Jomon pottery

The most ancient Japanese pottery was made about 14,500 BC, that is the most ancient in the world. (The C14 analysis result of a pottery excavated in northern part of Japan was reported 1999/4).




Do you think, " Pottery was invented somewhere in Asia. Japanese in Jomon period just imitated it. As for the culture/civilization of Japan, they had no originality."? It seems to be wrong. They might have had the most advanced technology in the world.




Unglazed pottery from which water does not leak

I had thought that water must leak when a Jomon pottery was used to boil anything, because it is unglazed. I had thought that such as starch plugs the pore of potery and stops leaking after it was used to cook several times. I had thought that only the designs of Jomon pottery progressed. However the fact differs. I should have praised the technology of inside structure of Jomon pottery. When the pottery is manufactured from "soil", its inside is polished at the middle of drying process to make density high by applying pressure with finger or shell etc. The countermeasure to water leak was set up. The baking method also seems to be devised. As for Jomon pottery, water leak does not break out even the unglazed pottery.

About half of the Jomon pottery are for cooking. If they cooked with leaked pottery, it is unable to heat the temperature of the pottery contents up to 90 degrees C, by the evaporation heat of the moisture. Jomon people tilt all the omniscience on pottery and seem to have manufactured an excellent functional pottery. Is the contemporary ceramic art house able to make the unglazed leakless pottery only with soil and baking method?

Selection of "soil"
Jomon pottery is not made only with clay. Sand or soil having larger particle size is mixed with clay. Actually I dug clay at a cliff near my home, and have bedaubed the clay inside of a furnace to make anti-heat layer. As clay dried, cracks occurred a lot and could not bake. I recalled that@we made garden furnace under the guidance of my mother, when I was in junior high school. We mixed the red soil with clay and applied it inside of furnace, dried, burnt. A culture must be linked like this.

Fine clay must be selected. The mixing soil must be selected too. Mixed clay and soil must be kneaded well, and laid for a determined time. It is resulted by analysis that Jomon pottery excavated in Chiba City contains soils of the different region. It is such a case that the mica is used as soil. Mica can not mine in Chiba City.

Use of lacquer
The lacquered ware is said that its technology was introduced from the continent. But there are the Jomon potteries that are applied lacquer in Japan, The application of lacquer might have begun in Japan. Or, the culture in Japan was discontinued.


In the beginning of Jomon period, the Jomon pottery has sharp bottom shape. It is said that such kinds of pottery were used for storage or boiling. Their bottoms were fixed with stones or buried in the ground to avoid falling. Decoration was very simple.

It prevailed to decorate the surface of pottery with code pattern, as Jomon period went on. We call "Jomon" in Japanese about the pattern of the cord
