Description
Deciduous trees of the genus Castanea, native to temperate zones in the United States, Europe, northern Africa and parts of Asia. The American chestnut, Castanea dentata, and the European chestnut, Castanea sativa, produce a light reddish brown wood that is relatively weak with a coarse grain. It is a soft light wood that splits easily but does not turn well. It is used for general construction, framing, fencing, poles and barrels. Chestnut wood was commonly used for painted panels, especially in Italy (Gettens and Stout 1966). Chestnut wood is also widely used to extract a vegetable tannin of the pyrogallol class. It has a low pH, low salts content, and produces a firm leather with a pale, reddish color. The extract from the bark of the chestnut tree 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.
