Ebony is regulated by the Tanzanian government both by
rationing of raw ebony to master carvers and by limiting the export of finished
pieces. Ebony is one of the most difficult woods to carve and
traditionally only master carvers were given the opportunity. Another reason is
the growing scarcity of raw ebony. Tanzania has substantially
limited harvesting and issues very few licenses for cutting ebony trees. The
high cost of material makes it available for only the best to use. The
bark is tan and generally light. the outer wood is a soft white. The
inner portion of the tree is the fine grained, dense, dark colored wood which
has been highly prized for centuries. the color of ebony varies from dark red to
near jet black through a multitude of rich dark shades. The shade of ebony
is determined by genetics, available moisture, mineral content of the soil and
growth rate and the age of the tree. East African ebony is regarded as
superior to that form other sources . The higher altitudes and more arid
climate of inland east Africa result in a slower growth rate and greater density
than the ebony from West Africa and Indonesia. Generally, the darker ebony
is found at the higher altitudes and are older tree. The ebony with more
red tones has its origin at lower altitudes and from soil with a greater iron
content. Tanzania has a larger share of the highest quality ebony trees on
the planet and an intensive replanting program which is more than four decades
old.
