# Longquan Celadon: A Guide to Its Types, Glaze & History
There is a Chinese phrase for a glaze at its best — 雨过天青, "the blue of the sky after rain." Longquan celadon is the ceramic that spent over 1,700 years chasing that single, impossible green. Fired in the hills of southern Zhejiang, it became the measure of Song-dynasty taste. In 2018 a Southern Song mallet-shaped kinuta vase sold at Christie's in Hong Kong for HKD 42.85 million. This is Jihe Objects' field guide to the ware — what it is and how to read the real thing. Our Chinese traditional crafts hub gathers every guide in the cluster, and our essay on Chinese traditional crafts for modern living shows how these objects return to daily use.
Key Takeaways
- Longquan celadon is a green-glazed stoneware from Longquan, Zhejiang, with a 1,700-year firing tradition reaching its Southern Song peak.
- Its glazes — powder-blue (fenqing 粉青) and plum-green (meiziqing 梅子青) — come from reduction firing at 1,180–1,310°C in wood-fired dragon kilns.
- The Ge/Di (哥窑/弟窑) legend splits the tradition into crackled and uncrackled lines.
- Authentic pieces show an even blue-green glaze, an unglazed "iron-foot" (朱砂底), and almost no painted decoration.
- The craft entered China's national intangible heritage list in 2006 and UNESCO's Representative List in 2009 — the first and only ceramic craft so honoured.
What Is Longquan Celadon
Longquan celadon is a high-fired, green-glazed stoneware made in Longquan, Zhejiang, China. Prized since the Southern Song dynasty, it is famed for its jade-like powder-blue (fenqing 粉青) and plum-green (meiziqing 梅子青) glazes and its near-total absence of painted decoration.
Dozens of kiln sites climb the valleys of southwestern Zhejiang. What unites them is the glaze — a translucent, iron-tinted green between jade and still water. In the West, Chinese celadon took its name not from China but from a French novel.
Celadon, greenware, and the French "Céladon" name
The term entered European use in the 17th century through Honoré d'Urfé's L'Astrée, whose hero Céladon dressed in pale grey-green. When Chinese green ware first reached France in quantity, the color reminded courtiers of his costume, and for two centuries "celadon" meant any East Asian green-glazed ceramic.
That looseness matters. Celadon porcelain is a broad category; Longquan ware is specific — it names a geography and a lineage. When collectors search for Song dynasty celadon, they usually mean the Song and Yuan output of the Longquan kilns, the green that set the measure for everyone after it.
Why Longquan stands apart from other celadon wares
Yue ware, to the north, made green ware first and taught Longquan its grammar. But Longquan pushed the glaze thicker and cooler — where early Yue tends toward olive, mature Longquan reaches a clear, slightly blue green that stays restrained.
What makes Longquan celadon stand apart is chemistry and patience. Potters built the glaze in multiple dips so it pooled deep in carved lines, then fired in reduction to pull the iron toward blue. That interior glow tells Longquan from the paler greens of other kilns.
A Brief History
Most accounts trace Longquan as a rise, a fall, and a return — and the bones hold.
From Yue-ware roots to the Southern Song peak
Longquan's kilns opened around the early 10th century on the Yue-ware tradition of nearby Shangyu and Shaoxing. The early wares were competent but unremarkable.
Everything changed when the Song court moved south to Hangzhou in 1127; the imperial taste for refined Ru and Guan wares relocated, and Zhejiang's kilns rushed to meet it. By the Southern Song (1127–1279), Longquan had developed its defining glazes: the soft, bluish fenqing and the deeper, almost emerald meiziqing. The best pieces travelled to court and ports.
The Ge (elder brother) and Di (younger brother) kiln legend
A Ming-era text tells of two brothers, Zhang Shengyi (章生一) and Zhang Shenger (章生二), who ran neighbouring kilns during the Song. The elder, Ge (哥, "elder brother"), produced wares with a deliberately crackled glaze; the younger, Di (弟, "younger brother"), made uncrackled wares of flawless, glassy green.
The legend fixes a real distinction. Ge ware (哥窑) has a darker body and a thick, fractured glaze stained to show two tones — fine golden lines over coarser dark ones, the famous 金丝铁线. Di ware (弟窑), the line closest to what we show as Longquan celadon today, kept a pale body and a smooth, uncrackled fenqing or meiziqing glaze. Scholars question whether the brothers were historical, but the split they represent is genuine.
