This vase was made by one of Arakawa Toyozo's main students, Nakayama Naoki whose Shino and Ki-seto works bare the strong influence of the master though the details differentiate master from student and in this case the posture and form are quite different as well and the dragged vertical mark adding definition to the form is not quite as modeled as that of Arakawa. As for the surface there is a nice balance of translucent and dry areas giving glimpse of the clay through the glaze which has a wide array of glassy yellow-green areas and shimmery crystals created by the firing and small ash crystals. At the end of the day whether it is free standing or hanging doesn't affect the simple, even noble form and an appearance that looks like it has traveled from a point in the very distant past.
