For this collaboration, Hara Kenya—one of Japan’s leading designers—worked with Taniguchi Seidosho to create a bowl that showcases the properties of Hanasaka pottery stone, the key component of Kutani porcelain clay. For Hara, design means “determining the essence of a thing and making it visible.” The collaboration revolved around Hara’s conceptualization of Hanasaka pottery stone and Taniguchi Seidosho’s response to Hara’s ideas and requests. Hanasaka pottery stone has a number of unique qualities. When the clay is harvested using water extraction alone, it retains minerals such as iron. These minerals make the clay difficult to shape and result in light grey ceramics with black flecks. Usually, the clay is processed to adjust for these qualities and create the white porcelain typical of Kutani ware. However, for this collaboration, these natural qualities were retained and emphasized to create a vessel with a unique tone and texture.
