The earth for the pottery is found in Onta in the mountains. It normally comes in the form of rocks and needs to be ground to a pulver. This is done by the usage of traditional water scoops or mills called kara-usu, which rely purely on the flow of the river. The wooden mills grind the earth into a powder, which is then washed and filtered multiple times to purify the material. It is then dried, sometimes over a large oven.
The village is a tightly-knit community, with families of potters going back generations. The work such as the purification of the earth is done by women, while men are responsible for actually creating the wares. Pieces are never signed by an individual but only with the sign of the Onta village. This is to signify that the production of a single vessel was the combined work of the community, not just one person.
Onta ware traditionally consists of utility vessels such as bowls, plates, and tea cups. The style is most often slipware.
