Editing Tetsubin (section)

==History==
It is not clear when the first tetsubin kettles appeared in Japan, but one hypothesis is that the popularity of the tetsubin grew alongside [[sencha]], a form of leaf tea. China introduced Japan to sencha around the middle of the 17th century.<ref name="History of the tetsubin">{{cite web|title=History of the tetsubin|url=http://researcharchive.calacademy.org/research/anthropology/tetsubin/hist.html|accessdate=30 December 2011}}</ref> Sencha was not considered as formal as [[matcha]], the common powdered green tea at the time. Throughout the 18th century, people started drinking sencha as an informal setting for sharing a cup of tea with friends or family.<ref name="History of the matcha">{{cite web|title=History of the Matcha|url=https://www.yutea.com/pages/best-matcha|accessdate=13 July 2019}}</ref> As more people drank sencha, the popularity of the tetsubin grew. The tetsubin is most probably not an original design, but rather shaped by other kettles around at the time. The five closest relatives to the tetsubin are the tedorikama, the toyama, the mizusosogi, the dobin, and the yakkan.

The yakkan is the closest relative to the tetsubin, the main difference is that the yakkan is made from [[copper]], whereas tetsubins are traditionally made out of [[iron]]. Some people have wondered why the tetsubin was developed, when a perfectly usable vessel such as the yakkan would have worked. Tea drinkers may have preferred the taste of water from an iron kettle over the taste of water from a copper kettle. Throughout the 18th century, tetsubin kettles became a standard household utensil for heating water to make tea with. As the use of these kettles increased, so too did the intricacy. During the 19th century, tetsubin designs went from simple basic iron kettles, to elaborately engraved masterpieces.
