A soft wood with a coarse grain. It resembles oak, and can be used in its place when a quartered effect is not desired. Chestnut is unsuitable for fine details because the grain is coarse and it has marked annual rings. Certain cuts were used in late 18th Century England to imitate satinwood. One form of chestnut, Wormy Chestnut, is popular today.
