Cast Iron Teapots: Tetsubin Style Cast Iron Tea Kettles, Tea Cups & TrivetsCast Iron teapots were created in ancient China and Japan to symbolize the everlasting strength and unity of the world. Today's Japanese style cast iron Tetsubin teapots, with their fine raised relief designs, are admired and collected not only for their quiet delicacy, but also for their ability to brew a perfect cup of tea. Each cast iron teapot comes with a stainless steel mesh infuser and is enamel finished on the inside to prevent rust formation.
Due to their strength of construction these cast iron pots may be used either as a tea kettle (for boiling water) or a teapot (for brewing and serving tea). If using the pot to boil water the infuser should be removed before doing so. Through special treatments, impurities are removed from the cast iron during the production process. A coating of misty black enamel is then applied to help prevent the formation of rust.
Marcus says: Cast iron tea pots are great for keeping your brewing water hot. I suggest that you "charge" your cast iron teapot prior to using it. Charging is simple; pour hot tap water into it and allow the teapot to heat up. You will be able to feel how warm the pot is by feeling the outside of the cast iron teapot. Cast iron is a little slow at conducting heat, but once the heat is conducted the cast iron will retain it for a long time. Once the teapot is warm, pour out the hot tap water and pour in your hot brewing water. This step will keep your tea or brewing water hot for much longer.
