From Stone Age to Celadon Age
A Journey Through Clay, Fire, and Time
Earth, Fire, and the Human Touch
Long before kings ruled and poets wrote, early humans discovered the art of shaping earth and fire into vessels. In the Stone Age, pottery was born - not for beauty, but for survival. Yet as centuries passed, what was once purely practical became deeply cultural.
In the low, humid lands of today's Zhejiang Province, two Neolithic cultures - Hemudu and Majiabang - made early pottery with black and red clays, marked by cords, carved lines, and a desire to make everyday tools into something more. These modest beginnings were the first flickers of what would eventually become one of the world's most refined ceramic traditions: celadon.
The Emergence of Celadon
By the Eastern Han Dynasty (25–220 CE), Chinese potters had begun producing green-glazed stoneware that marked the earliest phase of what would become known as celadon. Through experimentation, they discovered that adding iron oxide to the glaze and firing it in a reduction atmosphere created a gentle, translucent green hue reminiscent of jade—a stone revered in Chinese culture for its associations with purity, virtue, and spiritual power. These early wares, particularly from the Yue kilns in Zhejiang, were still rough in execution but showed immense promise. Their subdued tones and smooth surfaces suggested that ceramics could be more than utilitarian objects—they could also reflect beauty, symbolism, and social meaning.
As the techniques matured, celadon evolved into a sophisticated and culturally significant art form. Its jade-like glaze became a visual metaphor for moral ideals and philosophical values, embodying principles of harmony, modesty, and refinement central to Confucian and Daoist thought. Beyond its aesthetic appeal, celadon served political and ceremonial roles—used in imperial courts, religious offerings, and diplomatic gifts—signifying prestige and cultural authority. What began in the Eastern Han as a technical innovation thus grew into a timeless expression of Chinese artistic identity, influencing generations of potters and shaping ceramic traditions throughout East Asia.
Longquan: Kilns of Mist and Jade
Tucked into the lush, mountainous landscape of southern Zhejiang Province lies the city of Longquan - a place where clouds linger in valleys and rivers cut through forested slopes. This mist-shrouded terrain gave birth to one of China’s most iconic ceramic traditions, renowned not only for its technical mastery but for the quiet poetry embodied in every jade-toned piece.
Longquan’s geographical setting was ideal for ceramic production. The region possessed rich deposits of kaolin clay and feldspar, clean river water for mixing and glazing, and an abundance of pine wood for firing traditional dragon kilns. The humid climate and seclusion fostered centuries of focused craftsmanship, with techniques and recipes passed down through generations of potters.
From Function to Aesthetic Philosophy
The development of Longquan celadon was not a sudden innovation but the culmination of centuries of experimentation. Influenced by earlier Yue celadon from the northern part of Zhejiang, Longquan artisans pushed the boundaries of both form and glaze. By the Northern Song Dynasty (960-1127), the kilns in Longquan began producing wares with thick, glossy glazes in soft green tones. During the Southern Song (1127-1279), after the imperial court relocated to nearby Hangzhou, demand for refined ceramics surged - and Longquan rose to prominence.
Artisans began to favor:
The glaze - the hallmark of Longquan celadon - became thicker and more lustrous, pooling in carved recesses to highlight incised designs. The best pieces seemed to glow from within, resembling polished jade - a material long considered the essence of moral virtue in Chinese thought.
Technological Innovation: The Dragon Kiln
A key factor in Longquan's rise was the use of the dragon kiln - a long, sloping kiln built into a hillside, capable of reaching high temperatures and firing hundreds of pieces at once. The reduction atmosphere created by controlling oxygen levels during firing allowed the iron oxide in the glaze to develop its signature celadon green.
These kilns allowed for:
Some of the longest dragon kilns stretched over 60 meters, winding up hillsides like serpents - hence the name.
A Global Legacy
By the Yuan Dynasty (1271-1368), Longquan celadon had become a major export commodity. Archaeological evidence reveals that Longquan ware was shipped throughout Asia, the Middle East, and even East Africa. Pieces have been discovered in shipwrecks, royal tombs, and medieval Islamic cities, often treated as diplomatic gifts or symbols of wealth.
In Japan, Longquan celadon influenced tea ceremony aesthetics. In Korea and Thailand, local potters adopted its techniques. In the Islamic world, it was treasured for its refined form and purity of color, often used for religious and ceremonial purposes.
Decline and Preservation
Following the Ming Dynasty's rise and the increasing dominance of blue-and-white porcelain from Jingdezhen, Longquan's prominence waned. Many kilns fell into disuse, and traditional techniques were gradually forgotten.
However, in recent decades, efforts to revive Longquan celadon have surged. Artisans and scholars have excavated ancient kiln sites, studied Song and Yuan pieces, and re-created historical recipes and firing conditions. Today, Longquan celadon is not only a cultural symbol but a living art - practiced by masters recognized by UNESCO as custodians of intangible heritage.
Celadon Across the World
Longquan celadon was not just admired in China - it became a global icon. Through the Maritime Silk Road, it reached:
Celadon symbolized Chinese craftsmanship, Confucian restraint, Daoist naturalism, and Buddhist serenity. It was both commodity and cultural statement.
Celadon in Museums Today
Today, celadon lives not only in the memory of kiln smoke and clay-streaked hands, but also behind glass - preserved and celebrated in museums across China and around the world. These vessels of jade-green still speak, carrying whispers of dynasties, trade winds, and timeless aesthetics.

Modern Revival and Recognition
Though celadon declined after the Yuan dynasty, the flame never died out. In recent decades, Longquan celadon has seen a major revival. Artisans have returned to ancient techniques while embracing modern innovation.
In 2009, UNESCO recognized Longquan celadon as part of the Representative List of the Intangible Cultural Heritage of Humanity.
Workshops and cultural centers in Longquan, Hangzhou, Suining, and beyond continue the tradition - firing not just clay, but memory.
A Story Shaped by Hands
From mud to masterpiece, from riverbanks to royal courts, from early rice farmers to imperial artisans - the story of celadon is the story of civilization itself.
It reminds us that even the simplest elements - earth, water, fire, and time - can, with care and vision, become something eternal.
In museums, these green-glazed vessels rest behind glass. But they are not silent. They whisper of the Stone Age, of Zhejiang's misty hills, of kilns glowing red in the night, and of hands that never stopped shaping beauty from the earth.
