20. Mishima-de (Mishima Style)

Mishima-de (also written as Mishima-de) is a technique in which patterns are created by carving or stamping indentations into a clay body rich in iron, and then filling those indentations with white slip (inlay).
*While it is generally written as 'Mishima-de' (三島手), in Hagi ware, it is traditionally written with the character 'Mishima' (見島) after Mishima Island off the coast of Hagi City, as the soil from that island was well-suited for this style.

The origin of Mishima-de lies in Goryeo tea bowls, and it was named 'Mishima-de' because the patterns resembled the characters found in the 'Mishima Calendar' issued by Mishima Taisha Shrine in Shizuoka Prefecture.

Since Hagi ware was introduced from the Goryeo dynasty, it is believed that this technique was naturally incorporated as well.

Note that 'Mishima-de' (見島手) does not refer to items made specifically from Mishima soil, but rather to items produced using the aforementioned Mishima-de technique. Currently, Mishima soil can no longer be mined and is not used; instead, red clay with similar components is used as a substitute, but works created using this technique continue to be called 'Mishima-de'.

Furthermore, in Hagi ware, the general term for items made from soil rich in iron is 'Mishima'.
