Caring for ​​Japanese Tetsubin
​Nanbu Iron Kettles

---

​- To season your kettle for the first time, place it on the stove on medium heat and boil water in it, then pour the water out. Boil water in the kettle a few times to continue the seasoning process.

- After each session, empty the Tetsubin completely while still warm. The heat will help evaporate any excess water. Remove the lid until the interior is completely dry after each use of your kettle.

- You may notice spots on the bottom of the teapot after first weeks of use and you may also see water marks. This is normal and will help to prevent rust. In Japan, a natural mineral layer buildup from use is considered to be good for your health and to help prevent rust from forming.

- Please do not wash or scrub the kettle inside or outside with a sponge, detergent, brush or cleaning implement. Do not leave water inside for long periods of time.

 -​Indentations on the bottom of the kettle are normal and are formed during the process of making the Tetsubin.

​Notes:  Soap, salt and oil should never come into contact with your Tetsubin kettle.  Do not scrub your kettle with anything abrasive.  A natural mineral layer will build up over time and will further protect the interior of your Tetsubin.  You may use your Tetsubin unlined tea kettle to heat water on a stove.  Do not allow your kettle to remain on heating element when dry and do not pour cold water into a hot kettle or boiling hot water into a cold kettle.  Gently heat and cool to avoid damage to the cast iron.

Enjoy!
