Nambu Ironware




To assure the longevity of your cast iron teapot or 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.
