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

Color Alteration of Ancient Egyptian Blue Faience

International Journal of Architectural Heritage, 2012
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

Investigating the use of Egyptian blue in Roman Egyptian portraits and panels from Tebtunis, Egypt

Applied Physics A, 2015
The use of the pigment Egyptian blue is investigated on a corpus of fifteen mummy portraits and Roman-period paintings from Tebtunis, Egypt, housed in the Phoebe A. Hearst Museum of Anthropology at the University of California, Berkeley. Egyptian blue has a strong luminescence response in the near infrared that can be exploited to created wide-field ...
