Tetsubin cast iron kettles

A tetsubin is bare cast iron with no enamel lining, made to sit over a flame and boil water. The trace iron it releases is part of the point: it rounds out the taste of the water, and the tea made with it. Ours are Nanbu tekki from Iwate, including pieces by Oigen and Iwachu. Not to be confused with an enamel-lined cast iron teapot, which is for brewing only and must stay off the heat. Care instructions are in our tetsubin care guide; see also all cast iron teaware and our tea ceremony items.
