Jian Zhan Tea Cup Process: How is Tenmoku made?

Material Selection & Preparation in Jian Ware Craftsmanship

The foundation of exceptional Jian Ware lies in meticulous material selection and preparation. Both the glaze and clay demand a high iron content, a criterion met by the natural resources of Jianzhou, which consequently became the epicenter for this distinct pottery. During the Song Dynasty, attempts by other regions to replicate the quality of Jianyao’s cups were futile due to the lower iron content in their local ore.

The chosen materials undergo a rigorous process of crushing and sieving to attain a judicious thickness. The resulting clay slurry and glaze are then stored in a controlled environment with regulated humidity and temperature. Today, advancements in technology make the crushing process more efficient, yet the artist's vigilance remains crucial to ensure uniformity and prevent cracking during firing.

Shaping and Firing the Base

Once the clay is prepared, it undergoes kneading to eliminate air and enhance density. Handcrafted on a turning table, tea cups take shape under the skilled hands of the artist. This labor-intensive process, though time-honored, ensures each cup is unique, reflecting the artisan's dedication to preserving the traditional craftsmanship of shaping and firing the base.

Afterwards, a small knife/tool is used to modify and perfect tea cup.

At last, the unglazed tea cup is fired. This process will strengthen the cup and filter out those cups that are fragile.

Tenmoku Glaze & Firing: Crafting Elegance

After the meticulous creation of the base tea cup, the transformative process begins with glazing. The unique Tenmoku glaze is crafted using a blend of natural iron ore and plant ash, meticulously combined to create a harmonious composition.

The complexity of the glazing process lies in the careful selection of different iron ore and plant ash variations. This deliberate choice influences the crystallization patterns that emerge during the high-temperature firing. Achieving the perfect blend poses a challenge, as the raw materials possess inherently unique characteristics. Ceramic artists engage in a nuanced tweaking process to attain the desired result, often opting to procure a surplus of raw materials to minimize the need for frequent adjustments.

Jian Zhan tea cups, exemplifying a characteristic half-glazed appearance, undergo a specific glazing technique. The cups are skillfully dipped into the glaze, leaving the bottom part unglazed. This practice, refined through extensive practice, demands a delicate balance—ensuring the glaze is neither too thin, allowing for proper crystallization during firing, nor too thick, preventing the glaze from adhering excessively to the bottom. The mastery of this artistry lies in the hands of the ceramic artist, who, through dedication and skill, brings forth the elegant fusion of form and glaze in every Jian Zhan tea cup.

Once the glaze is applied, it will be put into an oven and fired at a temperature around 1300ºC (2370ºF). It's said that firing the oven using pinewood offers the best effect.

Precision in Firing: Crafting with Exactitude

The temperature during firing becomes a critical parameter, subject to slight adjustments based on the specific glaze type and the desired crystallization effects envisioned by the artist. This intricate process, akin to an exact science, demands meticulous attention, as a variance of a few degrees can dramatically alter the final outcome. Notably, the art of Jian Zhan involves a delicate dance of temperatures, where nuanced adjustments contribute to the emergence of unique patterns and colors in the crystallization process.

An intriguing facet of this craft lies in the occasional discovery of new patterns and colors, often stemming from unintentional mistakes in glaze blending or variations in oven temperatures. These unplanned occurrences add an element of serendipity to the artistry, unveiling unexpected beauty born from experimentation.

Upon the completion of the firing process, the artist assumes the role of a discerning curator, carefully examining the quality of each individual cup. Cups that bear cracks or imperfections, no matter how minor, are deemed unworthy and respectfully disposed of. This commitment to quality control ensures that only the finest, flawless Jian Zhan tea cups make their way to tea enthusiasts, preserving the legacy of this ancient art form.

The cups that pass the quality inspection will be divided into different grades and sold to tea enthusiasts.
