清康熙 黑地素三彩四方瓶 Chinese. The tapering sides divided into four facets, decorated with various flowers, antique vases, birds enclosed within shaped cartouches, all reserved against a rich black ground, the base painted with a 'leaf' motif. 19th century, Late Qing Dynasty period. 此瓶為四方形制，成形不易。非琢器拉胚成形，而是預先做好四片，後拼貼而成，全過程沒有拉胚工具協助，靠手塑造，極其考究工匠的工藝水平，撇口，束頸，四方底。器身施黑彩為地，開窗繪各種紋飾，構圖嚴謹，紋飾優美。底部“青花樹葉紋款”，為康熙典型款識。
