📜 Origin & History

Porcelain Blue originates from cobalt ore. The Tang Dynasty saw embryonic forms of blue-and-white ware, but it truly matured in the Yuan Dynasty. The 'Sumali Blue' cobalt material imported from Persia at the time had a high iron content, producing a unique effect of brilliant blue with black iron-rust spots after high-temperature underglaze firing.

Yuan Dynasty blue-and-white porcelain is known for large forms and dense decoration. Artisans painted patterns with cobalt material on the unfired body, applied a transparent glaze, and fired it once in a kiln at about 1280 degrees in a reducing atmosphere. The blue shone brilliantly under the transparent glaze, like ink wash diffusing on rice paper.

Blue-and-white porcelain reached its peak during the Yongle and Xuande reigns of the Ming Dynasty. Zheng He's voyages to the Western Seas brought back high-quality 'Sumali Blue,' making official ware blue like gemstones. Later, the Chenghua Emperor preferred elegance, switching to domestic 'Equal Blue,' which created the delicately beautiful 'Chenghua Blue-and-White' style.

In the late Ming and early Qing Dynasties, blue-and-white porcelain was exported in large quantities to Europe. The Dutch East India Company monopolized the trade, and Porcelain Blue became an Eastern color craze among European nobility. European countries built factories to imitate it, giving birth to European blue-and-white schools like Delftware.

Porcelain Blue remains an iconic color of Chinese culture today. It transplants the brush and ink conception of traditional Chinese ink wash painting onto porcelain, using one color to replace five, seeking infinite variation in simplicity, embodying the highest realm of Chinese aesthetics: 'extreme brilliance returning to plainness'.