Powder-blue (fenqing 粉青) and plum-green (meiziqing 梅子青) glazes
These two names are the heart of Longquan's reputation. Fenqing is the softer, misted grey green; meiziqing is the brighter, more saturated green with a faint blue cast, both from a feldspathic glaze with a little iron fired in reduction so the iron reads ferrous rather than ferric.
Court taste of the Southern Song prized fenqing most, but meiziqing is what modern eyes find most seductive. Neither is "better"; they are two answers to the same question — what does that quiet green want to be?
Export powerhouse along the Maritime Silk Road
Longquan was never only a court ware. From the Southern Song through the Yuan and into the early Ming it was among the world's most exported ceramics, carried from Quanzhou to Japan, Southeast Asia, the Middle East, and East Africa.
The clearest evidence is the Sinan shipwreck, a Yuan vessel that sank in 1323 and was raised in the 1970s. Of roughly 17,000 ceramics recovered, more than half were Longquan celadon — whole crates of everyday bowls, proof that by the 14th century Longquan ware was a global commodity. For comparable pieces, the Longquan celadon in The Met collection offers an open-access reference.
How It's Made
Understanding Longquan celadon means understanding the fire — its look is not painted on but coaxed from clay, glaze, and heat in a sequence barely changed in a millennium.
Clay, zijin clay (紫金土) and the glaze recipe
Longquan celadon begins with local porcelain stone, but its defining ingredient is zijin tu (紫金土), an iron-rich clay from the Longquan hills that gives the stoneware its warmth and, after firing, a reddish tone at the unglazed foot. The glaze is a simple feldspathic recipe — weathered stone, plant ash, a little iron-bearing mineral — applied in multiple dips.
What makes the glaze special is thickness and low iron (under two percent) that keeps the color green rather than brown. Potters layer three or four coats; carved lotus petals let the thick glaze pool darker in the recesses, a shadow play needing no paint.
The dragon kiln (龙窑) and wood firing at 1,180–1,310°C
Longquan fired in longyao, "dragon kilns": tall, narrow tunnels up a hillside, sometimes thirty or forty metres long, wood-fed along the lower side so one firing reaches a range of temperatures.
The best blue-greens appear in the upper window — above roughly 1,250°C the iron pulls toward the cool, blue end of green. Wood firing sustains reduction: starving the chamber of oxygen forces the iron to bond as ferrous oxide, the state that gives celadon porcelain its color. Active stoking runs 20 to 30-plus hours; the full sequence can pass 70 hours, by potters' accounts.
Why crazing happens — the crackle (开片) mechanism
The crackle that defines one branch of Longquan celadon — Ge ware — is not a naive defect but a controlled failure. Glaze and body shrink at different rates as they cool, and the glassy glaze eventually splits. On most ceramics that is a flaw; Longquan's Ge line made it a feature.
Skilled potters encouraged crazing and deepened it, staining the cracks with ink or tea so the fine lines darkened into the 金丝铁线 pattern. On Di-type wares the aim was the opposite — a glaze tuned and fired so the surface stayed whole. Either way, the crackle records the moment the piece cooled.
Craft cousins: when celadon meets Chinese lacquerware
Longquan is not the only Chinese craft to find beauty in a break. Chinese lacquerware has its own tradition of repair through kintsugi-like methods, and the aesthetic logic overlaps. Where the lacquer artist fills a chip with gold-laced urushi, the celadon potter lets the glaze fracture into a deliberate map. Both treat the object as alive across time rather than finished at the kiln.
How to Identify & Appreciate Longquan Celadon
For a buyer, the practical question is how to identify authentic Longquan celadon. The answer lives in three places — the glaze, the foot, and the crackle.
5 signs of authentic Longquan celadon:
- An even, translucent blue-green glaze that leans cool — and is almost never painted
- An unglazed foot that fires to a reddish "iron-foot" (朱砂底)
- Fine, regular crazing on Ge-type wares; a clean, glassy surface on Di-type
- A substantial stoneware body that gives a clear, slightly resonant ring when tapped
- No tidy reign marks on early pieces — provenance beats signature
Reading the glaze colour
Start with the surface. Genuine Longquan shows an even, slightly translucent green that leans blue rather than yellow. Fenqing reads pale and misted; meiziqing reads deeper and cooler. Both have a soft sheen, never a hard factory gloss.
