The Kangxi Emperor first became deeply interested in the foreign imported enamelled metalwork and set up an enamel workshop inside the palace to facilitate the local production of these exotic metal-bodied wares. The enamels used to paint on metalwork during this period were mostly foreign imports, and the Kangxi Emperor even enlisted the French Jesuit missionary, Jean-Baptiste Gravereau, in 1719 to train native artisans at the enamel workshop the skills of enamelling. Many of the enamels on metal that were produced during the period were inscribed with a Kangxi Yuzhi mark, reflecting his admiration for luminous metalwork like the current example, and the miniature vase offered as the previous lot in the current sale.
The richly painted pattern on the current example, with a variety of colour gradations, attests to the advanced level of skills achieved by the palace enamellers during the Kangxi period.
