I just received this hagi cup today - purchased from Artistic Nippon. The artist is Noutomi Naoko, a daughter of the craftsman Noutomi Susumu. I was drawn to this piece because her carvings remind of fossil impressions in rock. Its beautiful and interesting from every angle, including the bottom. It’s just barely large enough to use as a chawan, and the delicate but uneven rim feels very good against the mouth when sipping matcha.
The photos are from the website.
Yes, makes one imagine drinking tea with cavemen
I would say "the delicate and uneven rim" thinking the unevenness is part of the charm