Watch for fakes: uneven color, a yellow or brown cast from too much iron, or a flat, painted-on green all argue against Longquan. The ware was almost never painted — its point was the single, quiet glaze — and a piece covered in overglaze enamel is, by definition, not celadon in the Longquan sense.
The foot and the "iron-foot" (朱砂底) tell
Turn the piece over. Authentic Longquan usually leaves the foot ring unglazed, and because the body carries iron-rich zijin tu, that exposed clay fires to a reddish-brown — the "iron-foot," or 朱砂底. The contrast between cool green above and warm brown beneath is one of the ware's signatures.
A foot fully glazed over, or one that is pure white, should raise a question — Longquan bodies are warmer and greyer than bright white porcelain. The iron-foot is not universal, but its absence on a piece claimed to be early Longquan is a reason to look harder.
Crackle patterns and what they mean
If the piece is Ge-type, expect crazing that means something: the 金丝铁线 pattern marks deliberate, stained crackle, structured rather than random. On Di-type wares the glaze should be clean and uncrackled, with a glassy evenness.
Random, coarse cracking across a "plain" green bowl often signals a later imitation or damage dressed as style. The eye learns true Ge crackle's regularity faster than words can.
Forms, marks, and what authentic Longquan doesn't do
A few rules close the loop. Longquan bodies are substantial and, tapped, give a clear, slightly resonant ring — stoneware, not thin earthenware. Scholar-object forms (brush pots, water droppers, incense boxes) and generous bowls and plates are typical; maker's seals exist but are late and inconsistent, and an early piece "signed" with a tidy reign mark is likely a later tribute.
What authentic Longquan does not do: it carries no painted figural decoration, shouts no color, and pretends to be no porcelain it is not. Restraint is the whole argument — trust the restrained piece over the loud one.
Iconic Forms
Certain shapes carry the reputation of Longquan celadon as a whole. Knowing them helps you recognize the ware even before you read the glaze.
The mallet-shaped 'kinuta' vase
The kinuta — a tall, flat-shouldered vase named for the Japanese fulling block it resembles — is the form collectors chase. The benchmark is Lot 8007 from Christie's Hong Kong evening sale "Beyond Compare" on 26 November 2018: a Southern Song Longquan celadon mallet-shaped kinuta vase, 23.4 cm high, which sold for HKD 42,850,000. The result confirmed that a perfect Southern Song meiziqing piece ranks among the world's most valued ceramics. Review the record through a Southern Song Longquan celadon 'kinuta' vase that sold for HKD 42.85 million at Christie's. For the market today, buy Longquan celadon usually begins with smaller, later, or studio pieces rather than auction-grade Song originals.
Bowls, plates and the scholar's objects
The everyday Longquan was humble: stacked bowls with a lobed rim, flat dishes, and scholar's desk wares. Among the most admired is the cong-shaped vase (琮式瓶), a slender bottle with squared, fluted sides echoing the ancient jade cong.
Incense burners and tea wares
Longquan also made objects for use rather than display: tripod incense burners (鼎式炉) with their quiet glaze suited the literati incense rite, and tea bowls answered the Song passion for tea. Our guides to celadon incense burners and the tea ritual show how the same glaze works in a modern hand.
Living Makers & Continuity
A craft that stopped being made would be a relic. Longquan did not stop.
UNESCO recognition (2009) and the living tradition
The firing tradition of Longquan celadon entered China's first batch of national intangible cultural heritage in 2006 (catalogue number Ⅷ-9). Three years later, in September 2009, it joined the UNESCO Representative List of the Intangible Cultural Heritage of Humanity. No other ceramic craft has earned that place on the list. The recognition names a living practice — the knowledge of clay, glaze, and kiln passed from hand to hand.
For a buyer the practical upshot is this: "intangible heritage" protects the making. A new piece fired by a trained Longquan potter carries the same lineage as a Yuan bowl. The value is in the continuity, not only the age.
How a 1,700-year craft survives in modern Longquan
Longquan today is a working ceramics town where Longquan celadon is still made, not a heritage park. Kilns still climb its hills, and the old shifu and tudi system — master and apprentice — moves the skill along. The pressure is real: mass-produced green tableware competes on price, and the long training a true Longquan glaze demands is hard to fund. What keeps the line alive is the recognition above — it makes a master's livelihood visible. The 1,700-year count is not a museum number; it is a payroll.
