The Story Behind the Blue: A Simple Guide to Chinese Blue-and-White Porcelain
The color blue holds a special place in the history of Chinese ceramics. Its rise in importance began during the Tang dynasty (618–907), when potters used cobalt ore, imported from Persia, to create deep blue designs on pottery and porcelain. At that time, cobalt was rare and expensive, so potters used it sparingly.
Later, during the Yuan (1279–1368), Ming (1368–1644), and Qing (1644–1911) dynasties, Chinese artisans refined their use of cobalt. They developed different shades of blue, depending on the type of ore and how they applied it. This led to the famous blue-and-white porcelain we know today.

Where the Blue Came From
The blue pigment in Chinese porcelain came from cobalt, a mineral mined in West Asia as far back as 2000 B.C. It first appeared in glassmaking in China during the Warring States period (475–221 B.C.). When cobalt arrived in China through the Silk Road, potters started using it on earthenware, alongside other glazes. This helped develop the well-known three-colour “sancai” style.
But cobalt didn’t catch on right away. During the Song dynasty (960–1279), potters focused on single-colored ceramics. They believed cobalt was too challenging to use correctly. That changed in the Yuan dynasty, when Mongol rule brought new ideas and tastes. Under their rule, blue-and-white porcelain became a symbol of power and luxury.

Religion, Trade, and Taste
Mongol rulers had deep cultural ties to the color blue. Their legends told of a “hazy blue wolf” and a “white fallow deer” as their mythical ancestors. So it made sense that they favored blue-and-white porcelain for special events and diplomatic gifts.
Artisans in this period used a special type of cobalt called “Samarra Blue” or “Sumatra Blue,” which was rich in iron. This created dark blue patches, known as “heaped and piled” effects, on the surface of the porcelain. These designs stood out and became a signature of Yuan dynasty ceramics.
The best pieces were given to local leaders or sent abroad as gifts and trade goods. Blue-and-white porcelain became one of China’s most admired exports.
Ming dynasty, Early 17th century
The Ming Dynasty: Blue Reaches Its Peak
During the early Ming dynasty, especially under Emperors Yongle (1403–1425) and Xuande (1426–1435), Chinese potters pushed blue-and-white porcelain to new heights. Admiral Zheng He’s famous sea voyages brought back cobalt, called “smalt cobalt”, from across Asia. This cobalt created rich, deep blue tones.
Potters also improved how they fired the porcelain. They used better kilns and more careful techniques, allowing them to control how the blue tones appeared. These changes made the designs more elegant and detailed.
But cobalt wasn’t always easy to get. During the Hongwu reign (1368–1398), China restricted foreign trade. That forced potters to turn to locally mined cobalt. This cobalt, high in manganese, produced softer and lighter blue tones.
From the Chenghua period (1465–1487) to Zhengde (1506–1521), most blue-and-white porcelain used this local cobalt. Though it lacked the boldness of imported cobalt, many emperors preferred its subtle look.
Mixing Cobalts, Creating New Tones
Potters didn’t stop experimenting. In Jiangxi province, they found a local cobalt called “Mineral Blue.” This created a dull, lead-colored blue, often used in everyday pottery called minyao. But when mixed with “Muslim Blue”, a high-quality cobalt from Central Asia and China’s western provinces, it produced stunning purplish tones. Depending on the amount used, the glaze could range from silvery to violet blue.
Each emperor had personal preferences. The Xuande Emperor liked intense purplish blues with the “heaped and piled” look. The Chenghua Emperor, on the other hand, favored a lighter, more faded tone. These preferences shaped how artisans mixed and used cobalt during their reigns.
Experts often describe three key periods in the history of blue-and-white porcelain:
First peak: Yuan dynasty (1279–1368)
Second peak: Ming dynasty, especially from Yongle to Chenghua (1403–1487)
Third peak: Late Ming to early Qing, known as the “Transitional Period” (1611–1722)
The Rise of Local “Zhejiang Blue”
During the Transitional Period, local cobalt gained new attention. In Zhejiang province, miners extracted cobalt from Shaoxing, Jinhua, and Quzhou counties. This “Zhejiang Blue” produced intense, bright blues with a rich, almost 3D effect. Potters used it to make striking blue-and-white pieces during the reign of Kangxi (1662–1722), one of the most famous emperors of the Qing dynasty.
Why It Still Matters

These ceramics also had a significant influence outside of China. Persian, Japanese, and European potters all created their own versions after seeing Chinese originals. For example, Dutch “Delftware” copied many Chinese patterns and shapes.
As one Chinese art expert said:
“Blue-and-white porcelain is more than just decoration. It’s a story of global trade, cultural taste, and artistic skill.”
Final Thoughts
Chinese blue-and-white porcelain is not just art, it’s a piece of history. It shows how one color, used by skilled hands, became a symbol of beauty, trade, and culture across the world.
From the deserts of Persia to the kilns of Jingdezhen, from royal courts to folk markets, this blue tells a rich and lasting story. And that story continues to inspire collectors, artists, and admirers today.
