Crackle Glazed Matcha Bowl

Inspired by the quiet beauty of Lake Biwa, this handcrafted bowl by Sei Ishido features an intricate network of delicate crackling along the glaze — reminiscent of ice softly fracturing across a winter lake. Each piece is carefully shaped and finished using kan-nyu, a traditional ceramic technique that intentionally creates fine crack-like patterns beneath the glaze. Kan-nyu occurs naturally when the clay body and glaze cool at different rates during firing, resulting in subtle crazing throughout the surface. Far from a flaw, these patterns are deeply celebrated in Japanese ceramics as a reflection of craftsmanship, imperfection, and the handmade nature of each vessel. With time and use, the bowl will gradually develop its own unique character as tea gently stains the kan-nyu, deepening the texture and creating organic patterns unique to your piece. In Japanese tea culture, this transformation is cherished — a quiet collaboration between artist, vessel, and owner that evolves over years of use. No two bowls are exactly alike. Variations in glaze, texture, and crackling are intentional and make each piece truly one of a kind. Care Hand wash only Handmade in Japan Exclusive to Astrid Tea
