Tanbark
Tanbark
Tanbark (pronunciation: /ˈtanˌbärk/) is the bark of certain species of tree, primarily used for tanning hides into leather.
Etymology
The term "tanbark" is derived from the Old English "tannian" (to tan) and "bærce" (bark). The word "tannian" itself is believed to have been borrowed from Medieval Latin "tannāre", which is derived from "tannum" (oak bark), a reference to the use of oak bark in tanning.
Usage
Historically, tanbark was often derived from oak trees, such as the cork oak and the English oak. However, other trees, such as the hemlock, spruce, and mangrove, have also been used for this purpose.
The process of tanning involves soaking hides in a solution made from tanbark. The tannins in the bark help to preserve the hide, preventing it from rotting and making it resistant to water.
