“Iron hammering" is a technique first started in the Edo period (1603 and 1868). It uses one entire piece of cast iron, shapes the finished works by heating and hammering. The flexibility of iron is the lowest among all other types of metal, therefore, the hammering technique was considered one of the most difficult and time-consuming techniques in metalwork making. After the Meiji era, this technique has almost gone to extinction.
This kettle is an Edo-period work. The body and handle are silver wrapped in cast iron, with gold-inlaid flying dragon and phoenix pattern on two sides. The entire kettle is extremely light comparing to other cast iron kettles, as the body has been hammered so thin and has a silver lining to prevent rusting. Even after 400 years, it still holds its charming shape, revealing a gorgeous glow to the audience.
