Yixing teapots are traditionally used with oolong, black, and puer tea. The teapots absorb and form a patina of tea in the pot after multiple uses. This will eventually develop a coating that retains the color and flavor of the tea. Yixing clay should be rinsed, not washed to maintain this characteristic. A serious tea drinker should use their Yixing teapot for a single variety of tea (ie. oolongs) so the characteristics of that particular tea shine through over time.
