GABRIELA SIRACUSANO PDF

In this interview with Portal editor Susanna Sharpe, Siracusano discusses her work. Salta, Argentina. Cathedral of Salta. You ended up becoming an expert in South American colonial art in a circuitous way. That led me in , as a graduate student, to start a research project on the Argentine concrete artists of the s and 50s and their particular appropriation of the scientific ideas associated with quantum physics. After five years of work, and having written almost half of my thesis, I felt something was wrong: there were no more questions aroused inside me on that topic.

Introduction: Carbon-based pigments are a group of dark-colored materials, which are classified according to the starting material used and their manufacturing process. Raman spectroscopy is an ideal technique for the identification of Raman spectroscopy is an ideal technique for the identification of carbonaceous matter. The aim of the present study was the identification of carbon-based pigments in four polychrome wooden sculptures from the Jesuit Mission La Trinidad in Paraguay. Results: Analysis of the Raman spectral parameters of the polychrome samples and comparison with those of carbon-based pigment references allowed the identification of wood charcoal, lampblack, bistre and a black earth pigment.

Complementary analysis by infrared spectroscopy and elemental analysis supported the assignments. Conclusions: In this study we have provided new evidence that Raman microscopy is a powerful technique for the discrimination of carbon-based pigments in works of art. This is the first time that bistre, lampblack and a black earth pigment are identified in colonial art. The chemical information obtained on the black pigments contributed to increase our knowledge on available resources and technology used in the manufacture of the polychrome sculptures at the Jesuit Mission.

This information is relevant for our studies on Colonial art. Research Interests:.
