Ebony, from selected Diospyros species, is one of the most exquisite hardwoods. It is heavy, hard and highly prized for its mostly black or striped heartwood. Predominantly native to tropical regions, striped and black ebony woods are exotic rarities due to their limited distribution. Historically, they were regarded as valuable commodities. The density varies between 0.9 and 1.3 kg/dm³ depending on the variety. The yellow-grey sapwood, which accounts for up to 70 % of the trunk, is considered inferior and is often removed directly at the felling site. Ebony, without visible growth rings, is particularly hard and valuable. It is used in high-quality furniture, art objects and musical instruments. It is worth noting that ebony is on the CITES list of endangered wood species, which regulates its sustainable conservation and trade. During processing, sanding dust is produced which can cause irritation to the skin, eyes and respiratory tract.

Ebony, due to its exquisite properties, presents challenges when it comes to drying. Due to the low initial moisture content, drying is initially moderate, but becomes extremely slow from air-dry to room-dry. High shrinkage values, density and slow internal drying can lead to severe cracks. Sealing or delaying surface drying is advisable for pre-dried parts. In terms of natural durability against wood-destroying fungi and insects, heartwood generally performs very well. The limited quantities and dimensions available are mainly used in arts and crafts, from carvings to wind instruments. In mythology, ebony is often attributed magical properties and is used in the manufacture of magic wands, knitting needles and as a decorative veneer. Snow White’s black hair was legendarily associated with the color of ebony.
