A fine and very rare yellow ground 'dragon' bottle vase mark and period of Daoguang

the globular body supported on a gently flared foot, rising to a tall slightly waisted neck, the exterior incised and boldly painted with two scaly five-clawed dragons chasing a single 'flaming pearl', one painted green, flying amidst green and brown flames and swirling clouds, the other painted  brown, swimming through turbulent crested waves all between a band of interlinked ruyi-heads at the rim and a keyfret band on the foot, all against a lemon yellow ground extending to the interior, the base incised with a six-character sealmark

See a Jiaqing bottle vase painted with green dragons on a yellow-ground, possibly the inspiration to the present vase, in the National Palace Museum, Taipei, illustrated in Sekai toji zenshu, vol. 15, Tokyo, 1983, col. Pl. 236.
