Castillo Polychrome Majolica - National Parks Gallery

Castillo Polychrome was made in the late 17th century and has white paste and white background enamel, with naturalistic designs painted in light blue, and thin black lines emphasizing the design. Some vessels also have cross hatching and arches. Majolica is a wheel-thrown pottery, made with a soft earthenware paste covered with a tin glaze, and are generally shaped in the form of deep brimmed plates or bowls. Most of the majolica found in St. Augustine was made in Mexico between the late 16th century and the 18th century.
