About African Blackwood

Botanical name Dalbergia melanoxylon
Family Leguminosae
Local names mpingo, pau preto
English name African blackwood
Distribution The African blackwood tree is widely distributed in a triangle spanning from South Sudan to Angola to the Eastern Cape in South Africa.
The tree It grows as a bush in most places and, in only a few regions, as a sizeable tree – measuring up to 9 meters (30ft.) in height and 30 cm (12 in.) in diameter, or larger. Experts relate this fact to the behaviour of fauna more than to competition from flora.
The wood The heartwood is dark brown with black streaks. This colour usually predominates so that the general effect is nearly black. The narrow sapwood is light yellow and clearly defined. The wood is exceptionally hard and heavy, with a density ab.1.35 t/m3, (79 lb/ft3). The texture is fine and even.
Seasoning It dries very slowly and tends to split during drying, especially in log form. The application of wax or paint on both log ends is advisable to minimise splitting.
Workability It is extremely hard to cut and process. The use of tungsten carbide tools is required.
Use African blackwood is extremely hard and heavy. Makers of woodwind musical instruments prefer it to ebony because of its fine tonal and acoustic features, stability and resistance to saliva. It is also recognised because of its constant density as the best hardwood for ornamentals and turnery of cues, walking sticks, bobbins, butts of sport weapons, cutlery, knives, technical items, pins, spindles, tools and drumsticks.

Restrictions on African blackwood supply

In 2017, all Dalbergia, including the Dalbergia melanoxylon, was added to the Convention on International Trade in Endangered Timber Species (CITES) Appendix 2. Trade in this species in now controlled and subject to certification.

The felling, transport, processing, export and import of this wood is now controlled and subject to certification and permits. The endemic region of northern Mozambique and southern Tanzania has been in a situation of armed conflict for more than three years. Respect for conventions and legislation is therefore utopia that many ignore!

Cabo Delgado, Mozambique’s key supply region and port, has been temporarily taken over by jihadists. Disgruntled young people, with no prospect of progress, took control of the region and expelled the Mozambican government army. The young conscripts do not know the region, the language and above all are not motivated to wage war on behalf of the government of Maputo. The distance between Maputo and Mocimba da Praia, the key port taken and controlled by the jihadists, is 1,700 kilometres.

For 13 years, from 2000 to 2012, we bought and processed African blackwood from Cabo Delgado.

The quality of the logs kept declining. The logs on offer became so bad that we stopped buying. We could still buy African blackwood at a high price. It was only good as firewood!

One of our clients, a French oboe maker, informed us that the delivery, from a well-known German supplier resulted in no less than 70% of the billets having to be rejected as unsuitable for his instruments. Soon after, he closed his business.

We don’t play this game. We have understood that the name and reputation of our company come first.

We have researched, discovered and tested two quality wood species as alternatives for African blackwood for woodwind.

Music industry leaders have recognised mopane as the future of the woodwind industry, at least equivalent to African blackwood for clarinets, oboes, English horns and the like.

The sound profile of mopane wood makes it suitable for classical, jazz and modern music.

The resulting diversity relieves pressure on one type of wood (African blackwood) that may become extinct. It also demonstrates that musical sounds do not need to be uniform – ProSono sees this as a mandate. We want to help to promote tonal and botanical diversity!

Our limited supply of African blackwood does not come from Mozambique or Tanzania.

Our suppliers comply with their local legislation. We obtain CITES import and re-export permits. We maintain total control of the supply chain. The countries in question are at peace, which allows for control and respect for conventions and legislation.

Our sources are, however, limited.

African blackwood compared to common ebony (Diospyros spp)

African blackwood (and mopane and leadwood) are denser than ebony and very much less porous. These species have a higher oil content and so aren’t at risk of splitting due to the acidity of saliva.
