Made by Shouraku Sasaki an Ustushi (a replica) of a Black Raku ware, glazed Earthenware called "Shichiri" (lit. 'Seven Leagues'). Which is orignally made by Mr Koetsu Honnami who was a great artist and potter as well live din Edo early 17th c. Shouraku Sasaki is the third generation of family artisans at the kiln.
you can remind of Shichiri-ga-hama, 'Seven League' Beach, in the foreground with Mt Fuji seen past the island of Enoshima in the middle-ground
Feeling the textures and asymmetries of surface, this black and rust raku tea bowl is amazing. When while observing the pictorial subtleties of its glaze on a small screen goose bumps!
An unusual combination of hands-on technique and aestheticism came together like Koetsu did in the past.
"Touch with your hands what your eyes suggest" Attila József
"A surprising thing took place some years ago when Raku XIV. (楽, otherwise known as 覚入 Kakunyū, 1918-1980) requested that several museums return to him the collection of tea bowls he had previously lent to them for an unlimited period of time. His reason was the following: Raku tea bowls become ruined if they are not used. Removing a cold and dry Raku from a museum showcase and holding it in one's hands would indeed cause exasperation, especially for those whose fingers and lips have experienced the intimate warmth and wetness of a tea ceremony. Should any readers feel embarrassed, let me remind them of the modern repulsion for touch which Philip Rawson (1924-1995) calls "tactile castration". In fact, I could most easily compare the artistic delight offered by a Raku bowl to that of a sexual encounter; the ritual act of stroking and caressing a human figure. All of this happens in a completely natural way when using a Raku tea bowl - fondling a statue or brushing one's lips to an art object would only give the impression of deviant behaviour. "
