Opother,

I like your idea of separate teapots, but were you planning to have a yixing
for each? Or pots of some other material?

I believe yixings are recommended for oolongs, and sometimes blacks too,
because they are amenable to high-temp brewing and hold heat well. You may
want to consider porcelain or ceramic for green teas, though, as these are more
delicate and take lower temperatures. And something about the elegance of a
fine gaiwan or teapot, I think, complements the aesthetics of a beautiful green
tea.

But this is not to say you can't use a yixing pot for green tea as well. You
can certainly do what you like!

By the way, my "yixing" pot came from Ten Ren in NYC. I guess I liked the
particular pot, though I saw a few others in stores nearby. It seems to work
fine, and has developed a nice tea-aroma of its own. I have been brewing both
lightly and heavily oxidized oolongs in it; some might prefer a separate one
for each type. Then too, some smaller yixings are so inexpensive that it would
be easy to collect a few.
