Joo-Joh

(Casting) is the process of melting iron in a furnace and of pouring molten iron into a mold and the product of this process is called

Ju-Mul

. One biggest advantage of this process is mass production of same shape of product using the mold.

Joo-Joh

normally requires very high temperatures to completely melt iron of the iron ore. Craftsmen of Korea had developed a technology that can produce temperatures of 1,200°C using

Pul-Moo

(a toolbox to supply the wind into the furnace) which was a thousand years earlier than Europe in the 13th century.

In order to cast iron, the process of making molds, melting iron, pouring iron, and surface polishing are required. Each stages of work is done by different people has expertise in that field who has around 30~40 years of experience. It starts from making molds as per design. when the furnace is ready, then starts the process of melting iron which It is the most important stage of entire process.

Melting the iron is the most time-consuming work also a lot of materials are required to be prepared. Again, it is the most important stage because this process determines the quality and the durability of iron product at the end. The entire process is completed, and the final product is ready when pouring and polishing are done.

out-standing craftsmanship and the efforts are always recognized through the process of manual hardening works on the iron that heated up to 1,850 degree (5-10 times), also through the manual polishing using sesame oil.
