This ornithomorphic jug is also known as  a ‘surprise jug’ or a ‘trick jug’, its openwork sides concealing a double bottom intended to surprise the user. A flattened, circular reservoir is connected to the pouring spout, shaped like a bird’s head, in an unusual and complex design that indicates a work considerable some skill. The decoration consists of floral motifs and pieces of Orientally inspired furniture. There is no doubt that it dates from the last quarter of the 17th century, when the earthenware produced by the Poterats was becoming more varied and adapting to the fashion for monochrome blue and Chinese decorations.
