Can I use the same Yixing teapot to brew all kinds of teas?
Yes, you can, but not really. First, the Yixing Zisha teapot can absorb the tea juice that result amazing that is you can get the tea aroma when you only pour water into the teapot without tea. So you’d better use different teapot to brew different tea if you want to get that teawater without tea; Second, black tea is full oxidation and green tea is oxidation-free tea, so you can choose tall teapot with narrow mouth to brew black tea and choose short teapot with wide mouth for brewing green tea in order to protect it from braised bad. For Oolong tea, you can choose middle height teapot, Chinese call this kind of teapot as MengChen teapot.
