Spectrochemical and structural studies on a roman sample of Egyptian blue

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 1995
Abstract A ball of Egyptian blue excavated on the archaeological site of Augusta Praetoria (Aosta, Italy) has been investigated by several techniques. Optical microscopy and X-ray diffraction gave proof of the identity of the pigment, while indicating that silica phases had also been formed because of sand excess in the reaction mixture.

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.

Egyptian blue: modern myths, ancient realities

Journal of Roman Archaeology, 2016
Colours containing bright and saturated blue hues were popular for painterly effects in most of the Mediterranean cultures dating from the Bronze Age to the fall of the Roman Empire. Pigments providing the desired blue were produced from precious minerals such as azurite and lapis lazuli, but bright blue hues also came from pigments produced by merging

“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 ...

Egyptian Blue in the Polychromy of the Acropolis Monuments: An Analytical Investigation

Journal of Raman Spectroscopy
ABSTRACT Egyptian blue (EB), considered the first artificial pigment in history, exhibits an intense blue color and chemical stability over time. Throughout antiquity, EB was widely used to decorate architectural structures, sculptures, and artifacts.
