Tetsubin

Surprisingly no. They are in fact used to brew in. Many (unglazed even) testsubin come with a metal strainer for tea. Tetsubin should not be used on a stovetop really though. You have to remove the tea quickly once finished and always rinse it out well and dry it completely so it does not rust. They are a pain, and do not offer any benefits and if anything add to the stress of tea time for me.

However, they are used for water only mainly in modern Japanese tea ceremony so that may be where you were coming from. But originally and still they were used for both purposes. Like I said almost more often they were used secondarily for tea because the water was already boiling for heat/humidity so either some leaves were thrown into the pot or the water was used for making tea. I know a few Japanese friends whose family members still use unglazed tetsubin with the strainers for their daily tea, and many vendors quite clearly will tell you the proper way to use your tetsubin is for brewing tea not for boiling water on the stovetop.

Hell, I know one old Chinese man who boils water in his yixing on a gas stove directly and then adds in his tea... who am I to argue? The pot looks really cool from the fire/tea on the outside too, so nothing is stopping you from using a tetsubin on the stove... and it is much more sturdy than Yixing so go for it if you want. I'm not aware of any secret tetsubin police ;)

I wouldn't use a glazed one; when the glaze chips off, it might wind up in my gullet. I do have a big one that sits on the wood stove in winter; I rarely pour from it, but it's nice to know that hot water's always to hand.

On the latter point: I wonder if, with regular brewing use, a coherent organic film might form and passivate the iron surface? This certainly happens with other cast-iron cookware, and is why a seasoned pot or pan shouldn't be scrubbed down to clean metal. It would be more likely if the pot used for brewing is also used for boiling, hence exposed to direct heat that would enhance polymerization and bonding of the carbonaceous film to the cast iron.

Exactly, that is why they highly prize the mineral/misc. deposits that build up. They believe that the minerals are good for you and that the buildup breaks down a bit and adds the minerals to the brew... me, I don't quite see it in the same positive light. Although just as you said with other cast iron cookware once "seasoned" it does most likely seal up for the most part. I've seen some rough looking tetsubin, and I just can't put that together in my mind or stomach with a beautiful and delicate fresh green no matter how I try. Decoration and above fires fit the bill for me.

Don't know by reading or experiment, but it would almost have to: both as a "core" for multidentate binding by several polyphenols or other ligands, and as a redox catalyst to enhance the further polymerization and cross-linking of the goo.

Goo? That sounds like the scum I remember in the tea I brewed with the iron-rich on the southern fringes of Calcutta. It didn't just look bad, it *tasted* bad.

In the traditional Japanese tea ceremony an iron kettle is deployed over a charcoal fire. What is the Japanese word for this kettle? And what exactly is the English translation for the Japanese word, tetsubin? Water heating kettle came first, glaze lined tea brewing iron pot came second. No number of detailed facts are going to change my mind. I would never allow myself to be swayed by the facts. Michael

If you don't want to give business to Microsoft (which I can understand), consider installing OpenOffice 2.0. This will give you Calc, their Excel replacement.

Just to test, I threw some random Cyrillic characters into an Excel spreadsheet (I don't have Chinese installed), and then opened the file in Calc. It showed exactly what it was supposed to show.

And, since it's free, you don't have to regret spending a lot of money on a piece of software you rarely use.

Now, if it's a drive-space issue, i.e. you're running out of it, this won't help.

Note: Some modern tetsubin are made of alloys which claim to not rust, I forgot to mention that before.

kama - kettle

shinnari kama - "true shape" based on the pot belly of the Tanuki (a raccoon-dog) and the original kama, tea kettle, is seen to have this same shape.

Tetsubin/kama can be made for use on one or both types of heat sources, generally ro can be used for both heat sources while many furo are furo-only.

furo - portable hearth/heat source (summer)

ro - hearth (winter)

kama and tetsubin are not interchangable to me personally, but are to just about everyone else. I call the decorative non-used cast iron tea kettles tetsubin, while I refer to the real deal old kettles and those used in tea ceremony kama.

Here's the free OpenOffice website, for anyone who is interested:

"The Japanese Tea Ceremony" is, in fact, a collection of many different versions of ritual. Most of the time, the water is heated in an iron kettle over a fire. The lid is removed, and a bamboo dipper is used to remove the hot water. This is called a kama.

Some versions of powdered tea ritual call for the use of an iron kettle with a spout and a handle, thus eliminating the need for the dipper. The kettle can be heated over a charcoal fire or an electric heater. This is called a tetsubin, literally iron jug/bottle.

There is a book, in English, called _Tetsubin: A Japanese Waterkettle_ by P.L.W. Arts, Groningen [The Netherlands]: Geldermalsen Publications,

1987. This is a detailed academic work. Maybe you can find this by inter-library loan. Paragon Book Gallery in Chicago might also have occasional copies for sale.

Yes, if we are speaking solely about Japanese tea ceremony then this is correct. However, not many modern folks do in Japan or abroad but many still use the tetsubin in their homes and in almost every case I see them actually brewing tea in them not just heating water. These are the new tetsubin that are made of an alloy not supposed to rust and come with the strainer built in that you can buy in home stores and kitchen shops.

This excerpt is taken directly from the Joyce Chen line of Tetsubin sold everywhere:

"While this traditional Asian teapot cries out for green tea, it's such a joy to use that it would be a shame not to put it to work every day. The well designed lid won't fall off even when you're pouring out the very last drops of tea. It comes with a stainless steel infuser so you can remove the leaves after steeping--especially important when you're preparing delicate green teas."

I guess it depends on what kind of tea you drink and how you brew it, I still find completely drying the teapot inside each time to be a bit of a drag when so many other alternatives are out there that also retain heat well. I also have a personal dislike of metal in my tea brewing process, so I'm admittedly biased.

No contradiction at all! I think it's cool, and it is actually how they were used way back in the day over open fires. The patina it has is really amazing. I just cringe at this semi-delicate Yixing that is at least 60 years old (and nicer than even my best yixing that I care for with untold delicacy) being wailed on by high gas flames on a stove burner... it just *seems* wrong, not that it is.
