A vegetable tannin of the pyrogallol class is extractable with hot water from chestnut wood (13.4%) and bark (6.8%). Chestnut tannin extract has a low pH and low salts, but high acids and high sugar content. It produces a firm, heavy leather with a pale, reddish color. Chestnut extract is usually mixed with other tannins, such as Quebracho, Mimosa, or myrobalans. The dark color extracts from the tree bark has been used as a dye in 19th century Italy and southern France to make an inexpensive fast black dye for silk.
