The Abyss of Light: Where the Black Core Meets Iridescent Stars
Born in the legendary kilns of Hongjing, Jianyang, the Black Core Obsidian series captures the explosive moment of stellar creation. Within the 1300°C chaos of the kiln, iron minerals transform into a deep, obsidian abyss that radiates vibrant, prismatic crystals. Recognized as a National Intangible Cultural Heritage, every cup is a unique testament to ‘One Color In, Ten Thousand Out.’
To hold this cup is to hold the spirit of a thousand-year tradition, reimagined as a piece of functional cosmic art.


01 / The "Black Core" Metamorphosis
The unique ‘Black Core’ effect is the result of extreme temperature control, creating a dark, light-absorbing center that makes the surrounding crystals pop with electric intensity. This high-iron mineral glaze provides a substantial weight and a balanced energy to your tea table.
02 / Iridescent Mineral Crystals
Under direct light, the mineral crystals within the glaze reflect a dazzling spectrum of colors. These vibrant, clearly defined patterns are not painted but are spontaneous gifts of the kiln, ensuring that each cup possesses its own distinct, unrepeatable visual rhythm.
03 / Living National
Listed as a National Intangible Cultural Heritage in 2011, the art of Jian-Zhan is a pinnacle of Chinese ceramic history. This cup adheres to the strictest traditional standards, using authentic Jianyang red clay and natural plant ash to create a vessel that is safe for tea and rich in historical soul.
