"The Yixing purple clay (Zi Sha) has the characteristics of fast heat
transmission and good heat preservation.
Teapots made by this material are specifically designed to retain the aroma
and flavors of the tea, especially for Oolong Tea, Pu-erh Tea and Black Tea.
It is better to use a certain Yixing Teapot only for one kind of tea
to avoid mixing flavor of different kind of tea.
TeaVivre carefully select high quality Yixing Teapots and
Yixing Tea Sets with reasonable price. Choose a Yixing Teapot for
your teas from different sizes and shapes you like."
I have several Yixing teapots, and absolutely love them! Not only do they make a wonderful cup of tea, but they are beautiful and feel good to hold and to pour from. They truly are a great investment for any tea lover!
