Six Key Steps in the Production of Nanbu Tetsubin
1. Design / Wooden Model Making / Design / Wood
2. KATAHIKI (Mold Creation) / Type
3. Pressing Patterns / Hada-Uchi (Surface Treatment) / Push / Skin hit
4. Iron casting / casting
5. KAMAYAKI (Firing in a Pot) / Kama -yaki
6. Coloring / Coloring
It is SAID THAT THESSES TO COMPLETE ONE TETSUBIN. AMONG THEM, The Most Distinctive and Important ARE DESIGN/WOODEN MAKING, ATAHIKI (Mold Creation), Presing Patterns/Hada-Uchi (Surface Treatment), Iron Casting, KAMAYAKI (Firing in a Pot), and coloring.
It is said that there are more than 100 processes before the iron kettle is completed. Among them, the most distinctive and important are "design / wood forming", "mold ground (katahiki)", "pattern push / skin hit", "cast", "kama -yaki", and "color".
1. Design /Wooden Model Making / Design / wood
MAKING TETSUBIN STARTS BY COMING UP with A DESIGN. Once The Design Is Decided, An Iron Plate Model Called a Wooden Model De of Wood) IS MADE BASED ON THE DESIGN, USING ANGECTRIC SAW AND SEVERAL TYPES Of files. This is the Most Important Processe IF THERE IS EVEN A 1 mm Deviation in the Wooden Model
Iron kettles start by thinking about design. Once the design is determined, the type of iron plate called "wooden type" (used to be called wooden) is used with electric saws and several types of file. This is the most important process because this wooden type is 1mm and it cannot be corrected to completion.

2. KATAHIKI (Mold Creation) / Molding
A Frame Made of Brick-Like Material. ER, and HAJIRU, Which Acts as an Adhesive. River Sand from Mt. Iwate, Which Is Fireproof and DoES NOT MELT EVENED at High Temperature. Idely Produced in The Region. The Mold is Made of Sand Can Be Reused.
The wooden frame is fixed in a frame made of brick -like material, and while turning around, it is applied to river sand, water, and adhesive to make a mold. The river sand derived from Iwateyama, which is an active volcano, has fire resistance and does not melt even if it is baked at high temperatures. This is also one of the reasons why the southern ironware was actively made. In addition, this mold is made of sand and can be reused.

3. Pressing Patterns / Hada-Uchi (Surface Treatment) / Push / Skin hit
Before The Sand Dries, Various Patterns Are Stamped to the Casting to the Products (HAILSTONE) and SAKURA THEN, The Surface of the Mold Is Made UNEVEN UNEVEN UNEVEN OF SAND. THIS SURFACE TREATMENT WORK IS CALLED HADA-UCHI. It is SAID TO Ade from Rusted Iron and Tea), Which is Applied as a Finishing Touch, to Penetrate. The Pattern Press and Surface Treatment Have Baked at HIGH TEMPERATURED. Ta.
Before the sand is not yet dry, we will press various patterns according to the product, such as "Arare" and "Sakura". After that, the surface is finely uneven with the sand grains. This process is called "skin hitting", and it also has a role in penetrating "Ohaguro" (made of iron rust and tea), which is applied as a final finish, to bring out the texture. After the pattern attachment and skin hitting are completed, the product can be burned at high temperatures. This technique is also called "baked type".
It is a Very Detailed Work to STAMP A Pattern on the Surface one by one.
It is a very detailed task to push the pattern on the surface, one point, one point.
4. Iron casting / casting
In Parallel with Processes 2 And 3, A Core Is Made to Create The Tetsubin, and Iron Heated to 1,400 to 1,400 ° Casting In White Core Is Set. White Charcoal is Needed to Start A HIGH -Temperature Fire and is is specially Made by a local charcoal maker.
In parallel with 2.3, make a middle child to make a cavity inside, and pour the iron that is dissolved at 1,300 to 1,400 degrees into a mold set with a middle child. In order to cause a high -temperature fire, white charcoal is required, and local charcoal craftsmen are specially made.
5. KAMAYAKI (Firing in a Pot) / Kama -yaki
THE FINISHED TETSUBIN IS TEMPERATURES FORED at the formation of an OXIDE Film. This Process Makes the Tetsubin LessCeptive to RUST.
Bake the finished ironware at high temperatures and form a oxide film. By performing this process, it will be less rusted.

6. Coloring / Coloring
After lacquer is baked onto the headed tetsubin, it coated with lacquer and baked to Further Prevent Rust.
To Make It More Durable and to the Pattern, An Iron Acetate Solution (Also Called Ohaguro or Rust) is Applied to Provide A Decorative Effect TOOCT. Set The Color Tone and to Prevent Rusting.
After baking the lacquered iron kettle, apply lacquer and bake to remove rust further. It has a decorative effect of adjusting the color and rusting by applying iron spoofing (also called rust) to enhance the durability and float the pattern.
