Constructed Vessel, Black-Lustered Silver, Guinomi

Thin plaster boards with corners cut at 45 degrees are laid out one by one in a regular pattern, then assembled tier by tier so that the space of a "sake cup" rises up.
Porcelain slip is poured into the space formed by the assembled plaster boards; once the mold is removed, the shape of the guinomi sake cup is complete.
This guinomi sake cup is built up rationally, based on the open form, one of the simplest shapes among vessels.
It is also designed so that, depending on the setting in which it is used, the interior and exterior take on entirely different expressions and textures.
