Tazze Jianzhan

Amidst the vast constellation of Chinese ceramic culture, Jianzhan stands as the pinnacle of black porcelain artistry, distinguished by its profoundly dark glaze and naturally formed patterns.

Born in Jianyang area of Fujian, and historically known as ‘Jian Kiln Jianzhan,’ it ranks among the Eight Great Ceramics of the Song Dynasty, bearing witness to millennia of evolution in Chinese ceramic craftsmanship. Emperor Huizong of Song, in his Treatise on Tea, declared: ‘The finest bowls are those of a deep, lustrous black, adorned with streaks of jade-like flecks.’

The tea world hails it as ‘the vessel born for tea,’ while the ceramics sphere extols it as ‘the art of earth and fire's most demanding union.’ 

Jianzhan glazes are valued for their artistic unpredictability: the iconic patterns on the surface form naturally in the kiln for the interaction between the iron in the clay, the iron in the glaze and the high-temperature.

During firing, the iron in the glaze melts and moves within the surface layer. As the kiln cools, the iron crystallizes and separates into fantastical patterns: yao bian "starry" glazes shimmer like hidden celestial rivers, youdi "oil-drop" glazes resemble emerald-studded pearls, tuhao "rabbit-fur" glazes evoke autumn frost on branches, while zhuge ban "partridge-speckled" glazes mimic feathered clouds over mountains.

Because the glaze is rich in iron and applied relatively thickly, it also enhances depth and visual texture. When light hits the surface, it interacts with the crystalline structures, giving the bowl a sense of movement and dimensionality. You can see a microspoce enlargement of a Jinzhan surface realized by our artist and scholar Zhan Yanfu.

In 2019, his works featured at the Global Diplomats' Chinese Culture Night, and were subsequently selected for three consecutive years as event gifts presented to ambassadors from 162 nations.

Master Zhan Yanfu's work has also been acquired by museums: in 2020 his Golden Thread Rabbit-Hair Bowl was permanently acquired by Min-Tai Yuan Museum; and in 2021 his ‘Wood-fired Rabbit-Hair Splayed-rim Bowl’ was acquired by the National Art Museum of China.

铁瓷墨韵 "Iron porcelain, ink charm" is a sentence often carved on his bowls, engraved by artists and reknowned calligraphers of modern times.
