Oak bark tanned leather

Description

Oak bark was once used extensively for tanning, especially in England. The concentration of tannins in oak bark is relatively low (about 14%) and it takes about 6 months of soaking for the tannins to penetrate the skins. The long slow oak tannage process produced a fine grade of leather. Currently, oak bark tannins are blended with other tanning agents for faster processing.
