Pieces with a decoration in black ground, like these vases, were known in Europe as famille noire wares. They were relatively rare in the West. In this case, mounts have been added to transform the vases into pastille burners for the burning of incense or other sweet substances. On opposite sides of the shoulders are two Chinese figures, each with a ponytail and earrings. The design of their skirts matches some of the exterior architectural details at the Royal Pavilion, Brighton, where the vases were displayed by George IV (1762–1830).
