Colorful exuberance -- a distinctive feature of Kutaniyaki ware

Kutani-yaki porcelain is named after the place where it was first produced. The village of Kutani is nestled beyond the Yamanaka Onsen hot springs in Kagawa city, Ishikawa, which is along the Sea of Japan coast. Kutani-yaki ware is distinguished for its over-glaze painting using Kutani-gosai, or the "five Kutani colors" of green, yellow, red, purple and dark blue.

Uwa-e-tsuke: over-glaze painting

Uwa-e-tsuke is the unique painting technique applied after glazing. Pigments are used to draw patterns over a glaze, before the clay is fired again.

The same technique is applied to other Japanese tableware, such as the Arita ceramics of Saga, in southwestern Japan.

The over-glaze painting of Kutani-yaki porcelain is characterized by patterns drawn with the five vivid Kutani colors.

Overglaze painting techniques

Let's quickly go through the three major styles of overglaze decoration.

① Iroe・Gosaite (色絵・五彩手)
The first method called "iroe" or "gosaite" makes full use of the Kutani five colors of yellow, green, dark blue, purple and red. The patterns are outlined in an indigo paint invented by the legendary potter-painter Kutani Shoza.

③Aka-e・Kin-ran-de (赤絵・金襴手)
Kutani ware eventually adopted overglaze enamels featuring red and gold. This technique called "aka-e kin-ran-de" was introduced from China during the Edo period.

The history of Kutaniyaki ware

The first Kutani-yaki porcelain is said to date back to 1655, when a kiln opened in Kutani village under the orders of the local feudal lord Maeda Toshiharu. This was shortly after porcelain stone was discovered from a local mine, and Goto Sai-jiro, a member of the Maeda clan, was sent to Arita in southwestern Japan to study its advanced methods of ceramic making.

The Kutani kiln suddenly closed less than a century later, for reasons that remain unknown. The ko-Kutani, or old Kutani pieces, created during this time are extremely rare and highly valued. They are known for their bold and dynamic outlines decorated with thick overglazing by the classical five "gosai" colors.

About a century after the closure of the Kutani kiln, the Kaga clan launched efforts to revive the lost art, and opened the Kasugayama kiln in the castle town of Kanazawa. Other kilns soon opened across the region, letting rise to new decorative styles of Kutani-yaki ware.

The Miyamoto kiln used very fine red lines, while the Eiraku kiln featured gold. The Yoshidaya kiln focused on reviving old Kutani ware. Porcelain produced during this time is called Saiko Kutani, or "the revival of Kutani"

In the late 19th century, painter Kutani Shouza developed a painting style that combined gold with various Kutani coloring techniques. Shouza's style is recognized abroad as "Japan Kutani." His pieces were exported to Europe after being showcased at the 1873 Expo in Vienna.

In recent years, Kutani-yaki porcelain has been used as gifts by the Imperial Family, and was presented to Prince Charles as a wedding gift.

Kutaniyaki tableware has also introduced a new wave of designs and products suitable for everyday use. Some of these items feature popular animation characters.

Even those with the most untraditional patterns seem to have an unmistakably Japanese feel with warm hues similar to classic Kutani-yaki ware. This is because the overglaze enamels add depth to the vivid colors, while softening the overall tone.

The production process

Now, let's take a quick look at how Kutani-yaki ware is produced.

①Clay making
The pottery stone or pottery clay is mined and dried before grounded into powder. It is then sifted and mixed with water, then strained to remove impurities. The clay is kneaded and rested before shaping.

②Shaping
Various methods are applied to shape the clay, including the use of a potter's wheel (rokuro-seikei) or molds (ikomi).
The shaped clay is sun-dried before firing at 800 degrees Celsius.

③Underglaze painting・firing
The next process is one of the most crucial of Kutani production. The drawing is outlined with a cobalt pigment called gosu. Once the outlines are done, the bisque is coated with a glaze called hakuyu. The glaze turns glassy, making the surface stronger. The ware is then fired again for more than 10 hours at 1300 degrees Celsius.

④Overglaze painting・firing after gold decorations
The pottery is decorated with the five Kutani gosai colors, under a process known as uwa-etsuke.The piece is then fired for 4 to 10 hours at temperatures around 800 degrees Celsius.
After this, gold and silver decorations are applied. The piece is complete after a final round of firing.

After washing, always let it dry completely. This prevents mold and odor. 
Extra care is also required for tableware decorated with gold or silver. Never use them in the microwave or the paint will come off, or turn dark. Also, never stack ceramics and porcelain on top each other, otherwise the legs of the porcelain will damage the ceramics' surface.
