Jbu2, I'm not sure where you are in the world but antique stores are fun to look in. Etsy also has many nice ceramic pitchers, some are small enough for tea, you can preheat also. I would make sure they are high fired. Here is one shop; http://www.etsy.com/shop/juliapaulpotte ... info_count
Then you can also look at artisans here on teachat; viewforum.php?f=40
The only problem I see is if you are using a ceramic teapot that imparts character to your tea then you probably don't what to mess that up with yet another ceramic from another part of the world. Either stick to one family of ware, go for neutral glass or porcelain to avoid these issues.
