Description

Blue Hour Mug is thrown by hand from iron-rich Jianyang clay and fired in a wood-and-gas kiln for over twelve hours. As the glaze melts, iron crystals rise to the surface and form the midnight pattern you see — no two pieces are ever the same.

Why you'll love it

  • Holds heat — thick walls keep tea warm through a long session.
  • Softens the tea — many tea drinkers find the glaze rounds out the taste of oolong and black tea.
  • One of a kind — the kiln, not a printer, decides the final pattern.

Best for

Oolong, black tea, pu-erh and aged white tea. It also makes a thoughtful gift for a tea friend, a housewarming or a birthday.

Material & craft

  • Body: Jianyang iron-rich clay
  • Glaze: natural mineral glaze, lead-free
  • Firing: ~1300°C, reduction atmosphere

Care

Hand wash with warm water and let it air dry. Avoid the microwave, dishwasher and direct flame. A light film of tea will build up over time and is part of the cup's character.

Questions & Answers

Is this piece handmade?

Yes. It is wheel-thrown, glazed and fired by hand, so the glaze pattern on your piece will differ slightly from the photos.

Is the glaze safe for hot drinks?

The mineral glaze is lead-free and fired above 1300°C. It is safe for tea, coffee and other hot drinks.

How should I care for it?

Rinse with warm water and let it air dry. Avoid the microwave, dishwasher and sudden temperature changes.

Will it arrive safely?

Every order is double-boxed with foam inserts. If anything arrives broken, send us a photo and we will replace it.

    Clean foot ring and a very even lip. You can tell a skilled potter made it.
