The thermoluminescence (TL) of Egyptian Blue

International Journal of Radiation Applications and Instrumentation. Part D. Nuclear Tracks and Radiation Measurements, 1988
Abstract Egyptian Blue is a synthesized crystalline pictorial pigment with formula CaCuSi 4 O 10 . It has been used in Egypt and Mesopotamia from the 3rd millenium B.C. A preliminary experiment on a recently synthesized samples showed that this pigment is thermoluminescent after β irradiation ( 90 Sr).

Color Alteration of Ancient Egyptian Blue Faience

International Journal of Architectural Heritage, 2013
Four different colored faience tiles were found in South Tomb of King Djoser in Saqqara, Egypt. The tiles suffer from various deterioration aspects, mainly color alteration, which occurred as a result of the reaction between present salts and the free copper ions of blue faience and changing it into greenish blue, dark green, and light green.

“Amarna blue” painted on ancient Egyptian pottery

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2002
Abstract “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

DIGITAL MAPING OF EGYPTIAN BLUE : CONSERVATION IMPLICATIONS

Studies in Conservation, 2010
AbstractEgyptian blue was extensively used throughout the areas surrounding the Mediterranean from early dynastic Egypt until after the Roman Empire ended. A new, easily applied, technique to detect and map this pigment has been developed that takes advantage of its very strong photo-induced infrared luminescence. Using this method, single particles of

THE EGYPTIAN GREEN PIGMENT: ITS MANUFACTURING PROCESS AND LINKS TO EGYPTIAN BLUE*

Archaeometry, 2003
The chemical and structural analysis of raw Egyptian blue and green pigment cakes and of 50 pigment samples taken from paintings kept in the Louvre Museum was performed using a set of analytical techniques (X‐ray powder diffraction, transmission and scanning electron microscopy, Raman microscopy and UV spectrophotometry).

Photoluminescence of the inorganic pigments Egyptian blue, Han blue and Han purple

Journal of Cultural Heritage, 2000
Abstract The room-temperature photoluminescence spectra of various samples of Egyptian blue (CaCuSi4O10) are presented, discussed and compared with those of recently synthesized compounds corresponding to the ancient pigments Han blue (BaCuSi4O10) and Han purple (BaCuSi2O6).

Spectroscopic Study of Egyptian Blue Mixed with Other Pigments

Helvetica Chimica Acta, 2003
AbstractThe Romans used a vast array of colors in their mural paints. The applied pigment mixtures containing Egyptian blue resulting in green, ochre, brown, gray, and white hues were studied. The chromatic characterization of wall paintings by electronic spectroscopy provided an easy and reliable procedure for the grouping of the samples to be studied
