The type of formal decoration seen on the present vase, that of a dense design of flower scroll executed in rich famille rose enamels which are then enhanced on a bright monochrome ground, is found on other vases and jars of Jiaqing date. See a meiping of Jiaqing date in the Palace Museum, Beijing, illustrated in The Complete Collection of Treasures of the Palace Museum, Porcelains with Cloisonne Enamel Decoration and Famille Rose Decoration, Hong Kong, 1999, p. 195, no. 172, where the decoration of lotus scroll, like the present vase, is on a lime-green ground, but also includes Buddhist emblems and shou characters. Also see a lime-green ground bottle vase with famille rose lotus scroll design incorporating butterflies and bats illustrated by G. Avitabile in From the Dragon’s Treasure, Chinese Porcelain from the 19th and 20th centuries in the Weishaupt Collection, London, 1987, p. 33, no. 23.
