Nanbu Cast Iron Kettles (Tetsubin) — Handmade in Iwate, Japan

In the old days, Nanbu cast iron kettles served multiple purposes in the home. They were used to boil water for household use as well as for making tea. The steam from the boiling kettle was also an economical way of providing extra heat and moisture to the home in the typically cold and dry winters. It is believed that water boiled in cast iron kettles absorbs the iron, a definite plus for those who feel their diets are iron-deficient.
If you are a tea connoisseur who likes to experience the taste of tea brewed in various teapots made of different materials ie. the stoneware pots of Tokoname or the porcelain pots of Arita yaki, you may prefer to use Nanbu cast iron kettles purely for the process of boiling water. The kettles shown here do not have enamel coated interiors and are not suitable for brewing tea. They are suitable for use over a naked flame, on gas and electric rings and have been specially treated to resist rust (although care still needs to be taken and water should not be left in the kettle).

Please click on the pictures below for enlarged images of these lovely traditional Nanbu cast iron kettles. The height of each kettle is measured at the highest point of the handle. It is recommended that you fill only up to 75% of the total volume as water tends to spill over while boiling. Please bear this in mind while making your selection.
