plásticas e dos resultados de análises com técnicas de imagens e espectroscópicas

This article focuses on the discussion of the results obtained with non-invasive image and spectroscopic analyzes (to determine chemical elements and compounds) on the six paintings by the German artist, naturalized Italian, Massimo Campigli, that belong to the collection of the Museum of Contemporary Art of the University of São Paulo (MAC USP). Aspects of the artist’s trajectory, the plastic solutions of the artworks, along with the analyzes made with the spectroscopic techniques of energy dispersive X-ray fluorescence (ED-XRF), Raman, and Fourier transform infrared (FTIR), and the imaging techniques of visible photography (VIS), raking light (RAK), transmitted light (TRANS), visible ultraviolet fluorescence (UVF), infrared reflectography (IRR), and radiography (RAD) offer important information on the artist and on his work. These non-invasive analyzes were carried out in the museum itself with portable equipment from the Laboratory of Archaeometry and Applied Sciences to Cultural Heritage (LACAPC) of the Physics Institute (IF) of USP. Overall, the results obtained corroborate with Campigli’s testimonies about his artistic practice, as well as those of people who saw him working in his studio. His palette choice, composed by natural and synthetic pigments, mostly whites and paints with earthy tones, and his creative steps of creating and recreating the paintings, reusing canvases many times, were proven to be true with the analytical investigations. O presente artigo discute os resultados obtidos com as análises de imagens e espectroscópicas (para determinação dos elementos e compostos químicos) não invasivas realizadas em seis pinturas do artista alemão, naturalizado italiano, Massimo Campigli pertencentes ao acervo do Museu de Arte Contemporânea da Universidade de São Paulo (MAC USP). Os aspectos da trajetória do artista, as soluções plásticas das obras somadas às análises feitas com técnicas espectroscópicas de fluorescência de raios X por dispersão de energia (FRX-DE), Raman, e infravermelho com transformada de Fourier (FTIR), e com técnicas de imageamento como fotografia sob luz visível (VIS), luz rasante (RAS), luz transmitida (TRANS), fluorescência visível induzida por radiação ultravioleta (UV-VIS), reflectografia de infravermelho (RIV) e radiografia (RAD) fornecem importantes informações sobre o artista e sua obra. As técnicas analíticas não invasivas foram realizadas no próprio museu e com equipamentos portáteis do Laboratório de Arqueometria e
