Celadon
Celadon is a ceramic glaze known for its characteristic translucent green color, obtained by adding small amounts of iron oxide to the glaze. This distinctive color is produced during firing in a reducing atmosphere, where the iron oxide changes from its oxidized state (Fe³⁺) to its reduced state (Fe²⁺), generating green hues that can range from soft and grayish to intense, depending on the composition of the glaze, the thickness of the applied layer, and kiln conditions.
Celadon is typically applied on stoneware or porcelain ceramic bodies, as these materials allow the glaze to acquire its characteristic translucent appearance. In addition to its unique aesthetics, celadon highlights carved or engraved details on the surface of the piece, as the translucent glaze builds up on the reliefs and creates subtle contrasts.
Although historically associated with green, celadon can vary in hue depending on factors such as the chemical composition of the glaze, kiln temperature and firing atmosphere. These variations include blues, grays and even shades close to amber, depending on the specific process conditions.
Today, celadon remains a popular technique in contemporary ceramics, both artisanal and industrial, appreciated for its combination of simplicity, elegance and visual depth.Interesting Fact
Celadon originated in China during the Song dynasty (960-1279 AD), and was developed to imitate jade, a precious stone deeply prized in Chinese culture. It was considered one of the most valued glazes, and pieces from that era are still highly prized by collectors around the world.Helpful Tip
If you want to achieve a true celadon finish, be sure to fire the pieces in a kiln with a reducing atmosphere to obtain the characteristic soft, translucent green tones.
