Yoshihiro Nishiyama Shinogi BowlSubtle, light catching ridges radiate from the center of Nishiyamas glass serving bowl. While manipulating the temperature of his hand blown pieces, the master of katabuki (kata meaning mold and buki meaning blow) experiments with gravity, forging irreplicable signature textural finishes. Care Instructions: Hand wash only. Each piece is individually handmade, and natural variations in color, texture, size and finish are to be expected and celebrated.
