Description

What is Mino ware ?

Mino ware (called Mino yaki in Japanese) is a ceramic ware produced in the Tono area of Gifu prefecture. It has maintained its long history and tradition but adapted for modern times. A notable feature of Mino ware is its wide variety of pottery. Mino ware does not maintain a single style, but instead has over 15 types of pottery registered as traditional handicrafts.
Here are three notable types of Mino ware. The first is Oribe ware which was based on the aesthetics of Oribe FURUTA, disciple of Sen no Rikyu (influential master of the tea ceremony, 1522-1591) and it has a deep green glaze, an unique form and geometrical design patterns. Depending on the style of production, many kinds of colors are available including black and blue.
The next notable type of Mino ware is Setoguro, an all black glazed item that was mainly produced during the Tensho period (1573-1593), produced by being pulled out of the kiln while still red-hot. Therefore it is often referred to with the names of tensho guro after the name of the period it was first made during or hikidashi guro which means to pull out.
Shino ware is the third notable type of Mino ware and has design patterns underneath its glaze. During the Azuchi-Momoyama period (1573-1600), Shino ware's golden age, it possessed a beautiful light crimson color and bubbly texture produced by feldspar glaze. Production of Shino ware disappeared during the Edo period (1603-1868) but Toyozo ARAKAWA (1894-1985), who was given the title of Living National Treasure, made tremendous efforts to revive it and was able to bring it back.
Kizeto, which has lately received renewed attention, is another popular kind of Mino ware with a humble and simple form.

History

Mino ware - History

Mino ware was created during the 5th century when Sue ware, potter's wheels, and hillside kilns were brought to Japan from the Korean peninsula. During the Heian period (794-1185), Sue ware white porcelain was improved by being fired with an ash coating glaze.
From the Azuchi-Momoyama period (1573-1600) until the beginning of the Edo period (1603-1868), the rise of the tea ceremony brought a wealth of artistic pottery. The prominent types of Mino ware like Oribe, Shino, and Kizeto are extremely important. Then during the second half of the 17th century, household containers for daily use started to be produced and pottery covered in white glaze to look like porcelain started being produced. In the final years of the Edo period (1603-1868), porcelain production began and translucent feldspar porcelain came to be produced.
In the Meiji period (1868-1912), various new techniques started being developed like sheet copper and screenprinting as the coloring process was given security by the importation of a blue and white dyeing colorant. Around the middle of the Meiji period, daily household containers started to be produced by larger manufacturers, lowering the cost. Then, at the end of the Taisho period (1912-1926), mechanization advanced by electricity supply increased the production volume, which changed the woodburning climbing kilns to charcoal kilns.
During the Showa period (1926-1988), production of fine items and tiles started, and Mino ware became the form of pottery boasting the greatest production in Japan, both in terms of prestige and volume.

General Production Process

  1. 1. Clay kneading Clay with a sufficiently uniform hardness and moisture level is kneaded little by little while rotating. The rotation serves to remove the air bubbles from inside the clay. Because the kneading involves both large rough massaging and smaller careful massaging, the form of the clay ends up resembling a chrysanthemum while it is being kneaded hence its nickname, "chrysanthemum kneading".
  2. 2. Casting Mino ware is mainly produced by potter's wheel casting, hand rolling, or slab building. Mass production is carried out using a great variety of templates, from prototype models to working molds. A slip casting produces muddy clay inside a concave plaster mold. Pressure casting is a method of casting that uses compressed air to send clay mud to a plaster mold. Other molds that may be used include mechanical potter's wheel molds, fully-automatic molds, and press molds.
  3. 3. Drying Once the pieces have been planed or shaved down, they are slowly dried before the bisque stage. They are dried in the shade or under the sunlight. The time required for drying varies depending on factors like the application of patterns, decoration, and the thickness of the unglazed pottery on which patterns are drawn, as well as the size of the pieces.
  4. 4. Bisque firing This process removes moisture from the raw material and increases durability by burning combustible material.
    The firing is carried out slowly at a temperature of around 700 to 800℃ (1292 to 1472℉). The bisque firing makes it easier to apply glaze.
  5. 5. Underglaze decoration Underglaze decoration is a process carried out prior to glazing, and patterns are drawn beneath the glaze.
    After the bisque firing, brushes and colorants of desired colors are used to decorate dried, unglazed pieces. Cobalt, iron, and coppers are the most used colorants.
    Once the drawing is complete, clear glaze is applied over top. When using cobalt oxide, which turns colors into indigo blue, pieces drawn with iron are colored in dark reddish-brown or blackish-brown.
  6. 6. Glazing. The glaze melts when it is on fire and creates a glass-like coat on the surface, which deducts the permeability and increases the durability. This acts as a coloring and coating that shines and decorates the piece. There are three basic kinds of glaze: ash, feldspar, and lead. But iron, copper or metal can also be added to the basic ones, creating many different types of glaze.
    Some frequently used glazing techniques are drip glazing, spray glazing, and dip glazing.
  7. 7. Glaze firing Firing at high temperature is carried out after the glazing. The pieces are carefully packed into the kiln to ensure that the temperature inside the kiln does not change.
    Some major types of kilns are climbing kilns, gas kilns, and electric kilns.
  8. 8. Overglaze decoration Figures and patterns are painted on the glaze fired pieces with overglaze decoration brushes.
    There is red painting, colors other than red painting and five-color painting for the overglaze decoration painting techniques. The paints are a mixture of metallic components such as iron, copper, cobalt, or manganese with soda or lead.
    After the delicate lines are drawn, the pieces are sent to firing between 700 and 800℃ (about 1292 to 1472℉), which is lower than the glaze firing to prevent colors from fading.
  9. 9. Finishing After the final firing, the surface of the piece is filed down and it is complete.
