{"product_id":"p7913","title":"Kuroshuten","description":"This is a new black sake cup by Tomoyuki Oiwa, who studied ceramic techniques under Ryuichi Kakurezaki and is currently dedicated to his research in Kamigori, Hyogo Prefecture.\u003cbr\u003e\n\u003cbr\u003e\nThis latest work was removed from the kiln in October 2025.\u003cbr\u003e\n\u003cbr\u003e\nDue to Mr. Oiwa's intense firing process, the black slip has achieved a vivid color, resulting in a glossy, clear black similar to the black works of his mentor, Mr. Kakurezaki.\u003cbr\u003e\n\u003cbr\u003e\nMr. Oiwa places particular importance on the firing time during the final high-temperature stage of the kiln process, and by carefully firing the piece for a relatively long period at near-maximum temperatures, he brings out a brilliant blue kiln transformation (yohen).\u003cbr\u003e\n\u003cbr\u003e\nA beautiful cobalt blue spreads across the entire outer perimeter of the piece, excluding the front, the foot, and the interior, and it will surely shimmer even more beautifully when it absorbs the moisture of sake during use.\u003cbr\u003e\n\u003cbr\u003e\nThe black slip on the foot and the interior has also been fired thoroughly, transforming into a black color with a luster as if it were wet.\u003cbr\u003e\n\u003cbr\u003e\nThe bold form, which makes heavy use of *shinogi* (faceted) carving, creates fine ridges and grooves in the clay surface, and the translucent light blue kiln transformation gains delicate shading through these irregularities.\u003cbr\u003e\n\u003cbr\u003e\nThe design, which incorporates and outputs his mentor's tripod style, is also fascinating, and Mr. Oiwa's meticulous attention to detail is evident from the foot to the rim of the vessel.\n\nSigned wooden box to follow (we apologize, but it will take some time before shipping.)\u003cbr\u003e\nDiameter 7.9cm x 7.3cm x Height 6.3cm\n\nTomoyuki Oiwa was born in Kobe, Hyogo Prefecture, in 1977.\u003cbr\u003e\n\u003cbr\u003e\nHe completed his studies at the Bizen Pottery Center in 2004 and became a student of Ryuichi Kakurezaki in 2005.\u003cbr\u003e\n\u003cbr\u003e\nHe established his own studio in Hyogo Prefecture in 2014.","brand":"大岩智之","offers":[{"title":"Default Title","offer_id":46618213744737,"sku":"7913","price":24200.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0654\/9916\/8865\/files\/7913.jpg?v=1790233460","url":"https:\/\/www.tourakuen.jp\/en\/products\/p7913","provider":"川口陶楽苑","version":"1.0","type":"link"}
