The difference between Chrome-tanned and Vegetable tanned leather
Today, we're talking about leathers—specifically, veg tan leather vs. chrome tanned leather. We'll talk about the characteristics of each type of leather, how they differ, and why one might be picked over another, depending on the application.
We'll start with some definitions. A chrome-tanned leather is simply leather treated with chromium salts to give it a reddish-brown colour. This process creates a durable, water-resistant finish that makes chrome-tanned quality leather ideal for outdoor use, including boots, luggage, and jackets.
Vegetable tanned leathers are made by treating animal skin with natural substances like tree bark, lichen, fungi, algae, etc., which gives the leather a light brown colour. These leathers, such as upholstery and handbags, are typically used indoors.
Let's look at the differences between the two types of leather.
First, let's talk about the differences between chrome tanned leather and veg tanned leather.
A chrome-tanned leather is made by applying chromium salts to animal hides. Chromium is a metallic element found naturally in the earth's crust. It is commonly used in products ranging from stainless steel to automobile parts.
The main difference between chrome tanned leathers and veg tanned ones is how they are processed. Veggie-tanned leathers are produced by soaking the rawhide in a solution containing various natural extracts, while chrome-tanned leathers are dyed before finishing.
Veg & Chrome Tanned Leathers
The invention of chrome tanning in 1840 changed everything we think about leather. So when you look at a pair of shoes today, chances are good that they're made of vegetable-tanned leather. But if you look more intimate, you'll notice something else in those shoes besides leather - chrome. In fact, without chrome, leather wouldn't even exist.
Chrome tanning is the process of treating hides with a solution containing chromium salts. This produces a durable finish that lasts longer and resists water better than traditional vegetable tannage. So why did people switch over to chrome tanning? Well, it turns out that chrome tanning offers some pretty significant advantages over vegetable tanning.
For one thing, chrome tanning gives us a much thicker, stronger and more flexible leather. And unlike vegetable tanning, chrome tanning doesn't require soaking the hide in a chemical bath, making it faster and easier. Another advantage is that chrome tanning requires less energy than vegetable tanning.
But perhaps the most important reason to use chrome tanning is that it allows us to produce various colours. While vegetable tanning limits our options to browns and black, chrome tanning lets us make reds, blues, greens and yellows.
Examples of Vegetable-Tanned Leather
The vegetable-tanning process is a type of leather that is made using a process that involves soaking the hide in water molecules. This process allows the hide to retain its natural shape and form, making it more durable and resistant to water damage.
Veg-tanned leather is often used to produce high-quality leather boots, belts, and other accessories. It is also commonly used in making upholstery due to its durability and water-resistant properties.
The vegetable tanning process gives leather goods a unique look and feels different from other types of leather. This distinctive quality makes veg tanned leather a popular choice for those who want to create unique and stylish products.
The history of vegetable-tanned leather dates back thousands of years ago. Ancient Egyptians and Romans used different plants to extract tannic acid mixed with animal skin to make leather. Even though this ancient technique wasn't very efficient, it did work well enough to sustain human life during those times.
In the Middle Ages, tannins extracted from grape skins were used to treat wounds and prevent infection. Then, during the Renaissance, people began experimenting with different plants to create a similar substance. By the 1800s, scientists discovered that oak bark could be used to extract tannins.
Today, most vegetable-tanned leather is produced using oak bark and chestnut extracts. These two substances are often combined with synthetic chemicals to enhance the finished product's colour, softness, durability, and water resistance.
Examples of Chrome-Tanned Leather
As the name suggests, chrome-tanned leather is tanned using chromium salts. This type of leather is distinguished by its high resistance to water and other liquids, making it ideal for various applications. Here are a few examples of products that commonly use chrome-tanned leather:
Automotive upholstery: Chrome-tanned leather is often used in the upholstery of high-end automobiles because of its durability and luxurious appearance.
