The delicate shallow rounded sides exquisitely moulded in the form of slender fluted petals with pointed tips radiating from a slightly recessed flat centre simulating a chrysanthemum bloom, all supported on a foot of corresponding form, covered overall save for the footring and the centre of the base with an even bright lime-green enamel, the white centre of the base inscribed with an underglaze-blue six-character reign mark within a double circle. Yongzheng mark. D: 18.5 cm
