1. Blue-and-White Porcelain (青花瓷, Qinghua Ci)

One of the most iconic forms of Chinese porcelain, blue-and-white ware emerged during the Tang Dynasty (618–907) but reached its peak in the Ming (1368–1644) and Qing (1644–1912) dynasties. This style features intricate cobalt-blue designs painted on a white porcelain body, often depicting landscapes, dragons, flowers, and mythological scenes.

• Yuan Dynasty (1271–1368): Early blue-and-white porcelain was influenced by Middle Eastern tastes due to trade along the Silk Road.
• Ming Dynasty: The Xuande and Yongle periods produced some of the finest examples, with refined cobalt pigments.
• Qing Dynasty: The Kangxi and Qianlong emperors further perfected the technique, introducing more elaborate designs.

Blue-and-white porcelain remains highly collectible and has influenced ceramic traditions worldwide.

2. Celadon (青瓷, Qing Ci)

Celadon, known for its jade-like green glaze, dates back to the Shang Dynasty (1600–1046 BCE) and flourished during the Song Dynasty (960–1279). It was highly prized in China and exported to Southeast Asia, the Middle East, and beyond.

• Longquan Celadon: Produced in Zhejiang province, this type is famous for its thick, crackled glaze and subtle green hues.
• Ru Ware (汝窑): A rare and prestigious celadon made exclusively for the imperial court during the Northern Song Dynasty.

Celadon’s elegance lies in its simplicity, embodying the Confucian and Daoist appreciation for natural beauty.

3. Famille Rose (粉彩, Fencai) and Famille Verte (五彩, Wucai)

These colorful enameled porcelains became prominent during the Qing Dynasty.

• Famille Verte (“Green Family”): Uses green, red, yellow, and blue overglaze enamels, popular in the Kangxi period.
• Famille Rose (“Pink Family”): Introduced in the Yongzheng era, it includes soft pink and purple tones, often depicting courtly scenes, flowers, and birds.

These styles reflect the Qing Dynasty’s love for opulence and detail.

4. Doucai (斗彩, “Contending Colors”)

Developed in the Ming Dynasty, doucai combines underglaze blue outlines with overglaze colored enamels. The Chenghua Emperor’s reign (1465–1487) produced some of the finest doucai pieces, such as the famous “Chicken Cups.”

5. Blanc de Chine (白瓷, Bai Ci)

Originating from Dehua in Fujian province, this pure white porcelain is known for its milky glaze and delicate sculptural forms, particularly Buddhist statues and figurines. It gained popularity in Europe during the 17th and 18th centuries.

6. Jun Ware (钧窑, Jun Yao)

Famed for its stunning lavender and sky-blue glazes, Jun ware was produced during the Song Dynasty. Its unpredictable kiln effects, known as “flambé,” create unique patterns, making each piece one-of-a-kind.

7. Crackle Glaze Porcelain (哥窑, Ge Yao)

Characterized by intentional crackling in the glaze, Ge ware was highly valued during the Song Dynasty. The cracks, caused by differing cooling rates between the glaze and the body, were seen as a mark of beauty.

Production Techniques of Chinese Porcelain: Mastery Through the Ages

1. Clay Preparation and Purification

The foundation of porcelain lies in the quality of the clay, typically made from kaolin (高岭土, gaolingtu) and petuntse (瓷石, cishi).

• Levigation (淘洗, taoxi): Raw clay is mixed with water and left to settle, allowing impurities to sink. The refined slurry is then dried to a workable consistency.
• Pugging (练泥, lianni): The clay is kneaded to remove air bubbles, ensuring a smooth, even texture.

This meticulous process was perfected during the Tang (618–907) and Song (960–1279) dynasties, leading to the famous “true porcelain” of Jingdezhen.

2. Shaping Techniques

Chinese porcelain has been shaped using various methods, depending on the era and type of ware.

A. Hand-Molding (手塑, shousu)

• Used for sculptural pieces like Blanc de Chine figurines.
• Artisans shape the clay by hand or with simple tools.

