How to Care for Your Tenmoku Cup: The Simple Guide to Lasting Beauty

A genuine handmade Jian Zhan cup is built to last a lifetime. Like any fine craft object, a little thoughtful care goes a long way. Here's everything you need to know.

Season Your Cup First

Before using your new Jian Zhan cup for the first time, season it — a traditional practice that improves performance and helps the glaze absorb the essence of tea over time.

1. Fill the cup with boiling water and let it sit for 2–3 minutes, then discard
2. Repeat once more
3. Brew your first cup of tea normally — ideally a green tea or light oolong

Daily Use: Simple Habits That Protect Your Cup

Do: Rinse with Hot Water Before Each Use

This warms the cup so your tea stays at the right temperature longer, and reopens the micro-pores in the glaze.

Do: Handle with Both Hands

Traditional tea ceremony practice. This distributes heat evenly and reduces the risk of dropping the cup.

Don't: Use Soap

Soap residue can be absorbed into the pores of the unglazed base and subtly alter the taste of your tea. Rinse thoroughly with hot water and wipe clean with a soft cloth — this is sufficient for daily use.

Don't: Put It in the Dishwasher

Harsh detergents and high-pressure water jets can damage the glaze and strip the cup's natural seasoning. Always hand wash.

Deep Cleaning (Monthly or Quarterly)

1. Make a paste of baking soda and water
2. Apply gently with a soft cloth in circular motions
3. Rinse thoroughly with hot water
4. Re-season with a hot rinse and a light brew before next use

The Changing Color Over Time

As the clay absorbs tea, the unglazed base gradually darkens. The glaze may develop a subtle sheen or patina. This is called "raising the cup" (yang bei) in Chinese tea culture — a sign of a well-loved cup. A highly "raised" cup carries the history of every tea session within it.
