The tanning is transformation of the putrescible skin into a new material, impermeable, flexible and low hydrated: the leather. It consists in treating the “raw” skin by tannins or tanning materials to transform it in leather.
There are several kind of tanning: vegetal, mineral or using chrome.
The vegetal tanning is a skin maceration process in a bath of vegetal tannin or in a bed of tan (crushed barks of oaks arranged in a successive layers) in tanks or special pits. The process is divided in three essentials steps: the swelling, the penetration and the setting. During the vegetal tanning, the swelling operation impacts the leather quality.
The vegetal tannins are mainly barks (oaks, pine, willow), won (chestnut tree, oak tree), roots (Badan) and leaves (Sumac).
