EBONY, AFRICAN
Diospyrus spp.
Family: Ebenaceae
including D. crassiflora Hiern.,
and D. piscatoria Gurke.
Other names
Cameroons, Gabon, Kribi, Madagascar, Nigerian ebony, according to origin.
Distribution
Limited range in southern Nigeria, Ghana, Cameroons and Zaire.
The tree
A small to medium-sized tree attaining a height of about 18m and a diameter
of about 0.6m.
The timber
One of the best jet-black varieties is believed to be D. crass/flora. It is
a very heavy timber weighing 1030 kg/m3 when dried. Other species produce
handsome black and brown striped varieties.
Drying
In general African ebony air dries quite readily, but there is a tendency
for surface checks to develop. In small sizes, the timber kiln dries fairly
quickly and well, with little tendency to split or distort.
Durability
Probably very durable.
Working qualities
The black heartwood is inclined to be brittle and is rather hard to work,
and has a considerable dulling effect on cutters which should have their cutting
angle reduced to 20o to avoid picking up when curly grain is present.
It takes a fine polish.
Uses
Turnery, inlaid work, fancy articles, brush backs.
