The Rarest Blue: The Remarkable Story of an Ancient Color Lost to History and Rediscovered
"Sterman's expansive and fascinating microhistory covers the historical importance of the dye, the closely guarded manufacturing process, controversies over fraudulent versions of the color, the chemistry behind the dye molecule, the events leading to the rediscovery of the dye process, and even the physics explaining the rarity of the color in nature. Although Sterman tackles a broad range of topics, his emphasis on Jewish traditions and ancient practices keeps it centered and illuminating."
