The lost wax casting method
It is said that this method began in Ancient Egypt. In Japan, this method has been in use since the Nara-period.
This method is suitable to express smooth and detailed patterns.
The prototype are formed using a mixture of pine tar and bee’s wax.
And so the prototype are covered with mud(called Mane) from fine to coarse in layers.
After natural drying, the mold are heated slowly with charcoal fire melt the wax out. Then molten metal is poured into molds.
At this time, Mane is baked, hardened, and tightened by the heat. As a result, inside the Mane a hollow space forms exactly the same as the wax prototype.
We pour melted metal into these molds and break open the Mane once cool extract the rough cast products.
With this method, there’s no molds or prototypes left after casting, the products will remain original, unique, and cherished eternally.
After the process of casting and polishing, the pieces are baked and reheated using high quality charcoal fire to let the pieces express beautiful speckles. The process and timing of heating them up and pulling them out right before they melt is crucial. This is the moment when the products decide to show their own beauty brought through the power of the nature.
To let these pieces express beautiful speckles, the combination of metal and timing of pulling them out from the fire is crucial. It takes time and experience to master these skills.
Hanshidou is blond with speckled purplish red patterns.
Not a single speckle brought out from the flames is the same. Each piece has its own beauty as if they have a life of their own.
