A gray mug glazed to a high gloss over dense Amakusa stone clay, made in Hasami, Japan.

The Hasami Porcelain mug in gloss gray seals that clay body completely under glaze, inside and out, which is why the rim resists chipping and the walls hold an even thickness from base to lip. Pick it up and the weight tells you what it is. The same glaze gives the mug its soft gray sheen and shrugs off the crazing and staining that mark cheaper ceramics after months of hot coffee and dishwasher cycles. It is built to look the same in year five as it does on day one.

Part of a system, not a single piece

Every Hasami piece of the same diameter stacks flush — mugs, bowls, plates, and the wood lid that turns this mug into a covered vessel or a coaster. Start with one and you are starting a set that grows without ever looking mismatched. Microwave- and dishwasher-safe.
