The deep Bordeaux overglaze (辰砂釉 shinsha-yū \/ cinnabar-red) is finished with a fine iron-fleck speckle and a subtle iridescent shimmer in certain light angles; the interior is fully sealed in glossy black overglaze. The engineered 二層構造 (nisō-kōzō \/ double-wall) air-gap cavity keeps cold drinks cold and warm drinks warm longer than a single-wall cup, and reduces the external condensation that would otherwise wet your hand or your table.\u003c\/p\u003e\n\u003ch3\u003e📐 At a glance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm:\u003c\/strong\u003e Rock cup (ロックカップ) — Japanese double-wall tumbler form, no handle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e φ9.0 cm (3.5″) rim × 9.5 cm (3.7″) height\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity:\u003c\/strong\u003e 300 mL (~10.1 fl oz \/ ~1.27 US cups)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 380 g (~13.4 oz) per cup\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stoneware (陶器 tōki), Mino-yaki lineage — hand-crafted (手造り), not slip-cast\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e 二層構造 (double-wall hollow-insulation cavity between inner and outer walls)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior glaze:\u003c\/strong\u003e 辰砂釉 (shinsha-yū) Bordeaux\/burgundy red with fine iron-fleck speckle + subtle iridescent shimmer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterior glaze:\u003c\/strong\u003e 黒釉 (kuro-yū) glossy black, fully food-sealed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFoot:\u003c\/strong\u003e cream\/buff Mino-clay body exposed at the unglazed foot ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand line:\u003c\/strong\u003e 清風 (Seifu) — “Seifu japan style — Produced by mino”\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade by\u003c\/strong\u003e Tabata Shigemichi \/ Kinshō-gama \/ Awasaka in Gifu Prefecture, Japan, curated by ZenKiln\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGift box:\u003c\/strong\u003e 桐箱 (paulownia kiribako, 115×115×125 mm) — the traditional Japanese gift-presentation box (used for tea-ceremony pieces, named-artist work, and formal gifts)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded:\u003c\/strong\u003e Cup + paulownia kiribako + artist biography card + Japanese care card\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e🎨 The artist — Tabata Shigemichi (田端繁道)\u003c\/h3\u003e\n\u003cp\u003eTabata Shigemichi was born in 1959 in Toki city, Gifu Prefecture — the center of Japan’s Mino-yaki tradition. His father, 金也 (Kin’ya \/ Kinya), founded 金昇窯 (Kinshō-gama) in 1955. Shigemichi joined the family business as the 2nd-generation potter in 1979 and began hand-making (手造り) at the kiln; he has been practicing for ~46 years. His group exhibitions include 名古屋中日ビル (Nagoya Chunichi Building) in 1996 and 東京黒田陶苑「土練人」(Tokyo Kuroda Touen “Tsuchineri-jin” \/ “Clay-Kneaders” group show) in 1997. The artist biography card 「清風の匠」(Seifu no Takumi \/ “Master of Seifu”) is included with this cup as part of the named-artist provenance.\u003c\/p\u003e\n\u003ch3\u003e🔥 What 二層構造 (Double-Wall Hollow-Insulation) means\u003c\/h3\u003e\n\u003cp\u003eThis is not a slip-cast or pressed cup — Tabata throws the inner wall and outer wall, then joins them with a sealed air-gap cavity between. The cavity is closed with a small foot vent (visible at the cup base). The trapped air is a poor heat conductor (just like a vacuum thermos works on the same physics, but here with one wall instead of two and air instead of vacuum).

The tradition encompasses many sub-styles (Shino, Oribe, Setoguro, Yellow Seto, and modern engineered designs like this hollow-insulation piece). Tabata’s Kinshō-gama works within the Mino tradition but with contemporary functional innovation — the hollow-construction rock cup form is a modern engineered piece that uses Mino’s centuries of ceramic knowledge in service of a 21st-century use case.\u003c\/p\u003e\n\u003ch3\u003e🧼 Care\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMicrowave-safe\u003c\/strong\u003e ✅ supplier-confirmed (Japanese care card states 電子レンジ使用可 — for reheating)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDishwasher-safe\u003c\/strong\u003e ✅ supplier-confirmed (Japanese care card states 食洗機使用可)\u003c\/li\u003e\n\u003cli\u003eAvoid sudden temperature changes (e.g. boiling water onto a cold cup, or removing a hot cup from microwave directly onto a cold surface) — the Japanese care card explicitly notes 急激な温度変化はお控え下さい\u003c\/li\u003e\n\u003cli\u003eDo not place directly on open flame (this is a finished drinkware piece, not a donabe)\u003c\/li\u003e\n\u003cli\u003eHand-wash recommended for the longest life of the glaze (despite dishwasher being safe, hand-wash preserves the iron-fleck speckle and iridescent surface)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e🎁 Gift-ready\u003c\/h3\u003e\n\u003cp\u003eArrives in a paulownia 桐箱 (kiribako — light-tone wooden gift box) stamped “Seifu japan style — Produced by mino”, measuring 115×115×125 mm.