B. Wheel-Throwing (拉坯, labei)

• The most common method for symmetrical vessels like bowls and vases.
• A potter’s wheel spins while the artisan shapes the clay, allowing for thin, delicate walls.

C. Slip Casting (注浆成型, zhujiang chengxing)

• Developed later for mass production.
• Liquid clay (slip) is poured into plaster molds, hardening into the desired shape.

D. Segment Joining (接坯, jiepi)

• Large or complex pieces (e.g., imperial vases) are made in sections and joined before firing.

3. Decoration Techniques

Chinese porcelain is renowned for its intricate decorations, applied at different stages of production.

A. Underglaze Decoration (釉下彩, youxiacai)

• Designs are painted on raw (unfired) clay before glazing.
• Blue-and-white porcelain uses cobalt oxide, which turns blue when fired.
• Red underglaze (釉里红, youlihong) uses copper oxide, requiring precise kiln control.

B. Overglaze Decoration (釉上彩, youshangcai)

• Enamels are applied after the initial glaze firing.
• Famille rose (粉彩, fencai) and famille verte (五彩, wucai) use vibrant mineral pigments.
• Doucai (斗彩, “joined colors”) combines underglaze blue outlines with overglaze colors.

C. Carving and Incising (刻花, kehua / 划花, huahua)

• Designs are etched into the clay before glazing.
• Celadon wares often feature delicate carved patterns.

D. Impressed Decoration (印花, yinhua)

• Stamps or molds press patterns into the soft clay.
• Common in Ding ware (定窑) of the Song Dynasty.

4. Glazing Methods

The glaze gives porcelain its luster and durability. Different techniques produce distinct effects.

A. Single-Fired Glazing (一次烧成, yici shaocheng)

• Glaze is applied to unfired clay, and both are fired together.
• Used in celadon and qingbai (青白) wares.

B. Double-Fired Glazing (二次烧成, erci shaocheng)

• The biscuit (unglazed) body is fired first, then glazed and fired again.
• Allows for more intricate decorations, as seen in Ming and Qing polychrome wares.

C. Flambé Glazing (窑变釉, yaobian you)

• Unpredictable kiln effects create dramatic colors, as in Jun ware (钧窑).
• Copper and iron oxides produce streaks of purple, blue, and red.

D. Crackle Glaze (开片, kaipian)

• Intentional cracking is achieved by cooling the glaze faster than the clay body.
• Ge ware (哥窑) and Guan ware (官窑) are famous for this technique.

5. Firing Techniques

The kiln type and firing process determine the final appearance of the porcelain.

A. Dragon Kilns (龙窑, longyao)

• Long, sloping kilns built into hillsides.
• Used since the Han Dynasty (206 BCE–220 CE) for high-temperature firings.

B. Mantou Kilns (馒头窑, mantouyao)

• Dome-shaped kilns, efficient for controlled oxidation/reduction firing.
• Common in northern China for Jun and Ding ware.

C. Wood-Fired Kilns (柴窑, chaiyao)

• Traditional method using pine wood, creating subtle ash effects.
• Jingdezhen’s imperial kilns used this method for the finest porcelains.

D. Reduction Firing (还原烧, huanyuan shao)

• Oxygen levels are restricted, turning iron oxide into a blueish tone (seen in celadon).

The production of Chinese porcelain is a testament to centuries of innovation, blending chemistry, artistry, and engineering. From the careful selection of clay to the mastery of glazing and firing, each technique contributes to the uniqueness of Chinese ceramics. These methods not only shaped China’s cultural heritage but also influenced global ceramic traditions, making Chinese porcelain one of the world’s most enduring artistic legacies.

Conclusion

Chinese porcelain is not merely a craft but a reflection of China’s philosophical, aesthetic, and technological evolution. From the understated elegance of celadon to the vibrant hues of famille rose, each style tells a story of dynastic patronage, trade, and artistic innovation. Today, these porcelain traditions continue to inspire artists and collectors, preserving China’s rich cultural heritage for future generations.
