I have many Chinese tea cups and some tea bowls and a few Japanese cups. The Chinese range from 400 ml filled to the rim to those very small ones of 15 ml which I have for their beauty and not to drink from.
Certain cups I love to use with certain teas and one tea bowl of 200 ml filled to the rim of very thin porcelain I use for silver needle and good pu-erh tea. I can hold this cup with both hands and no other cup gives back the aroma like this one.
I had 3 pieces, which were the only once in the store. Unfortunately I dropped one which shattered into a zillion pieces.
I searched countless websites selling tea cups, and yes they are mostly in the small range, in the hope that I will find such a tea bowl since I live in constant fear breaking another one of these cups. So far no luck. If there are larger cups offered they are more like bakers or made of clay like my 400 ml bowl.
I am sure going to China one can find them since such larger cone shaped (flared?) cups have been made since ancient times.
