Cast iron teapots were created in ancient China. They were then adopted and further developed on by Japanese into practical as well as decorative handicraft items. They symbolize the everlasting strength and unity of the world.
China is best known for its cast iron products. Through special chemical treatment, impurities are removed from the cast iron during the production process. A coating of misty black enamel is then applied to help prevent the development of rust. These pots should only be used to serve tea. They should not be used to boil water directly. There is a special instruction for proper use:
1. Before using, rinse the pot with boiling water 2-3 times.
2. After each use, make sure that the entire pot is clean and dry, wiped with a dry cloth, especially where the lid is situated. This will keep your teapot from rusting, since it's not enamel coated from the outside.
3. Do not keep tea in the pot overnight.
4. In the unlikely event of rust, the pot can still be used. After cleaning the rusted area with a soft brush, steep tea leaves in the pot. The tannic acid from the tea will naturally react with the iron, producing a black seal, covering the rusted area. This will also prevent the re-occurrence of rust.
5. Dishwasher cleaning is not recommended.
6. Don't wash the pot with detergent.
7. To prevent the enamel coating from damaging, do not drop or bang the pot. Despite being strong, the teapot may break if dropped.
8. Store in a cool, dry place. It can also be put on display to evoke moods of ancient China.
