The image shows the layout of one of the twelve reverberatory furnaces for quicksilver metallurgy that were built in the Calle de Santa Ana of the Real de minas de Azogue de Nuestra Señora de la Concepción in New Spain. These furnaces were made on the outside of brick and lime, to resist water, and on the inside of brick and clay, to preserve the fire. The picture explains how they worked.
