Description
A vegetable tannin of the pyrogallol class is extractable from chestnut wood. Chestnut tannin extract has a low pH, low salts content and produces a firm, heavy leather with a pale, reddish color. Chestnut extract is usually mixed with other tannins, such as Quebracho, Mimosa, or myrobalans. Extract from the tree bark, while not used as a tannin, has been used as a dye. Its dark color extracts were used in 19th century Italy and southern France to make an inexpensive fast black dye for silk.
