Ways to Finish Copper Items
As a company that has been making copper products for over 400 years, we at Tazen believe thatcopper products are something that are best enjoyed by “nurturing over time.” The surface ofcopper products start to change due to chemical reactions immediately after they are put to use;
however, the true beauty of copper is found in the changes that is generally considered degradation. As you continue to use our copper products and witness the developing expression, wehope that it will inspire you to enjoy the spirit wabi—appreciating the aging changes. For thatpurpose, Sendai Douko presents three finishing methods.

So— Natural
The Chinese character for “So” means “natural state.”
With this method, nothing is done to the product otherthan physical processes such as hammer tone and bending. Enjoy the copper’s natural texture, presence, andnurture it from scratch.

En— Fl amed
En is a finishing method where a copper plate is burned
with a flame. With this primordial processing method,
rainbow-like color patterns of red and yellow emerge on
the surface by putting the oxide film in the fire. Enjoy thechanging expression of the copper, reflecting the flickering of the flame.

Sen— Dyed
Sen is a finishing method that is used to dye the copper
black by applying a sulfurized film on the surface of thecopper plate with a potassium sulfide solution. If “En”
is born from fire, “Sen” is born from water. Nurturing
starts from restrained texture—Sen is often described asa finish for connoisseur.

About Sendai Douko
Douko, which literally translates as “copper pot,” is a Japanese word for copperware that is used
to boil water with a heat source, often attached to the side wall of a stove or buried in the ashof a brazier. Initially, it was a simple tool to boil water in a brazier, but various functions weregradually added, such as cooking ingredients, and it became an integrated kitchen system of theEdo period. In the early 20th century, the Sendai Douko, produced by Tazen in Sendai, became
popular throughout Japan. We are revisiting this Sendai Douko tradition as contemporary take
