The iron kettle is not for the tea ceremony. It is to boil water for brewing green tea. In the era when it was made, it was used in the living rooms or in the ladies' quarters on a brazier. Its shape, as well as its details, are both exquisite to the point that it can be relished individually. It is a connoisseur's joy to find a utilitarian object that has surpassed its function and enters into the realm of an art object. It all depends on the craftsman's mastery and his mindset, as well as the discerning perception of its collector.
