Wujin (Black Gold)

【The Mystery of Mysteries: The Minimalist Realm of “Wujin”】

After extreme brilliance, things often return to simplicity. This “Wujin” Diancha bowl has no dazzling patterns or gorgeous colors; it presents the oldest, most basic, and hardest-to-perfect pure “Wujin Glaze” (Black Gold Glaze) of Jianzhan. Under the light, the profound black glaze reflects a mirror-like gloss akin to a tranquil lake. A natural bronze ring along the rim (commonly known as “Koubian”) acts like a ray of morning light at the edge of the night, breaking the dullness of pure black. When your fingers glide over the smooth glaze and finally touch the unadorned, reddish-brown body at the bottom, which retains the authentic granular feel of the clay, you will truly feel the creation miracle of “half fire, half clay.”

【What is a “Diancha Bowl”? — Exploring the Origins of Japanese Matcha】

For overseas tea culture enthusiasts, you may be very familiar with the Japanese “Matcha Tea Ceremony,” but do you know where its origins lie? It comes precisely from the “Diancha” (whisking tea) method of the Chinese Song Dynasty (960–1279 AD) 800 years ago. The literati and scholars of that time did not steep whole tea leaves; instead, they ground tea bricks into ultra-fine powder, placed it in a bowl, added water, and rapidly whisked it with a bamboo whisk until a thick layer of pure white foam appeared. To make the white tea foam stand out more, these pure black Jianzhan became the top-tier tea wares of the Song Dynasty. This “Wujin” bowl is designed strictly according to the rituals of Song Dynasty Diancha: the wide 12.5cm opening provides ample stirring space for the bamboo whisk, while the steep 7.8cm deep walls effectively prevent the tea from splashing. Whisking tea in it, the white foam and the deep black walls contrast with each other, forming a picture of ultimate black-and-white ink wash painting.

【Handcrafted Ingenuity and the Experience of a Heavy Vessel】

•  Hand-thrown using premium black porcelain clay. The hefty weight of up to 500g makes the tea bowl as stable as a mountain on the table. When you whisk the tea vigorously, the bowl will not slide easily, providing you with the firmest support.

•  Treated with a special underglaze color technique, the pure black color is perfectly sealed beneath a transparent glaze layer. Not only is the color warm and jade-like, remaining timelessly new, but it also guarantees absolute safety and non-toxicity.

•  The thick and solid black porcelain body boasts excellent heat retention. It keeps the tea at the optimal temperature during the Diancha process, maximizing the aroma and mellow taste of the tea powder.
