Dish with design of flowers, underglaze blue

This dish, unusually for Nabeshima ware, has a flat interior and a strongly recurved rim. Five floral motifs with ray-like petals are scattered over the interior. This abstract design is fresh and crisp, but what is being alluded to is unclear: perhaps flowers, auspicious noshi strips bundled together to resemble flowers, or cut-paper flowers used in ceremonies. The pale lapis lazuli glaze (a translucent blue made by mixing the gosu of underglaze blue into the transparent glaze applied before the overglaze) on the interior has run slightly over the edge of the underside. The designs are in white resist and underglaze blue. The rim of the underside is entirely covered in interlocking thunderbolt arabesques with peony flowers at three equal intervals. A comb pattern circles the foot.
