The Consubstantiation of Pigment, Mineral Ore, and Bronze Corrosion in Late Imperial China

Azurite and its connatural counterpart, malachite, are unique substances that challenge conventional artistic taxonomies in Chinese art. As fine powder, the minerals were pigments for painting. As mineral ore, they were precious treasures in stone connoisseurship and were carved into a variety of scholarly collectibles and curios. Bronze vessels with blue and green corrosion were highly valued among antiquarians, and azurite and malachite were regarded by some as bronze corrosion in traditional China. After discussing the textual records that substantiate the versatility of these minerals, this paper focuses on two objects from the Qing dynasty, arguing that Chinese artists could draw on connections between the minerals and their connotations to conflate pigments, mineral ore, and bronze corrosion in their artworks. The first object is a painting by Ren Xun (ca. 1835-1893) depicting the renowned antiquarian Wu Dacheng (1835-1902) surrounded by bronze vessels from his collection. Some of the vessels were lavishly adorned with azurite and malachite, indicating excessive corrosion from old age and Wu’s connoisseurship. The second object is a curio in the shape of a bronze vessel made entirely of azurite, malachite, and other multicolored connatural substances. The kaleidoscopic appearance of the ore, together with the dexterity of its carver, perfectly transforms it into an excessively corroded bronze vessel. Both artists emulate the magical hand of nature and make minerals consubstantial with the objects and concepts that they represent.
