Japanese Chanko Stoneware Tumbler – Kuro-Blue Textured Glaze

This is a handmade Japanese studio pottery tumbler featuring a striking dark kuro (black-blue) textured glaze with a contrasting ice-blue brushed panel. The piece is wheel-thrown from dark stoneware clay and finished with a rich volcanic-style glaze typical of modern Japanese kiln studios. The subtle cratered texture, matte–gloss transitions, and minimalist asymmetric glaze mark are all characteristics associated with contemporary Mashiko and Seto-style studio works, though the square potter’s mark indicates an independent artist rather than a major production kiln.
