Japanese cast iron teapot is a very popular Japanese handicraft in recent years. Exquisite workmanship and high price, the boiled tea tastes delicious and can supplement the iron needed by the human body. Therefore, Japanese cast iron teapots, like Japanese toilets, are often robbed of goods.

Japanese cast iron teapots are divided into coated and uncoated ones. Specifically, their differences are as follows:

1. Compared with the uncoated iron pan, the coated iron pan can raise the water temperature and have stronger heat storage capacity.

2. The coated iron pot can soften the water quality, release ferrous ions and form a mountain spring effect.

3. When iron pot is heated, it will release a large amount of ferrous iron, which will react with tannic acid and tea polyphenols in tea to supplement the iron needed by human body. In this respect, the coated wok is slightly inferior to the uncoated wok.

The price of most coated iron pots is much higher than that of uncoated iron pots.
