Yixing vs other unglazed clay pots
Yixing zisha is one clay among several that behave the same way, and it carries a collector market the others do not. For a drinker rather than a collector, that market is the main practical difference, and it is a difference in price rather than in the cup.

What is being compared
Why these get confused
‘Yixing’ is used loosely for any small brown clay pot, including pots made nowhere near Yixing. The behaviour transfers; the name does not.
Point by point
| Aspect | Yixing teapot | Unglazed clay teapot (non-Yixing) |
|---|---|---|
| The clay | Zisha stoneware from Yixing in Jiangsu, with a documented craft tradition going back several centuries. | Jianshui purple pottery from Yunnan, Chaozhou red clay, Japanese Tokoname — each with its own tradition. |
| Porosity and seasoning | Yes. One pot, one tea, and it improves with use. | Yes, to varying degrees. The one-pot-one-tea convention applies equally. |
| Heat behaviour | Holds heat well, which is the functional argument for clay over porcelain. | Different clays hold heat differently — a real functional difference rather than a marketing one. |
| Price | Wide, and driven substantially by maker, provenance and collectability. | A fraction of Yixing for comparable function. |
| Authenticity risk | High. It is among the most imitated categories in tea, and a buyer cannot verify clay by looking. | Lower, largely because there is less incentive to fake it. |
| Care | Hot water only, no detergent, air-dry with the lid off. | Identical. |
| Who should buy which | Someone who wants the object as well as the tea, and knows which tea it will hold. | Someone who wants the clay’s behaviour and would rather spend the difference on leaf. |
The short answer
The seasoning argument applies to any unglazed clay, so the premium on Yixing buys provenance and craft rather than a better cup. That is a legitimate thing to buy; it is worth knowing that it is what you are buying.
