The form of the teapot is derived from a combination of different elements of three engraved designs for a water ewer, a two-handled vase and a two-handled bowl engraved by Françoise Bonzonnet for Jacques Stella's publication Livre de vase (Paris, 1667), plates 17, 23 and 44 respectively. Plates 17 and 23 are illustrated opposite.
Two teapots of the same form from the Grand Dukes of Baden Collection were sold by Sotheby's, Baden-Baden, 5th-21st October 1995, lots 1308 and 1333. For a coloured example, see Erika Pauls-Eisenbeiss, German Porcelain of the 18th Century (London, 1972), Vol. I, pp. 512-513, where other examples are listed.
