Análise química de pigmento vermelho em osso humano
This work presents a chemical study of human bones painted red located at the Morro dos Ossos site, Piauí State, Brazil. The pigment was studied using X-ray diffraction (XRD), energy dispersive spectroscopy (EDS), scanning electron microscopy (SEM), complexation reactions with thiocyanate and UV-Vis absorption spectroscopy. The results confirmed the presence of ochre and that the pigment layer is essentially composed of a mixture of clay and hematite, α-Fe2O3.
