1 Raku-yaki tea bowl, with Raku mark on the back 2 Oribe-yaki tea bowl 3 Tea bowl with writing These were purchased about 50 years ago when my mother was learning tea ceremony. Items 1 and 2 are unused. The one with writing has been used. They are a great deal as a set. How about them for tea practice? The Raku tea bowl has a gray glaze, and the photo appears bluer than it actually is.
