An evergreen blue. Spectroscopic properties of Egyptian blue from pyramids to Raphael, and beyond
Inorganica Chimica Acta, 2022 Egyptian blue, the oldest man-made blue ever, invented by the Egyptians around 5000 years ago has newly raised to prominence for its very recent finding on Raphael's Roman fresco the Triumph of Galatea hosted in Villa Farnesina, Rome. This is the first case in the Renaissance after centuries of oblivion.

An EPR study on ancient and newly synthesised Egyptian blue
Talanta, 2006 Two sets of ancient Roman Egyptian blue (EB) samples and one set of EB samples synthesised in our lab, were analysed by EPR spectroscopy, a technique not commonly used in this field. The spectroscopic parameters obtained were used to attempt the discrimination of the provenance and of the manufacturing techniques of the investigated samples.

Making and working Egyptian blue – a review of the archaeological evidence
Journal of Archaeological Science, 2023 As the earliest artificial pigment, Egyptian blue has a millennia-long history of production, processing/working, and use. This paper offers a review of the published archaeological evidence for Egyptian blue production, aiming to identify common and potentially diagnostic criteria for each process step to aid future identification and interpretation ...

Exfoliation of Egyptian Blue and Han Blue, two alkali earth copper silicate-based pigments. [PDF]
J Vis Exp, 2014 In a visualized example of the ancient past connecting with modern times, we describe the preparation and exfoliation of CaCuSi4O10 and BaCuSi4O10, the colored components of the historic Egyptian blue and Han blue pigments. The bulk forms of these materials are synthesized by both melt flux and solid-state routes, which provide some control over the ...
