A strikingly fine Kangxi period Chinese export porcelain blue and white molded bowl with a barbed edge, with a luminous glaze over the intensely cobalt blue decoration depicting a dragon chasing the flaming pearl above a lower register of lotus petal panels each individually painted with waves and foliate decoration, The interior just as interesting with a carp rising from the waves a cloud emanating from his mouth containing another dragon image, the rim border continuing the wave and floral motif of the exterior panels. Measuring 8″ in diameter and in good condition with a professional restoration to a U-shaped piece out of the rim with a short associated line. Circa 1690 and with a history of ownership by President Herbert Hoover.
