Rare and Expensive Blue Pigment Found in the Dental Calculus of a Medieval-Era Woman (2 of 8) (IMAGE)
Caption
Few blue pigments were known to the European medieval painter: lapis lazuli, cobalt smalt, azurite, cuprorivaite, malachite, and vivianite. However, among these, only lapis lazuli and azurite were widely used, and lapis lazuli was by far the most prized. This material relates to a paper that appeared in the Jan. 9th, 2019, issue of Science Advances, published by AAAS. The paper, by A. Radini at University of York in York, UK, and colleagues was titled, "Medieval women's early involvement in manuscript production suggested by lapis lazuli identification in dental calculus."
