All I used to have was a simple infuser but I do have some teaware now.
They use a lot of crap in the chinese style tea ceremony, but yeah, he could've done it all with the gaiwan that you see in the corner, didn't even need a cup. I have one in borosilicate glass (I like to see the leaves).
I also have a lidless teapot (I like to see the leaves) which is slightly different from the traditional kyusu.
I'd like to get a brewing tray but haven't really looked/found one that I like yet.
