Wu Desheng Zisha Taocihang [Wu Desheng Purple Clay Pottery Company] was established in the 5th year of Republican Period in 1916 by Wu Hanwen, a zisha master and an entrepreneur from Dingshu in Yixing, who started as a potter in Yixing and later founded his own shop, where the commercial seal mark Jinding Shangbiao was used in the 20th century.

吳德盛紫砂陶器行於民國五年（1916年）為宜興鼎署鎮人吳漢文所創建，為當時專營紫砂的唯一商號。早期以「吳德盛」陽文籇書小方章為印，稍後為陽文籇書大方章「吳德盛制」，中期亦以大圓章陽文籇書「吳德盛制」、「宜興吳德盛制」為印。至二十年代下半葉，吳漢文為店號創立著名商標「金鼎商標」，其印款中央以鼎為圖案，四角為陽文楷書「金鼎商標」，為「吳德盛」店號訂壺專用印款。
