Nambu TekkiNambu Cast Ironwork

The beginning of 17th century, it does by opening that southern part feudal clan which ruled area around current Morioka-shi, Iwate invited teakettle craftsman to Morioka from Kyoto.
We called many founders, teakettle craftsman together in southern feudal clan from each place and let you make weapon and teakettle, daily necessities afterwards. It came to be used by opening widely by simplicity that famous Nanbu iron kettle was the 18th century and made teakettle small size and improved.
On the other hand, production of casting of daily necessities was prosperous, and, in area equal to current Oshu-shi, Iwate that was under the control of Date feudal clan, technology exchanges of both production centers advanced after the Meiji era and came to call casting made in Morioka and land of both Oshu in the 30, Showa generation with Nambu Tekki collectively.

Present-day Morioka is at the center of an area which was controlled by the Nambu clan at the beginning of the 17th century. It was then that craftsmen practiced in the art of making chagama or pots used to heat water for the tea ceremony were invited to Morioka from Kyoto. Many more casters were subsequently engaged by the clan and the production of weapons, chagama , and other pots began in earnest.
The now famous Nambu Tekki teakettles were the result of refining and scaling down the larger chagama, a process which happened in the 18th century, and they became widely used because of their lightness. Cast-iron kettles were also being made in the adjoining area of Mizusawa, which in the past was governed by the Date clan. During the Meiji era (1868-1912) there was an exchange of ideas and techniques between the two areas, leading to the cast-iron work from this larger area being called Nambu Tekki from the 1950s.

The durability and rich yet unassuming character of Nambu Tekki is well known and the distinctive raised spot patterns on the teakettles and chagama somehow speak of the warmth and spirit of their makers.

  • Work scenery

    We introduce process of manufacture of iron kettle which is representative product of Nambu Tekki here.
    There are work processes more than 80 before iron kettle is done and, from design to completion of product, may suffer for nearly two months.
    Craftsman making the body and craftsman specialized in string are in iron kettle, and splendid work is completed only after these two skill becoming one.

    Process 1: Drawing figures

    We draw form of iron kettle which we are going to make on paper. Generally, it is iron kettle which often makes round shape, form of flat round shape, but makes original thing.
    We infer cross section from drawing next and make "shoe tree" to make mold with iron plate. This model is made of iron plate, but the name called shoe tree which was called from old days because we used tree before remains.
    Three of trunk type and buttocks type equal to half equal to half of the bottoms and cover are necessary for shoe tree on mold of the iron kettle body. We turn these shoe trees and make each mold.
    In addition, we make shoe tree for core to make core (basket) squeezing up in mold in many cases when we make shoe tree of mold. Core is intended to make cavity in iron kettle, and hold shoe tree for core for thickness of iron kettle than model to make the outside, and it is to small thing.

    Process 2: The making of mold

    We mix juice of clay and clay called henashiru (is ashamed) with sand of a river and put in the unglazed bounds of true model (seeds). We fix shoe tree in the center of true model and we turn and make mold.
    Sand of a river does eye with three phases to process to make form finely. At first, we make approximate form using rather rough sand and join mold of fancy ice water of fancy ice water (of seed) equal to beak to implantation, the body. Then, eyes are slightly small in sand to mix with clay; get, and fix form. Finally we build up inside aspect to contact with iron flowing using small sand of eyes very much which we wielded by silk to smooth thing.

    Process 3: Pattern push, skin beat

    Work of pattern push is carried out before mold dries. Famous "hail" acquires 3,000 designs using model pushing rod as design of Nanbu iron kettle one by one. We push pictures such as flower or scenery using various tools, and, other than geometric design, there is finished thing such as relief.
    "Skin hits" skin aio work to give that is attractive one of the Nanbu iron kettles; toiimasu. We sprinkle sand of silk-strained bean curd on trunk type and we touch thing which we dissolved Masago and fertile land in in henashiru in cloth tampo and nail over trunk type and we touch on writing brush and put on trunk-shaped skin and do and provide condition of skin.

    Process 4: The making of core

    Using shoe tree for core which we made earlier, we make core collecting type with the point same as mold and do grilled model. Mix henashiru, and grilled sand which burns sand of a river and sand, and removed impurities also makes core sand. We put core collecting type on potter's wheel and we push core sand to the inside of model and do into a bowl form and make trunk type and buttocks type of core. We glue completed trunk type and buttocks type together in henashiru and dry with the sun well and completely remove moisture of core.

