Hōzan Kiln Hagi Yaki Tea Set

The crackle pattern, known as kannyu, is a hallmark of Hagi Yaki pottery. It occurs naturally during the cooling process due to the difference in contraction rates between the clay body and the glaze, creating a unique, organic texture that evolves as tea oils seep into the fissures over time.

No, these vintage pieces require gentle hand washing. Because Hagi Yaki is porous and features a delicate crackle glaze, harsh detergents and the high heat of a dishwasher can damage the material or cause the glaze to flake.

The split-foot base, or warikodai, is a traditional Hagi Yaki technique where a small notch is carved into the foot ring of the vessel. It is a sign of authentic craftsmanship and helps prevent the cup from sticking to a lacquer tray or table surface.

Hagi Yaki clay is highly porous and retains heat well, making it excellent for keeping tea warm. Because the clay is slightly absorbent, the cups will develop a unique patina and subtle tea aroma over years of consistent use, effectively 'seasoning' the vessels to your preferred brew.

While they are beautiful enough for display, they are fully functional vessels designed for daily use. Just be aware that because of their porous nature, they will change appearance over time as they absorb the tannins from your tea, which is considered a desirable trait in Japanese tea culture.
