Rookwood Pottery

Founded in Cincinnati by Maria Longworth Nichols in 1880, Rookwood became one of the most important American art potteries—known for technical innovation, exceptional decorators, and an unusually informative system of factory and artist marks.

History

A Cincinnati original.

Rookwood grew from Nichols’s determination to establish an American pottery capable of competing artistically with European and Japanese ceramics. The pottery developed painterly underglaze decoration, distinctive glaze lines, and a studio system in which individual decorators often signed their work.

Its production ranged from one-of-a-kind artist-decorated vessels to architectural faience and later commercial lines. Historic Rookwood production continued into the twentieth century; the modern company operates today in Cincinnati.

Rookwood designer and decorator

Kataro (Kitaro) Shirayamadani

An important distinction: a Rookwood vase bearing Shirayamadani’s cipher was designed or decorated by him within Rookwood’s studio system. That does not mean he personally formed or “made” the pottery body with his own hands.

Japanese-born Shirayamadani joined Rookwood in 1887 and became one of the pottery’s most celebrated artists. His work includes Japanese-inspired subjects, flowers, landscapes, animals, dragons, and deeply carved or modeled surfaces.

He worked as a designer and decorator across changing Rookwood glaze lines. Collectors generally recognize an interlaced KS-style cipher, but a signature should be compared with documented examples and read together with the factory mark, date code, shape, and decoration.
