Hagi Yakiware Tea Cup

Hagi Yakiware is a traditional Japanese pottery style originating from the Yamaguchi Prefecture. It is celebrated for its soft, earthy texture and a unique glaze that tends to change color and character over time as tea oils seep into the porous clay, creating a personalized patina.

The clay used in Hagi pottery is naturally porous and generally has lower thermal conductivity than porcelain, which helps it stay comfortable to hold. However, if you pour boiling water directly into the cup, it will be quite hot; we recommend letting your tea steep for a moment or holding the cup near the rim where it cools slightly faster.

Because this is authentic, porous pottery, it is best to hand wash it with warm water and mild soap. Avoid the dishwasher, as the high heat and harsh detergents can damage the glaze or cause the clay to crack over time.

Yes, due to the porous nature of Hagi clay, the cup will absorb tea tannins over time. This is considered a desirable trait in Japanese tea culture, as it allows the cup to 'season' and develop a unique character that reflects the teas you drink most often.

We do not recommend using this cup in the microwave. The porous clay can trap moisture, which may expand rapidly when heated, potentially leading to cracking or structural damage.
