Despite its popularity, some people know little or nothing about vegetable-tanned leather; fun fact, you must have invested in such leather products in the past without an iota of knowledge about its refining process. Not to worry, this guide contains everything you should know about vegetable-tanned leather.
What Is Vegetable Tanned Leather?
Vegetable-tanned leather refers to leather that has gone through “vegetable tanning,” which means that the leather has been treated with tannin-rich plant extracts. It is a thick leather characterized by its robust and natural finish – you would find the hide’s natural fibers visible on the finished product.
Thanks to the gentle treatment this leather hide undergoes, it has a soft, comfortable feel and a long lifespan. This type of leather has been used for centuries in making several leather items.
Every leather item crafted from this vegetable-tanned leather has an unmistakable appearance, with distinctive features including its thickness, earthy smell, and silky feel. It is pretty durable and develops a rich-colored patina as it ages.
What is vegetable-tanned leather made of? This type of leather is sourced from the hides of animals, primarily sheep, and cows. Also, you can find various grades of top-grain and full-grain vegetable-tanned leather.
Vegetable Tanned Leather Explained
Tanning is a process of exposing raw animal hides to specific solutions that make them free from bacteria that could cause rot. Kindly note that there are two significant types of tanning; vegetable tanning and chrome tanning.
Vegetable-tanned leather is subjected to a tanning procedure that uses natural plant extracts, while chrome-tanned leather substitutes such natural solution by employing salts (mostly chromium di-sulfate).
Some tree species from which the tanning extracts are sourced include Oak, Willow, Chestnut, Mimosa, Birch, and Catechu. Vegetable-tanned leather goes through a process that occurs in five significant steps.
Sourcing the leather Hides
This step remains the most significant of all since you need the raw animal hide before moving forward to tanning. After the slaughtering of animals, the hides are removed with the aid of special machines.
It is imperative to note that hides are byproducts, and animals are not killed solely for their skins – the hides are often collected from animals slaughtered for food. Now, the sourced leather hide is taken to a section of the slaughterhouse or a separate building known as the “tannery.”
The hair and fats are removed at the tannery using a few simple procedures. However, the rawhide is first salted for preservation purposes. When the leather is not moist and left unsalted, it starts rotting, which leaves the grain destroyed and causes irreparable damage.
After salting, the leather undergoes liming, where the animal skin is soaked in a lime solution for about 24 hours. This solution is quite potent and can quickly burn off the hairs on the animal’s skin.
After that, whatever hairs and fats are left are removed using a metal tool or machine. To lower the leather’s pH level, the hide is now subjected to “rinsing.” The rinsing process involves spraying the de-haired hide with a specific substance.
The “Proper” Tanning
Tanners often blend tannin extracts from plants according to their choice of color, feel, and strength of the final product. In the main tanning, the pre-treated hides are placed in barrels, tubs, or vats and submerged in a solution of the tanning agents and water.
Then, the hide is allowed to soak, and for vegetable tanning, this could take several months. The hide’s physical properties change as it absorbs these tanning agents.
Drying, Hot-stuffing, and Dyeing
Vegetable-tanned leather can be dyed in different colors. However, leather artisans always condition the tanned hide to enhance its natural color. The hide is removed from the tanning solution, waxed and oiled, and then left to dry away from direct heat. Such an action improves the leather’s durability and makes it suppler.
Following a unique procedure, the hide may be hot-stuffed, and this process stuffs the leather core with tallows and waxes that also increases the leather’s durability and leaves a rich color. Once done, dry the hide and stake it to soften it further.
The final step is to seal the leather to help preserve its color for an extended period and protect it from likely damages that could occur due to exposure to the environment. Most leather experts spray refined vegetable-tanned leather with moisture and scratch-resistant solutions to further ensure the piece remains in pristine condition.
Also, the leather gets stretched and trimmed to transform into finished leather products.
Note: This leather can be dyed in several colors, retanned, and even greased (a process termed “fatliquoring”), depending on the final product and the artisan’s choice. You can employ such procedures to make the vegetable-tanned leather colorful, more elastic, and flexible and increase its softness.
History of Vegetable-tanned Leather
Vegetable-tanned leather dates back to the primeval times when humans worked on transforming animal skins into clothing and several other crafts. However, the vegetable tanning procedure is traced to over 5000 years ago. And it is believed to have begun with the Ancient Egyptians.
This tanning method emerged as a result of a man discovering the fantastic results of raw hides having close contact with the leaves, trunks, and barks of trees. Although a conventional process, vegetable tanning is one artisanal skill passed down several generations.
Kindly note that the vegetable tanning procedure underwent several modifications over the years, and the Romans regulated the industry. These orthodox recipes have been modified, and modern vegetable tanning is done with state-of-the-art technologies.
