What is Jian Zhan (Tenmoku)?

Jian Zhan (建盏), also known as Tenmoku, is a type of Chinese tea bowl originating from Jianyang, Fujian Province during the Song Dynasty (960-1279). Each piece is handcrafted and fired at over 1300°C, producing unique crystalline glaze patterns that are never repeated.

Is Jian Zhan the same as Tenmoku?

Jian Zhan is the original Chinese ceramic tradition from Jianyang, while Tenmoku is the Japanese name that became widely used after monks brought these bowls from China to Japan. Many modern buyers use both terms for iron-rich, high-fired tea bowls with crystalline glaze effects.

How are Jian Zhan tea cups made?

Jian Zhan cups are made from iron-rich local clay, hand-shaped on a potter's wheel, then fired in a dragon kiln at 1300-1400°C. The iconic glaze patterns (oil spot, hare's fur, partridge feather) form naturally from iron crystallization during firing.

Why are Jian Zhan cups good for tea?

The iron-rich clay and unique glaze help retain heat longer, soften the water, and enhance tea flavor. The mineral content is said to improve water quality. The thick walls keep tea at optimal drinking temperature.

How to care for Jian Zhan tea cups?

Rinse with hot water before and after each use. Avoid soap or detergents. Over time, tea oils will create a beautiful patina. After use, let it air dry completely. Handle with care as each piece is a unique work of art.

Are Jian Zhan cups dishwasher safe?

No. Handmade Jian Zhan cups should always be hand-washed with hot water only. Dishwashers and harsh detergents can damage the delicate crystalline glaze surface.
