How to Properly Use Your Cast Iron Teapot or Kettle Type of Tetsubin

To assure the longevity of your cast iron teapot or tetsubin non kettle type please follow these basic guidelines:

Before using your cast iron teapot for the first time:

  • Thoroughly rinse the teapot with hot water.
  • While the teapot is still warm, dry the teapot inside and out with a dry cloth.

When using your teapot always note the following:

  • Use the cast iron teapot to brew tea, not as a stove-top kettle. The enamel lining is fragile and could be damaged.
  • Never use in a microwave oven.
  • Do not scrub the teapot with abrasive pads or use any detergents, simply rinse it with water ONLY and wipe it dry after each use.
  • Do not leave any tea or water in the teapot for long periods of time. Always wipe the outside with a dry cloth while the teapot is still warm.
  • Do not expose the teapot to salt or oil.
  • Never use a dishwasher to clean it.
  • Never suddenly cool the teapot when it is still warm.
  • The inside of the teapot is glazed, so choose kitchen utensils that do not scratch the glaze; by doing so you will be assured years of enjoyment from your teapot.




Use & care instructions for kettle type tetsubin which can be used over a flame:

To season the cast iron tea kettle/tetsubin for the first time, place it on the stove and boil water in it, next pour the water out. You can boil tea in the teapot a few times to help get rid of the new interior coating odor.

After you finish using the teapot each time, pour out the excess water from the cast iron teapot/tetsubin The remaining heat will evaporate any excess water. Remove the teapot lid while the teapot is drying.

You may notice red spots on the bottom of the teapot after about two to three weeks after first use. This is normal and is no cause for alarm. You may also see white water marks and this too is also normal and is not unusual as they will help to prevent rust. In Japan, a natural mineral layer buildup from use is considered to be good for the health and to help prevent rust from forming.

Please do not wash or rub the teapot inside or outside with a sponge, detergent, brush or cleaning implement. Do not leave water inside for long periods of time after use.

You may polish the surface of the teapot with a lightly squeezed soft cloth, which has been soaked with tea as this will help to keep it looking glossy.

Indentations on the bottom of the teapot are normal and are formed during the process of making the teapot.
