Care & Tea Patina Guide

Jian Zhan is made from iron-rich clay and mineral glaze.

High-temperature firing forms iron crystals in the glaze.

Unlike most ceramics, Jian Zhan can change with use.

Regular tea contact may gradually alter the surface over time.

This change is part of its character.

Before using your cup for the first time:

1. Place it in cold water with tea leaves (5–7 g per gallon).

2. Bring to a boil.

3. Simmer for 10 minutes.

4. Let it cool naturally.

5. Rinse with warm water.

6. Dry completely.

Do not use detergent.

⸻

• Rinse with hot water before pouring tea.

• Do not leave tea sitting for long periods.

• Rinse after use.

• Do not use hard brushes.

• Always dry completely.

Moisture is the main cause of oxidation.

⸻

Authentic Jian Zhan contains a high level of iron.

With regular tea use, a thin mineral layer from tea may slowly build on the glaze surface.

Over time, you may notice:

• Deeper tones

• Increased surface luster

• A smoother, warmer appearance

• In some pieces, subtle iridescent effects under light

Patina development varies.

High-iron, surface-crystallized glazes often show changes more clearly and sooner.

Strongly vitrified glazes may develop more slowly.

The type of tea, water quality, and frequency of use also influence the result.

This variability is part of the character of Jian Zhan.

⸻

The glaze contains iron crystals.

Iron may react with moisture and create small brown areas.

This is natural.

It does not affect safety or structure.

Drying the cup after use helps reduce oxidation.

⸻

Use it regularly.

Rinse it after tea.

Dry it well.

Let time and tea do the rest.
