A short 1869 article from The Manufacturer and Builder on chrome green pigment, reprinted from Moniteur Scientifique. It describes how MM. Casthelaz and Leune prepared a brilliant emerald 'imperial green' by slowly precipitating chrome salts by the wet process, using reagents such as zinc oxide, zinc carbonate, gelatinous alumina, iron or zinc. It presents this as a safer replacement for copper and arsenic greens in printing on stuffs, paper, paints, glass and ceramics.
