What Is Vegetable Tanned Leather

What Is Vegetable Tanned Leather?

Vegetable-tanned leather is leather tanned using natural tannins found in various plant matter such as tree bark, leaves, and fruits. This traditional eco-friendly method, dating back centuries, results in leather with a unique set of characteristics, including a rich, warm color, a distinctive earthy smell, and the ability to develop a beautiful patina over time.

While often stiffer initially, vegetable-tanned leather becomes more supple with use and is known for its durability and longevity, making it a preferred choice for high-quality goods like bags, wallets, and saddles.

Historical footnote: While we focus on modern tanning methods, it's worth noting the cultural impact of terms like 'Corinthian Leather'—a 1970s marketing term (famously used by Chrysler) that implied luxury, though it described no specific tanning process or origin.

The Vegetable Tanning Process (Step-By-Step)

1. Preparatory Phase (Beamhouse)

Curing and Soaking: Salted and soaked hides to remove impurities and hydrate.
Liming: Loosens hair and opens fibers for tanning.
Fleshing: Removes leftover flesh and fat.
Splitting and De-liming: Adjusts thickness and neutralizes pH.
Pickling: Prepares hides for tannin absorption.

2. Tanning Phase

Preparation of Tannin Solution: Tannins extracted from plants and mixed with water.
Immersion: Hides soaked in tanning baths for weeks or months.
Gradual Strength Increase: Tannin concentration increases gradually.
Monitoring: Skilled tanners oversee the entire process.

3. Post-Tanning Treatments

Pressing and Setting Out: Removes excess water and preps for finishing.
Re-tanning: Optional step to enhance qualities.
Dyeing and Fattening: Adds color and oils for flexibility.
Drying: Carefully dried with or without mechanical softening.
Finishing: Final treatments to achieve desired texture and thickness.

Remember: This slow, meticulous process results in leather that is durable, beautiful, and environmentally conscious.
