Lu Zhantang - Representative Inheritor of Yao Indigo-dyeing Skill Project in Qiubei County, Wenshan

Biography

Lu Zhantang (陆占堂), male, of the Yao ethnic group, was born in 1945 in Chongge Village (冲革村), Jinping Town (锦屏镇), Qiubei County (丘北县), Wenshan Zhuang and Miao Autonomous Prefecture (文山壮族苗族自治州). He is the representative inheritor of the Yao Indigo Dyeing Technique (瑶族蓝靛制作技艺).

Characteristics of the Indigo Dyeing Technique

Natural Dye

Yao indigo is a pure, natural plant-based dye known for its vibrant color, pleasant fragrance, and antibacterial and mothproof properties. It is primarily used in batik and general fabric dyeing. It is also favored by traditional Chinese painters as a botanical source of indigo pigment.

Complex Craftsmanship

The process of making Yao indigo is intricate and follows precise methods. Indigo plants are typically harvested around August and September when they are lush and have high juice yield and pure color. The process includes:

• Placing fresh indigo plants into a fermentation pit to soak in water until the water turns blue and releases a pleasant indigo scent. The plants are then removed using wooden rakes and sieves to filter the juice.
• Adding powdered quicklime into the pit, stirring vigorously with wooden sticks until green foam rises to the surface.
• Sealing the pit tightly to avoid sun or rain exposure.
• After two days, lime and indigo water undergo sedimentation. The waste water on top is drained, and the semi-solid indigo slurry at the bottom is transferred to a storage pool and left to dry for 3–5 days until it becomes a paste.
• The indigo paste is stored at home for future use. When needed, it is mixed with water and edible alcohol in a dyeing vat.

Inheritance and Innovation

Tradition Passed Down

Lu Zhantang began learning the indigo craft from his father at the age of 15. After five years, he became proficient, with deep experience in both cultivating and processing indigo. He selects high-quality seeds and rotates planting locations to ensure robust growth and high juice yield.

Innovative Improvements

Lu pays close attention to the proportions of lime, soaking time, and intensity of stirring. His produced indigo is smooth and fine in texture, with a vibrant, jewel-like blue hue.

Cultural Significance

The Yao Indigo Dyeing Technique is a product of the Yao people's diligence and wisdom. As a traditional craft passed down for centuries, preserving this technique is vital for developing ethnic craftsmanship and for anthropological and ethnological studies. As a key inheritor, Lu Zhantang not only masters the art but also plays a crucial role in safeguarding this intangible cultural heritage.
