This is a very good mid to large size Hydra jug or Pitcher made by the Davenport Company of Longport, Staffordshire, England in the late Georgian period, circa 1805-1820, made of Ironstone pottery, which Davenport called Stone China.
 
It is hand decorated over a blue printed outline, in an Imari Pattern called Jardinière, which is one of their very decorative chinoiserie designs that was also used by Mason's Ironstone. The hand painted enamels are bold and and bright with additional hand gilded detail. An identical Davenport jug is illustrated in Godden's Guide to Ironstone, a reference book by Geoffrey A. Godden, Published by The Antique Collectors Club, page 230, Plate 178. Davenport jugs and pitchers are generally of higher quality than Mason's Ironstone and have heavily gilded detail, with finer hand painting.
 
The jug has the blue Davenport Stone China printed anchor mark to the base as used by them between 1805 and 1820.
