Egyptian blue ? Cuprorivaite a window to ancient Egyptian technology

Naturwissenschaften, 1983
Egyptian Blue, a multicomponent synthetic blue pigment has been recorded in ancient Egypt since the Fourth Dynasty of the Old Kingdom (2600–2480 B.C.). The pigment consisting of cuprorivaite (CaCuSi4O10) with variable amounts of wollastonite (CaSiO3), Cu-rich glass and cuprite (Cu3O) or tenorite (CuO) was prepared by melting the copper-rich ingredient ...

A short note on Egyptian blue

Journal of Cultural Heritage, 2004
Abstract We studied first the feasibility of the reaction synthesis of EB in molten alkaline carbonates; then we changed to “solid phase” syntheses, comparing the yields according to the proportion of the various components. In molten carbonates azurite was produced, which turned to malachite at room temperature.

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

Investigating the provenance of Egyptian blue pigments in ancient Roman polychromy

Archeometriai Műhely, 2021
Egyptian blue is a copper-based blue pigment that was widely used across the Mediterranean from ca. 3300 BC up to late antiquity and even later. For this case study, we analyzed the provenance of Egyptian blue from a Campana relief from the collection of the Ny Carlsberg Glyptotek, Denmark. Campana reliefs are terracotta plaques, which were named after