    Process 5: Drying, burning of mold

    After having dried, we bake completed trunk type, buttocks type at around 800-1000 degrees on charcoal fire for approximately two hours. Careful quenching crack that we occurred then revises with writing brush and spatula. (deaeration collecting)
    We make hot water way to stroll around *tetsu, and to put in the buttocks type next. Similarly, we prepare hot water way into mold of part of cover, and production of mold is over. Furthermore, we hang oil smoke in the inside of mold and cover the surface of model and prevent that *tetsu is branded on mold.

    Process 6: Assembling of model

    We do trunk type below and put core in that. We put two or three places of small pieces of iron called chaplet (keep) on the buttocks of core and cover with buttocks type from the top. Chaplet is intended to prevent core from rising when we poured *tetsu and becomes a part of iron which we cast.

    Process 7: Cast

    We dissolve pig iron and make *tetsu with a certain big smelting furnace more than 3 meters called "Koshiki". Pig iron, scrap iron, limestone are put in the smelting furnace other than coke of fuel. We melt at high temperature from 1,300 degrees to 1,400 degrees in furnace and mix. Iron which melted is called hot water. The inside called "toribe" receives hot water beginning to flow from getting out hot water mouth of smelting furnace with ladle made of red earth and flows into mold from hot water way.

    Process 8: Finish

    If *jo gatta type gets cold, open up model and take out product. We break core with metal stick next and remove sand attaching to middle side neatly.
    We swat part that *tetsu which we injected protruded from gaps of joints of model with hammer or file and we sharpen and fix form and finish the whole with brush neatly.
    We bake completed iron kettle of form by fire of charcoal of 800 degrees - around 1,000 degrees and attach magnetic oxide film to iron kettle. This processing is called "metallic taste coup de grace", and attached film prevents rust. Technique of metallic taste stopper began with Nanbu iron kettle.
    We polish oxide film accompanied outward with brushes and remove to burn the outside of iron kettle on fire directly, and to be capricious.

    Process 9: Abrasion and the coloration

    Water leak gives a test whether or not there is not and moves to coloration process without problem. We heat iron kettle which we finished of finish at temperature of around 200 degrees on charcoal fire and do appearance in state that filtrate to tear off which mixed rust of lacquer and iron of finish with juice to acetic acid and tea is easy to get on. We paint with lacquer by brush which we made with kugo grass while heating iron kettle and print. We paint iron kettle which finished priming with lacquer with "we tear off" or "tea juice" by brush and finish.

    Process 10: Production of string

    Because we are made by forging (forging), craftsman who is specialized in string produces string. There is "sargasso" to bend method called "bag zuru" to round one piece of iron plate, and to make and round stick, and to make. In "bag zuru," there are hardly only some people who can perform this technique in elaborate technique.
    It is completion if we attach string to the given body of coloration finish.

    Iron Nambu Tekki of Morioka representing Traditional Craft

    Boil hot water, make tea. Nambu Tekki which gives color and ease in the person. Of "Nambu Tekki speaking of Officially designated Traditional craft products", as for the cast iron of Morioka that was well known in the whole country so that the name is given, the southern part is full; while was brought up naturally, warmed daily livings.


    With Ayumi southern part feudal clan of Nambu Tekki

    It is about 1975 that Nambu Tekki caught the first designation of Officially designated Traditional craft products. The history of Nambu Tekki originates in middle part of the 17th century when southern feudal clan constructed a castle in Morioka retroactively to old days of 350 years. After that, in Morioka that wood for iron sand and charcoal becoming raw materials produced abundantly, the name will be known to the whole country as big production center of cast iron.
    Only teakettle was made at first, but we repeat invention, and various daily necessities such as pan, wind-bell, accessories come to be made other than iron kettle which should say with pronoun of Nambu Tekki now.
    In late years health benefit of iron which begins to melt from ironware is known, and boom is caused, Nambu Tekki which is high as for the reevaluation from not only seemliness but also practical use side. We visited "Morioka handicraft village" where we collected studios made with the Nambu Tekki and heard story.

    The world of craftsman who is boundless if we go to the top

    "Thing sold in 3-5 years becomes able to form, but this is because it is this world that there is no bounds to the top if we go." Maeda who talked so is one of five studios in Morioka handicraft village, master of Kozan Craft Shop. Including Maeda, three craftsmen sweat for the making of ironware. "Originally it is open one of Nambu Tekki, but we come to make myself and are 20 years." "It is work that is pleasant if we can endure for five years. There are many people resigning." as With forbearance that it is said to wear the skill by longtime effort in the world of craftsman cultivating the skill by everyday steady effort, research feeling that it is said to polish the skill is indispensable nature more.


