Description
Amarna blue pigments (18 Dynasty, c. 1400 BC) painted on pottery fragments were investigated using the PIXE, XRF and XRD methods in laboratories and also using a portable type of X-ray spectrometer at the sites of excavation. On the blue-colored part enrichment of Na, Al, S, Cl, Ca, Mn, Co, Ni and Zn was found using X-ray spectroscopy, and CaSO4, NaCl and Co(M)Al2O4, M denoting Mn, Fe, Ni and Zn, were found by the help of X-ray diffraction. This means that Amarna blue is a mixture of CaSO4 and Co(M)Al2O4, at least in part.
