Month cups depicting seasonal flowers accompanied by pertinent two-line poems represent a classic design of the Kangxi period. Very delicately potted, they are painted in the proper
wucai palette of underglaze blue and overglaze enamels, which was devised in the Ming dynasty, but rarely used in the Qing, when the underglaze colour was generally omitted. On these month cups the designs are generally sketched on the unglazed porcelain in a faint underglaze blue.
Slight differences in size, colours, writing styles and marks between individual cups and different months suggest that even these cups may not have been produced as sets of twelve, but perhaps issued consecutively, as the year evolved, to be assembled at the end.
