Choosing the right leather tannage for your project is a bit like picking the perfect ingredient for a recipe - it can make or break the end result and should be carefully considered. The tanning process isn't just about preserving the hide; it's about giving the leather its personality, its unique traits that will make your project shine. This blog will help you to find the perfect match for your next leather creation.
Types Of Leather Tannage
There are three main ways to tan leather, and each one brings something special to the table.
Vegetable Tanning
Vegetable tanning is a traditional method that has been used for centuries and uses natural tannins from plant sources - such as tree bark, leaves, and fruits - to process the leather. What you can expect from vegetable-tanned leather:
-
A rich, natural aroma
-
Develops a beautiful patina over time, enhancing its aesthetic appeal
-
Environmentally friendly, using biodegradable materials
-
Excellent for tooling and stamping designs, as it takes impressions well
-
If initially firm but mellows with use, becoming more comfortable over time
-
Typically thicker and sturdier, making it ideal for items that require structure
Vegetable-tanned leather is like a fine wine; it improves with age. The more you use it, the more character it develops, making it perfect for items intended to last a lifetime.
Chrome Tanning
Chrome tanning is a modern method developed in the 19th century, which uses chromium salts to tan the leather. Chrome-tanned leather offers several advantages:
-
Soft and flexible from the outset, requiring little to no breaking in (with some exceptions, such as boot leather)
-
Highly water-resistant, making it suitable for various applications
-
Available in a wide range of vibrant colours - if you can envision it, you can likely find it
-
Much quicker to produce than vegetable-tanned leather, which helps keep costs down
-
Resistant to heat, ensuring durability in warm conditions
Chrome-tanned leather is often preferred for contemporary applications due to its versatility and ease of use.
Chrome-Free Tanning
Also known as 'wet white' tanning, this method of tanning avoids the use of chromium whilst still producing leather with similar properties to chrome-tanned options. Here's what you can expect:
-
An environmentally friendly alternative to chrome tanning
-
Soft and pliable from day one, similar to chrome-tanned leather
-
Available in a variety of colours, including light and pastel shades
-
Comparable durability to chrome-tanned leather
-
Frequently used for products designed for sensitive skin
As awareness of environmental issues grows, chrome-free tanning is becoming increasingly popular. It provides many benefits associated with chrome tanning while reducing ecological concerns.

Project Types, Use Cases & Examples
When selecting a tannage for your project, consider these factors:
-
Intended Use
What are you making and how tough does the leather need to be?
-
Style
How do you want it to look? Do you prefer a natural look that ages well or a specific colour etc?
-
Environmental Considerations
How important is sustainability for your product?
-
Budget
What’s your budget? Different tanning processes affect the cost.
-
Practice
Buying expensive, regular line hides and skins to hone your techniques is not cost effective - Visit first and buy cheaper, end of line cuts to experiment. Wait until you’re happy to move on to buying the exact leather you require. The trials/experiments will teach you many different aspects of tannages and will help you make your final decisions going forward.
By thoughtfully considering these aspects, you can select the right leather tannage that not only meets your project's requirements but also aligns with your vision.
Remember, there's no one 'best' leather – it all depends on what you're making. Whether you go for the traditional veg-tan, chrome-tan, or the eco-conscious chrome-free, your choice will make a big difference to how your project turns out.
