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.

Description

An early cobalt blue pigment used on pottery in Egypt (18 Dynasty, c. 1400 BC). Analaysis of the blue colorant in pottery fragment (Ude et all 2002) indicated it is composed of Co(M)Al2O4, where M denotes Mn, Fe, Ni and Zn. Gypsum was also found with the Amarna blue.
