Fungal deterioration of a Jesuit South American polychrome wood sculpture
Pigment samples obtained from a South American Jesuit wooden sculpture housed at the Museum of Natural Sciences in La Plata, Buenos Aires province, Argentina, were characterized using scanning electron microscopy and energy dispersive X-ray microanalysis and infrared spectroscopy. The red pigments w...
