Blue and white porcelain, also known as underglaze blue and white, is one of the most iconic forms of Chinese ceramics. It is created by painting designs with cobalt-based pigments onto a ceramic body, which is then covered with a transparent glaze and fired at high temperatures in a reducing atmosphere. The result is a striking blue color that remains vibrant and stable over time. Cobalt, the key ingredient, offers strong coloring power, bright hues, and a high firing success rate, making it ideal for decorative pottery.
The origins of blue and white porcelain date back to the Tang Dynasty, though it was not yet fully developed. Early examples, such as those found in Yangzhou, suggest that these pieces were likely made for export. During the Song Dynasty, blue and white began to evolve, but it wasn’t until the Yuan Dynasty that the technique reached maturity, particularly in Jingdezhen, where the famous Hutian Kiln produced refined blue and white wares. By the Ming Dynasty, blue and white had become the dominant style, and during the reign of Emperor Kangxi in the Qing Dynasty, it reached its peak, with innovations like multi-colored blue and white patterns.
In the Tang Dynasty, blue and white porcelain was still in its early stages. Excavations in Yangzhou have uncovered more than 20 pieces, including bowls, jars, and vases, often decorated with floral motifs. These pieces used low-manganese, low-iron cobalt, likely imported from Central Asia, giving them a rich greenish-blue hue. The clay was thick and porous, resulting in a grayish tone, while the glaze was yellow and uneven. Most items were small, with intricate designs, suggesting they were intended for trade rather than domestic use.
During the Song Dynasty, blue and white porcelain remained relatively rare. Only a few fragments have been found, mostly in Zhejiang Province. These pieces show simpler patterns, such as chrysanthemums and circular motifs, and used local cobalt sources. Unlike the Tang-era pieces, they were not directly connected to the earlier blue and white tradition.
By the Yuan Dynasty, blue and white porcelain became more advanced, thanks to the addition of kaolin, which improved the strength and durability of the clay. The glazes were whiter and more opaque, and the designs became more elaborate. Artists used both domestic and imported cobalt, producing a range of blue tones—from deep indigo to lighter shades. Common shapes included large bowls, cups, and vases, often adorned with dragons, phoenixes, and floral patterns.
In the Ming and Qing Dynasties, blue and white porcelain flourished. The Yongle and Xuande periods marked a golden age, with exquisite craftsmanship and refined aesthetics. Under Kangxi, new techniques emerged, such as the use of multiple colors in blue and white designs. However, after Qianlong, the popularity of blue and white declined due to the rise of enamelware. Despite a brief revival in the late Qing, it never regained its former glory.
Throughout its long history, blue and white porcelain has reflected the cultural and artistic evolution of China, blending technical innovation with aesthetic beauty. Its influence extended far beyond China, shaping ceramic traditions across Asia and the Middle East. Today, it remains one of the most celebrated and enduring art forms in the world.
