"Teacup Wan Haku Sumikannyu"
Nankei, the beauty of precision and minimalism
The headquarters of the small, noble manufactory Nankei is Yokkaichi, in the middle of the Banko area. The philosophy, this friendly pottery could be described as \"simply beautiful - simply good\". The design of Nankei products is minimalistic, formally very balanced and appealing. Classical craftsmanship at the highest level is the basis of any production, which, however, has been and will be further developed with new tricks of the trade. The masters are experienced, have the necessary sensitivity and work extremely precisely. The assortment of Nankei offers beautiful teapots, tea bowls and mugs, matching plates and bowls, as well as some other beauties like vases and pots. The tea ware is - of course - not glazed, as this makes the tea softer and even more pleasant. After all, Nankei wants the savvy tea drinker to fully enjoy the benefits of natural Banko clay - Banko Yaki. Designs range from classic to modern, with some daring formal feats to be found as well. All products are pure nature, absolutely no adhesives are used and, for some products such as tea bowls, only natural glazes are used.
Teapots made of clay: characteristics, origin and firing method are closely related
The four most important places where Japanese clay teapots were made are Mie Prefecture (Banko Yaki), Gifu (Onko Yaki), Aichi Prefecture (Tokoname Yaki) and Sado Island, Niigata Prefecture (Mumyoi Yaki). In all these areas there are clay deposits with very high mineral content. Ogaki started the production of Japanese clay teapots (Onko Yaki) only in the 19th century. However, this production no longer exists. What has remained, however, is the method he introduced of making Japanese teapots from clay on the potter's wheel. Even in the most important places - Tokoname by far, followed by Yokkaichi in Mie Prefecture - Japanese clay teapots are still made on the potter's wheel by renowned artists. The firing methods used are reduction firing and oxidation firing. While teapots made with the reduction firing have a rather slightly attenuating to neutral character and are recommended for all types of green tea, teapots with oxidation firing rather intensify the variety of flavors of green tea.
Tokoname Yaki and Banko Yaki
Tokoname and Yokkaichi are probably the most famous places for ceramic products of the highest quality, especially the Japanese teapots. The two cities are located at nearly the same elevation southwest of Tokyo, separated only by Ise Bay on Japan's Pacific coast. The clay from Tokoname is red, while that from Banko is purple (violet) or yellow. Both are very rich in minerals and iron. What are the key differences for tea lovers? Tokoname clay teapots are \"baked\" using either the oxidation process (red teapot) or reduction firing (black teapot). The red teapots are recommended more for mild teas, the black teapots are green tea of any variety very good to good. The purple-colored Banko Yaki is processed at very high firing temperatures, which further activates the already high iron content. The surfaces inside the teapot are usually quite porous, which on the one hand allows the teapot to release minerals to the tea very well, and on the other hand allows ingredients of the tea to be deposited in the teapot, which increasingly leads to flavor enhancement and harmonization with use. Teapots made of Banko-Yaki are especially recommended for high-class, mild tea varieties such as Gyokuro, Kabusecha or noble Sencha.
The advantage of natural clay
The difference between natural and mixed clay is that in natural clay, the iron is in crystallized form. In clay to which iron is \"artificially\" mixed, the iron has been ground beforehand. This process results in a different, uneven and more extensive surface, and the melting point is usually much lower than that of natural iron. And this entails that clay tableware made of clay or loam, to which iron has been added, must be fired at much lower temperatures - about 600-800 degrees - while Japanese teapots made of natural clay can be fired at up to 1200 degrees. This not only increases the strength of the final product, but also the material transformation is affected by the temperature. Most clay teapots - especially mass-produced - from China but also from Japan today are made from artificially mixed clay.
Cleaning Note
Rinse the exterior and interior with warm water only. Do not use any cleaning agents. If necessary, remove contamination with infused green tea. Use creates a tea patina that you do not need to remove, as it gives the tea cup its own character.
