Yixing teapot 宜兴紫砂壶

Editors · October 23, 2026 · 5 min read

An unglazed teapot of zisha clay, mined near the city of Yixing in Jiangsu province. Its porous walls hold heat, and a film of tea slowly builds up inside, so each pot is kept for one type of tea.

Yixing (宜兴) lies in Jiangsu province, on the western shore of Lake Tai. The hills around it yield zisha clay (紫砂, “purple sand”), and teapots have been made from it since the 16th century, under the Ming dynasty. The zisha teapot arrived with the habit of steeping whole leaf: under the Ming, powdered tea fell out of use, and people needed a vessel the leaf could open up in. Over five centuries the Yixing teapot became China's main clay brewing vessel, and the word “Yixing” turned into a label stamped on almost anything.

Zisha clay

Zisha is the name for several clays from the same deposits. Three turn up most often:

• zini (紫泥), purple-brown, the most widespread;
• zhuni (朱泥), red and rich in iron: it shrinks a lot in firing, and the walls come out thin and dense;
• duanni (段泥), pale, from golden to gray-green, often speckled.

Potters fire the teapots unglazed at 1100–1200 °C, which leaves the body dense enough to hold water but with fine pores. The walls give up heat slowly, and the oils and aromatic compounds of the liquor gradually settle into the clay. Brew the same tea side by side in a gaiwan and in a seasoned Yixing pot: the liquor from the pot usually comes out softer, its sharp notes muted.

Thin-walled zhuni heats up faster and absorbs less, and it is a favorite for aromatic oolongs. Zini is thicker and more porous; it suits teas that need sustained heat, such as dark Liu Bao.

One pot, one type of tea

Clay soaks up the scent of everything brewed in it, and after a year of daily sessions even plain boiling water poured into the empty pot smells of tea. Hence the main rule: each pot gets its own type of tea, ideally a single tea. Brew floral Tie Guan Yin in a pot that has spent a year with Da Hong Pao, and its aroma drowns in roasted notes. Smoky Zheng Shan Xiao Zhong leaves a pine scent that lingers in the clay for a long time, so it gets a pot of its own.

People keep Yixing pots for roasted oolongs, black tea and pu-erh, with separate pots for sheng and shu. Green and white teas rarely go into clay: thick walls hold heat for a long time and stew the tender leaf, so these teas are brewed in a gaiwan or glass.

Care

Before its first session a new pot is prepared, a step called kai hu. The simplest way is to rinse the pot inside and out with hot water, fill it with boiling water, let it cool, and repeat two or three times. After that, brew the tea the pot is meant for and pour away the first infusions.

After each session, take the leaf out with a bamboo scoop, rinse the pot with boiling water and let it dry with the lid off. Wipe the outside with a soft cloth; many people also pour hot water over it during the session. Over the years the clay takes on an even matte sheen, called baojiang (包浆) in Chinese. With hard water, pouring leaves a mineral ring on the lid (more on this in teaware care).

How to choose

For gongfu cha, you want a 100–200 ml pot; 80–120 ml is enough for one person. Then test the pot in use rather than judging the clay alone.

The lid should sit tight, with no play. Fill the pot with water and tilt it while covering the hole in the lid with a finger: with a well-fitted lid the stream stops. The spout should pour an even stream that does not break up or splash, and the pot should not drip afterwards. The empty pot sits comfortably in the hand, and the handle does not outweigh the spout.

Fakes

Genuine zisha is scarce, demand for Yixing teapots is huge, and the market is full of teaware that has nothing to do with Yixing. You will come across pots of ordinary clay tinted with dyes, blends with a small share of zisha, and slip-cast pots made from liquefied clay.

Warning signs:

• a factory-mug price on a “handmade” pot;
• gloss on a new pot: fresh zisha is matte, real shine takes years, and shine on a pot in a shop comes from wax or polish;
• a chemical, varnish or paint smell after boiling water;
• a loud, bright color unnatural for clay;
• glaze inside, which zisha never has;
• water that turns colored when the pot is held in boiling water.

No single sign proves anything on its own. It is safer to buy from a seller who names the clay and the method: fully handmade (全手工), half-handmade in a mold (半手工) or slip-cast. And who lets you test the pot with boiling water before you pay.
