Tanned leather is a durable material made from animal hides that have undergone a preservation process called tanning. This process helps prevent decay and makes the leather more flexible and resistant to water. Tanned leather is commonly used in various products, including clothing, shoes, bags, and furniture. There are different types of tanning methods, such as vegetable tanning and chrome tanning, each producing distinct characteristics in the leather. Vegetable tanning uses natural plant materials, while chrome tanning employs chemicals for faster processing. The choice of tanning method affects the leather's color, texture, and overall quality.
