Hi,

I don't want to be cynical, but I'd contest a few of your claims.

- Cast iron is a poor conductor of heat. This means, it doesn't distribute it well. Even heating is not a strength of cast iron. It saves a lot of heat, that is true.

- Cast iron tea pots are usually glazed. No iron will be released in that case.

I have the model of tetsubin shown in the picture. It comes in 2 versions. One is enameled on the inside and the other is not. Cast iron is a much better conductor of heat than ceramic, glass or porcelain, so ming's statement is accurate. Having said that, I don't consider even heating to be particularly relevant when making tea.

This is a tetsubin, which is an iron kettle for heating water. It is not technically a teapot but can be used as such if you take it off the heat before adding the tea. The fact it conducts heat quite well means it can be used on a stove to heat the water. It also means that it loses heat very quickly after it is removed from the heat source which isn't ideal from the tea making point of view. Personally I only use mine for heating the water which it does admirably. I use a ceramic, glass or porcelain teapot or gaiwan for actually brewing the tea.

Many books attribute that ability to the "fact" that cast iron is a good conductor of heat. But the truth is exactly the opposite. The reason it holds its heat so well is that cast iron is a relatively poor conductor of heat: one-third as good as aluminum and only one-fifth as good as copper.

I agree that cast iron in tea is best used in a good, unlined tetsubin. If one likes the aesthetic of a lined cast iron teapot, have fun with it. But few people who are serious about tea will use cast iron teapots, because frankly, ironwares aren't very good for that purpose.