Furniture: Leather sofas and chairs made with chrome-tanned leather are built to last, withstanding years of use without displaying signs of wear and tear.
Footwear: Chrome-tanned leather is also commonly used in footwear construction, especially dress shoes and leather boots that need a polished look.
Advantages & Disadvantages
There are two primary types of leather tanning: vegetable and chrome. Both have advantages and disadvantages that must be considered when deciding which type of leather to use for a project.
Vegetable tanning is the older of the two methods and results in a more durable, natural-looking leather. It is also eco-friendly, using tannins derived from tree bark and other plants. However, it is slower than chrome tanning, and the finished product is more expensive.
Chrome tanning is faster and cheaper than vegetable tanning, but it is less eco-friendly as it uses chromium sulphate, a chemical that can harm the environment. Chrome-tanned leather is also not as durable as vegetable-tanned leather and does not develop the same rich patina over time.
The Leather Tanning Process for chrome -Tanned Leather
Chrome-tanned leather is one of the most popular types of leather used today. The tanning process for this type of leather is quite simple and only requires a few steps.
First, the hide must be soaked in a solution that contains chromium salts. This helps to soften the hide and prepare it for the tanning process. Next, the hide is placed in a tanned drum using the chemical solution chromium sulphate. This helps to maintain the hide and give it its characteristic chrome-like colour. Finally, the hide is dried and then finished with a protective coating.
The entire method usually takes about two weeks to complete. Chrome leather is known for its strength and durability, making it ideal for various applications.
The Leather Tanning Process for vegetable -Tanned Leather
Vegetable tanning is a traditional, natural way to tan leather. The process uses tree bark and other plant organic materials to create vegetable tannins, preserving the hides. This method is environmentally friendly and produces beautiful, durable leather.
The first step in the vegetable tanning method is to soak the hides in a solution of tannin-rich tree bark. This can take several days or weeks, depending on the thickness of the hide. Once the hide has absorbed enough natural tannin, it is removed from the solution and placed in drums, where it is slowly rotated for several hours. This helps to distribute the tannins throughout the hide evenly.
After rotating in the drum, the hide is placed in a press where it is squeezed of any excess moisture. Once it has been pressed, it is hung up to dry.
What Are Veg & Chrome Tanned Leathers Best For?
Veg-tanned leathers are usually used for shoes, bags, leather wallets, belts, etc., while chrome-tanned leathers are mostly found on cars, furniture, and upholstery. Both types of leather are durable, water resistant, and long-lasting. However, they differ in how they're processed.
The process involves soaking the hides in vegetable oils like soybean or coconut oil for veg-tanned products. This allows the leather to breathe and absorb moisture without cracking. As such, veg-tans are generally lighter weight than chrome-tans. As an outcome, they also tend to feel softer.
On the flip side, chrome-tanned leathers require exposing the hide to the chemical solution of chromium salts to make it hard and strong. This makes them heavier and denser than veg-tans. Plus, most of the chrome tans are blackened. So, they look darker, prosperous, stronger, and more professional.
How Can You Tell The Difference?
There are many ways to identify whether a piece of leather is veg tanned or chromed, including smelling it, burning it, and even testing its colour and water molecules' beautiful patina. But some things can make it easier to determine if the leather quality is veg tanned or chrome tanned. We've covered you if you're interested in learning how to tell the difference.
Conclusion – Veg Tanned vs. Chrome Tanned: Which is Better?
In this article, we are peeking into the difference between veg tanning and chrome tanning. We are comparing both methods and trying to find out what is better for us. The most important thing about leather is that it must be tanning leather properly. If you do not treat it correctly, it could become damaged. So, let's start our comparison.
What Is Best For You?
As you see above, both ways are good for making leather soft and supple, but one way is better than the other, depending on your needs. For example, if you plan to use leather for outdoor activities, you might choose chrome tanning because it lasts longer and keeps its shape. On the other hand, if you plan to wear leather for indoor purposes, veg tanning is recommended.
