What Is Celadon?
Celadon is a type of high-fired ceramic known for its translucent glaze in pale green to bluish-green tones, resembling jade. The glaze is typically applied over stoneware or porcelain and is admired for its subtlety and elegance. The term “celadon” was popularized in Europe, inspired by a literary character who wore pale green robes.
Origins and History
Celadon originated in ancient China during the Shang and Zhou dynasties as proto-celadon. True celadon emerged during the Eastern Han dynasty (25–220 CE) and reached peak refinement during the Song dynasty. The Longquan kilns in Zhejiang became famous for their rich jade-like glaze, while Korean artisans developed their own version during the Goryeo dynasty using inlay techniques known as sanggam.
Celadon Characteristics
- Color: Soft green to blue-green in most electric-fired pieces. Wood-fired celadon can show more variation, including olive green, gray-green, seafoam, and even bluish or smoky tones, depending on flame path, ash, and kiln placement.
- Glaze: Smooth, glassy, and often lightly crackled (crazed); in wood-fired pieces, glaze may pool, drip, or show subtle ash textures.
- Decoration: Carving, incising, or inlay; patterns are often subtle and rely on the glaze to reveal texture.
- Material: Usually stoneware or porcelain body, fired at high temperatures (~1200–1300°C).
Celadon Across Cultures
China (Longquan & Yue Ware)
Chinese celadon from Longquan kilns is known for its thick glaze, sea-green color, and carved floral motifs. These were widely exported during the Song and Yuan dynasties.
Korea (Goryeo Celadon)
Goryeo celadon features a brighter green tone and unique inlay designs. These pieces often included lotus flowers, cranes, or cloud motifs in white or black slip beneath the glaze.
Wood-Fired Celadon
Wood-fired celadon is fired in traditional wood-burning kilns, such as long dragon kilns. The firing process adds unique natural effects due to wood ash and flame movement.
- Reduction Atmosphere: Limited oxygen enhances iron oxide, deepening green hues.
- Ash Effects: Melting ash creates natural speckles, drips, or glaze flows.
- Color Variation: Pieces may shift in color from green to olive, seafoam, gray-green, or bluish tones depending on position in the kiln.
| Feature | Wood-Fired | Electric Kiln |
|---|---|---|
| Atmosphere | Natural reduction with ash effects | Controlled reduction or neutral |
| Surface | Varied with natural textures | Smooth and consistent |
| Color | Olive, seafoam, gray-green, smoky blue | Uniform soft green or blue-green |
| Scale | Small-batch, artisanal | Mass-produced or repeatable |
Linglong Porcelain
Linglong (玲珑) porcelain, also known as “openwork” or “rice grain porcelain,” features tiny translucent windows carved into the ceramic and filled with clear glaze. When combined with celadon glaze, it produces elegant, light-enhancing effects.
- Technique: Hollow patterns carved before glazing and firing.
- Appearance: Glows when held to the light; often used in teaware and tableware.
- Origin: Jingdezhen, popular during Ming and Qing dynasties.
