This shape is inspired by a European prototype and may have been copying the Dutch glass and stoneware bottles which were used on ships in the 17th and 18th Centuries to transport alcoholic beverages and oil for lighting lamps. See J. Harrison-Hall, Ming Ceramics in the Briitish Museum, London, 2001, pp. 384 and 385, no. 12:79 for a larger bottle of this form. The author mentions that another example, with a late 17th Century Dutch silver mount, is in the Ashmolean Museum, Oxford. It would appear that a bottle of this size is extremely rare.
