Duanni and Zini are two common Yixing clay records, but they should not be compared as if one is always better. They describe catalog categories with variation inside each group. A useful comparison looks at color, shape, capacity, photos and the exact product evidence.
Color and appearance
Zini is often associated with purple or dark clay records. Duanni can include lighter, yellow, beige, greenish or mixed-looking records depending on the exact listing. These are broad observations, not fixed rules. Always inspect the actual photos.
Brewing use
Some buyers use clay charts to assign Duanni or Zini to specific teas. That can be a starting idea, but it is not proof. The pot’s capacity, opening, pour, heat behavior and your brewing method have direct practical impact. Use your tea routine to choose size first, then compare clay.
Product-page evidence
For either clay, check the full gallery, stated capacity, dimensions, craft record and maker attribution. If a listing promises a dramatic effect or rarity, ask what supports that claim. A clay name does not independently prove origin, age or value.

Which should a beginner choose?
A beginner should choose the pot that fits their cups, tea leaves and hand. If you prefer lighter surfaces and varied recorded colors, Duanni may attract you. If you prefer classic darker purple records, Zini may be easier to shortlist. Neither label removes the need to check size and photos.
Fast checklist

- Does the capacity match one person, two people or a group?
- Can you see enough spout, lid and interior detail?
- Is the craft record specific and cautious?
- Does the price fit the evidence?