Shared revival: Ming furniture joinery and other heritage crafts
Longquan is not reviving alone. The same national interest in living craft has lifted Ming furniture joinery, bamboo weaving, and lacquerware alongside it. Both Longquan and Ming joinery rest on the same two legs: a regional material — clay in one case, timber in the other — and a master-to-apprentice line that no manual can replace.

Collecting, Caring for & Living with Longquan Celadon
Owning Longquan celadon is easier than the auction prices suggest — and keeping it is mostly common sense.
Building a collection without overspending
The HKD 42.85m kinuta is the headline of the Longquan celadon market, not its entry point. Most collectors begin with later or studio pieces — a revival bowl, a potter's tea cup, a small incense box — that carry the same glaze logic at a fraction of the cost. Buy from named makers or reputable dealers, ask for provenance, and learn the foot and glaze rules before spending serious money.
Caring for celadon
Your Longquan celadon is tougher than it looks, with two enemies: sudden heat and hard knocks. Avoid a cold piece under a scalding tap, and never use a dishwasher. Hand-wash in warm water, dry before stacking, and keep harder-edged items off the glaze. Treat it this way and a Longquan piece will outlast you by generations.
Celadon as tea ware — a Chinese tea setup
The most natural home for Longquan celadon is the tea table. A meiziqing cup warms with a living unevenness no factory wall has, and the glaze throws the tea's color back in a way porcelain flattens. Our scene guide to a Chinese tea setup lays out the objects step by step — start with a single cup and a small tray. For the fuller picture, celadon for the tea table connects the ware to the slower morning it was made for.
Celadon as flower vessels
A lone branch in a pale Longquan celadon vase is one of the oldest Chinese arrangements. The cooler the glaze, the more it frames a stem as a line. Match a tall fenqing bottle to a single vertical branch; a low lobed bowl suits a wider spread. Our notes on celadon vases for flowers cover the forms; change the stem with the season.
Bringing Celadon into Modern Life
At 幾禾集物 we hold a simple line about Longquan celadon and objects like these: use them. A Song bowl behind glass is safe and silent; the same bowl holding water and a single stem is alive, and that conviction runs through our essay on Chinese traditional crafts for modern living.
If the glaze has pulled at you, the next step is practical. Browse our heritage craft collection to see finished Longquan pieces ready for the table, or return to meet the makers whose names sit on the base. The study ends; the use begins.
Frequently Asked Questions
Is Longquan celadon on the UNESCO intangible heritage list?
Yes. The traditional firing technology of Longquan celadon was inscribed on UNESCO's Representative List of the Intangible Cultural Heritage of Humanity in 2009, making it the first and only ceramic craft on that list. It had entered China's national intangible heritage list in 2006.
What is the difference between Ge (elder brother) and Di (younger brother) ware?
Ge ware (哥窑) is the "elder brother" line: a darker body and a thick, deliberately crackled glaze showing golden-thread and dark-iron (金丝铁线) crazing. Di ware (弟窑) is the "younger brother" line: a paler body with a smooth, uncrackled glaze in powder-blue (粉青) and plum-green (梅子青). The split comes from a Ming-era legend of two brothers, Zhang Shengyi and Zhang Shenger.
How can you tell if Longquan celadon is authentic?
Look for an even, lustrous blue-green glaze (Longquan is almost never painted), an unglazed foot that fires reddish, fine intentional crazing if it is Ge-type, a substantial resonant body, and maker marks or provenance. Fakes often show uneven color, painted decoration, or a fully glazed-over foot.
Is Longquan celadon safe for everyday use (tea, food)?
Yes. Traditional and modern Longquan glazes are lead- and cadmium-free and food-safe. Care tips: avoid sudden temperature shock, hand-wash in warm water, and do not stack hard-edged items against the glaze.
Conclusion
Longquan celadon is one craft with many faces: a legend of two brothers, a green that took 1,700 years to perfect, a kiln climbed by fire, a foot that tells the truth about the clay. Its fenqing and meiziqing glazes remain the restrained standard of Chinese green ware, and named national heritage in 2006 and UNESCO heritage in 2009, the craft keeps its firing alive.
