Our copperware is created by hammering and shaping
a single sheet of copper into a finished item.
As it is hammered, the copper becomes harder,
and it is necessary to soften it again at regular
intervals by heating and cooling it.
Once malleability is restored, the piece can then
be further shaped under the hammer.
A kettle made from a single sheet of copper,
for instance, may go through as many as 15 iterations
of this shaping-softening process.

After shaping is complete,
the piece is individually coloured using oxidizing
methods developed over seven generations.
The plating and baking of tin onto the surface of
the piece also allows the artisan to achieve colours
not possible with copper alone.
After the patina is applied,
natural Japanese tree wax is melted and spread over the surface.
Through daily use, this wax will slowly fade,
but will help to create luster and shine.

Below are just some of the different tools and techniques
that Gyokusendo artisans use to create their unique works.
