Lacquer Finishes on Tuan-Shan: Urushi Layers That Protect and Deepen Handle and Ribs

Lacquer (urushi) is the traditional finish that both protects and deepens the wood of a tuan-shan. Applied in multiple thin layers and polished between coats, urushi seals the bamboo or wood against moisture and handling while building a deep, lustrous surface — a finish that grows richer with age and distinguishes a collectible from a souvenir.

The Scenario: Raw wood needs protection

Lacquer finishing faces three challenges:

Pain Points

• Raw bamboo and wood handles and ribs absorb moisture and crack or warp over time;
• An unfinished surface feels cheap and lacks the depth expected of a fine fan;
• A durable finish must withstand handling without chipping or peeling.

The Solution: Three lacquer finishing solutions

Three practices build a fine lacquer finish:

1. Multiple thin urushi layers Lacquer is built up in thin layers, each cured and polished, for depth and durability.

2. Moisture-sealing protection The cured lacquer seals the wood, preventing the cracking and warping from humidity.

3. A finish that deepens with age Urushi develops a deeper luster over time, distinguishing a collectible from a souvenir.

The Result: A protected, lustrous handle

With a proper lacquer finish, the handle and ribs stay stable and gain a deep, age-rich luster. The fan presents as fine craft and lasts for generations.