    Work that mixed of stillness and violence

    The violence serves, and, in work of craftsman with much delicate work to be continued still without sound, the making of ironware is outstanding. Maeda who files beak of ironware while telling story. "Note giyasusaga is entirely different in this." The sound to sharpen iron affects wooden goods in head by few height. Even hot water needs iron by the incandescence more than 1,300 degrees with cupola dissolving iron. Work to push pattern giving expression in iron kettle to mold does not cost one sound in contrast. 3,000 times per iron kettle having one this quiet work. Violent work, quiet work are repeated, and ironware is completed.
    And, to appear by work, is intense, standing opposite to sound, mouth of craftsman continues remaining silent. Minute work continues silently in violent environment.

    Gold sound to reduce with file resounds

    Is handling of ironware difficult?

    "There are many people thinking that iron kettle must excite in charcoal, but not at all. You should excite with gas. And, we do if we have you use." It is said that and many people think that iron kettle is easy to be rusted or we are concerned too much. If "bath is heated here, we move in pot. Because iron kettle becomes hot, we dry immediately if we drink up hot water and leave alone. With that alone it is rust-free." Iron kettle endures use of long interval for just little consideration. Color may not go to live even if there are sonochottoganakereba, iron kettle.

    Iron kettle which we can repair even if hole becomes vacant leads to resources saving

    Development of products, personnel training that fixed their eyes on the times

    In late years apartments only for electromagnetic cooker without gas ring increase from the viewpoint of disaster prevention. It is Secretary General Konno of Nambu Tekki cooperative association to work on development of new product to such a living environment positively. "Biography warigayoku of heat is earlier than kettle made of stainless steel and boils." We are active in the making of iron kettle for electromagnetic cookers. Konno works on craftsman and promotes the making of product which fitted in the times. Nambu Tekki supports popularity such an effort behind the scenes.
    In addition, it recruits successors positively from outside the prefecture. Is the world of craftsman who is quieter than gaudiness of the world, but "Nambu Tekki is tradition of native district to be able to be proud of to the world. There are many together youths in appeal, we want youths with spirit to say to take this technique to gather, too.

    Nambu Tekki which is reviewed from the viewpoint of health and energy saving. It seems to be to the thing that everyday teatime rose still more by being made, and mentioning one and spirit of craftsman.

    Is master of tiger mountain (kozan) studio, Master of Traditional Crafts. "It does not turn out that we do not open mold. Concentration to work does not break off even if an expert saying "casting is demon.".


    Letter from nice reaction children

    There is curriculum to learn traditional industrial arts of each place from fifth grader. Many children do well known Nambu Tekki for visit in Officially designated Traditional craft products. Letter seems to have been often sent from children who came for visit at the future, and letter of photograph is one case. Elaborate manufacturing method and expertise of Officially designated Traditional craft products seem to impress not only adult but also children, and surprise and curiosity of children are felt from letter. Such a reaction seems to be very nice for craftsmen, all of associations. Not only it knows merely technique to know traditional industrial arts, but also including the way of the change, work of local culture and history may be most suitable to know things generally.
    Put letter is handwritten; of picture and character was written, and there were many things which overflowed of individuality, but took image using PC probably because reflected the present age among them, and there was thing of excellent look that wrote character by word-processing software. For thing which children made, we feel some dullness. Is the skill due to hand necessary for letter?

    • Many thank-you note and reports put by children

"We are strong, and oblong chest" this is image of Nambu Tekki "simple and sturdy". In addition, various patterns and pattern of "hail" (hail) which grain that formed a line beautifully draws drawn in tea ceremony pot and iron kettle let subtleties and warmth of heart of people making feel.

“Spartan design” and “durable and long-lasting” are the key images of Nambu Tekki ironwares. The intricate designs and “hail” pattern of stubs on the tea kettles and iron kettles allow one to feel the inner-workings and warmth of the hearts of the great many people that devoted themselves to making each kettle.

How to make

We hit pattern push, skin with method of grilled model, drying type even today, and Nambu Tekki is made with casting with iron as material after processes such as lacquer finish. Above all, it is technique peculiar to Nambu Tekki putting iron kettle in the charcoal fire of approximately 900 degrees Celsius for around 30 minutes that "is metallic taste stopping" (but we cry) to prevent rust (rust) of ironware.

Nambu Tekki ironwares are a cast iron product, and even today follow the same steps of production: molding, drying, pressing the decorations, hammering the surface for finishing, and applying lacquer. A key characteristic of Nambu Tekki ironware is its method of preventing rust even on the inside of the kettle by heating the kettle to 900℃ in a charcoal fire for 30 minutes.
