Bowl 1430-1460 Spanish The technique of lusterware involves the use of a copper oxide which, when painted on in the desired patterns and fired separately, produced a metallic sheen in tones ranging from pale gold to deep reddish copper depending on the proportions of the mixture. This bowl, probably a remnant of a larger table service, was made for export for the Dazzi family of Florence, whose arms it bears. Italy was a major market for the Manisan pottery industry, and certain Spanish designs, such as the bryony leaf pattern on this bowl, were emulated by Florentine potters.. Bowl 471809
