Handmade Pure Copper (tecubing)
Tetsubin (鉄瓶) is a traditional Japanese cast iron pot having a pouring spout, a lid, and a handle crossing over the top, used for boiling and pouring hot water for making tea. Particles of iron interfuse with water While heating.
Tetsubin appeared in the Middle Ages as a traditional homeware and had been placed near the fire in cold seasons to keep water hot. Its wall retain heat for a long time, so it stays extremely popular in northern provinces. But since the growing popularity of Senta tea (when the tea ceremony became popular not only among aristocrats) tetsubin turned to be the Japanese equivalent of expensive Chinese adobe clay teapots.
During the tea ceremony tetsubin should be heated over a burning coal on a small brazier, but nowdays you are free to use electric stove. Despite the fact that tja-no-yu water is to be heated in a tjagama cauldron, tetsubin can also be used for that purpose. For example, when the ceremony is being held open air or in kaiseki ryori.
Today tetsubin is an increadibly stylish attribute of a tea master, a symbol of status, a collector’s item. It really has character, setting the mood and emitting a special atmosphere ... But it also requires special attention and care. Cast iron is exposed to rust. Therefore, after each use you need to dry tetsubin precisely (calcinate it) and store it in a dry place.
