To make BAMBOO SALT, minced sun-dried salt cultivated in the west coast of Korea is put into a bamboo receptacle made out of golden bamboo that is more than three years old, and then the inlet of the bamboo receptacle is plugged with red clay fetched from deep in a mountain and it is roasted in an iron pot over a pine charcoal fire nine times.
If it is roasted with a pine charcoal fire once, the bamboo is reduced to ashes and the salt melts and becomes a white pillar. During this, bamboo oil infiltrates into the salt by the force of fire. The hardened salt lumps are ground into powder and then put into a bamboo receptacle again. With this cycle, it is roasted eight times more.
Every time it is roasted, the salt color becomes darker grey. And when it is roasted the ninth time, resin is sprinkled on and the temperature of the heat is raised to over 1500°C with a specially manufactured tool. Then the salt melts and flows down like lava. If this is cooled and becomes hard, its shape becomes like stones or ice. BAMBOO SALT is completed by grinding those lumps into powder for easy intake.
The major materials of BAMBOO SALT are sun-dried salt, golden bamboo, pine, and red clay. They all should be made in Korea. This is because the salt from the west coast of Korea on the Korean Peninsula contains the most medicinal properties and the bamboo grown in Korea also has many medicinal properties needed.
MANUFACTURING METHOD OF OCKSUJUNG BAMBOO SALT
Make bamboo containers
Golden bamboo that more than three years old is cut between nodes with one end open and the other closed.
The sun-dried salt from the west coast of Korea is minced and put fully into the cut bamboo receptacle.
Seal with red clay
Mud without fertilizing properties is collected from deep in a mountain. Sand is removed from the mud and thick dough is made out of the mud. With this, the inlet of the bamboo receptacle is closed.
Boil and melt
The bamboo receptacles containing salt are set together densely in two to three layers with the mud side up and a fire is made in a furnace. Here, a small amount of chemical resin is added to enhance the fire power. The BAMBOO SALT is dissolved by the strong fire power and flows down and becomes hard like stone.
Repeat 8 times
After the bamboo has burned out, the charcoal in the drum is picked out and the salt is sorted. Among the salt, lumps are pounded roughly in a mortar and then they are put in the drum to be roasted again. With this cycle, roasting is repeated eight times.
Process at a high temperature
In final ninth roasting, the fire burns only with chemical resin so as not to make ashes. With the high temperature heat at thousands of degrees, salt melts down like water. This becomes like a lump of stone once the fire goes out.
