Redware teapots are famous as typical Tokoname ware, so that one remembers red-brown teapots immediately when one hears the name of Tokoname. It was relatively earlier in the history of Tokoname ceramics that redware was introduced. It was during the period from 1861 to 1864. Tea ware for green tea like teapots had been produced since the early 19th century in Tokoname following the popularity of the custom of green tea drinking from the late Edo era. Typical tea ware during this period was redware produced in China. Mr. Jyumon Sugie and Nikou Kataoka started to make redware for the first time in Tokoname.
Tokoname redware was made by the clay from rice fields which contained lots of iron. This clay gave the ware a rich deep red color. Producing redware drastically changed Tokoname's ceramic industry. Potters who specialize in making redware teapots appeared in addition to those who had made conventional large products such as jars and pots. Important to the development of Tokoname ceramics was a Chinese potter Jin Shi Heng who was invited to teach Chinese teapot making technique to Tokoname potters in 1878. This greatly helped the rapid development of redware teapots. The technique of carving small letters on teapots started from the time Jin Shi Heng came to Tokoname.
Jin Shi Heng's visit extremely influenced not only ceramic making techniques but the craftsmanship which Tokoname's ceramic industry had previously lacked.

A square down-draft kiln with two months

A square down-draft kiln with two fire mouths was invented in the late Meiji era. They were the result of improvements on conventional kiln designs based on the latest European technology. Two fire mouths were made on the each side of the kiln and the entrance at the front. The flames coming from the mouths move up over the partition or bag wall set in the kiln. The two flames collide on the ceiling, and go down to the floor and out to the chimney through the flue.
The sizes of kilns were diverse. The largest one was 19.4m x 6.4m long and the average one was 7.3m x3.9m.
The ceiling has an arch shape. The chimney is built of bricks. This type of kiln rapidly prevailed during the Taisho era. Eighty-six kilns existed in Tokoname in 1929. Coal was used as a fuel in the early days, heavy oil gradually took its place because it was easier to control and it reduced labor costs. However as anti-air pollution laws were tightened, and cheap heavy oil was not able to reach the standards, production costs to buy expensive heavy oil soared, which made these kilns obsolete. Slowly these kilns disappeared.
Ceramic pipes, flower pots, bonsai pots, charcoal braziers, ornaments, jars and pots were fired in square down-draft kilns with two fire mouths.

Pottery and Porcelain

Pottery quite simply is fired clay. Porcelain is made of crushed stones. The firing temperature of porcelain is higher than that of pottery. Porcelain is baked at around 1,300C compared with pottery which require lower temperatures. In Tokoname red clay is fired at about 1,150c and mountain clay about 1.200c.

Craftsman with traditional techniques(Dento-kougeishi)

Dento-kougeishi is a title given to a craftsman designated by the minister of International Trade and Industry Ministry as a person who has excellent traditional techniques. He or she has to be nominated by people who have more than 12 years experience with ceramics in the area producing traditional arts and crafts.

Egoro or Sagger

Egoro is a container for loading kilns which is also known as "Saya". They are used when products don't require to be touched directly by flames. They protect the products from the combustion of wood and coal and from unnecessary color changes. Moreover they are piled up in the kiln allowing for greater kiln efficiency. Egoro is fired many times, subsequently its surface acquires a natural glaze effect. Some of them have an appeal equivalent to ceramic works.

There are various kinds of materials used to make ceramics. Roughly divided, the major kinds are pottery and porcelain. Clay is for pottery, crushed stones for porcelain. In Tokoname crushed stones is used for sanitary ware and construction tiles. On the other hand different types of clay is used according to the products. Some potters make their own original clay mixing many kinds of clays to make their works distinguished. In addition, clay factories produce a wide range of clays, as a result people in the pottery business can buy suitable clays according to their needs.
Today, various types of clays from other pottery areas come to Tokoname, so many clays from all over the country are available here. Material for porcelain products has to be brought to Tokoname from other places. Clay also comes from Seto, Shigaraki and Iga. In the old days each pottery town had one specific and unique type of ceramics due to its original clay, but nowadays it has changed.
