History & Development
Xu Chaoyun carries the Longquan celadon tradition from Zhejiang's kiln district, where green-glazed stoneware has fired continuously since the Song dynasty. The glaze's jade-like depth results from multiple applications and precise reduction firing, techniques nearly lost when kilns dwindled in the early twentieth century.
State re-establishment of the Longquan kilns in the 1950s relied on surviving masters who reverse-engineered historical glaze formulas through hundreds of test firings. Xu Chaoyun continues that experimental discipline, combining archaeometric study of shard chemistry with hands-on kiln management that UNESCO recognized in 2009 under celadon craftsmanship.
Cultural Traditions
-
Layered Glazing
Applying three to four glaze coats builds optical depth as light refracts through suspended iron particles, producing the plum-green and seaweed-green tones prized since the Southern Song.
-
Crackle Control
Deliberate crackle networks emerge from thermal contraction differences between body and glaze; masters tune cooling curves to guide the pattern rather than leaving it random.
-
Dragon Kiln Firing
Wood-fired climbing kilns demand continuous stoking judgment across dozens of hours, reading flame color through spy holes to steer reduction atmosphere.
Common Questions
What makes Longquan celadon valuable compared to other ceramics?
Longquan celadon achieves jade imitation through chemistry alone, and historical export shards found from Japan to East Africa testify to a millennium of demand.
How are new glazes developed today?
Masters run comparative firings varying iron content and kiln atmosphere, documenting each result against Song-era reference shards in a continuing research practice.
