Know Your Wood: Ebony

Ebony
I've aspired more than once to build a board that looked like this, but it never worked out this well!

Common trade names: Gaboon Ebony, African Ebony, Cameroon Ebony, Nigerian Ebony.

Genus: Diospyros crassiflora

Janka Hardness (pounds-force): 3220

Description: Very hard to work. Quite heavy and dense. None more black. The Ironbarks, by their colorfully marketable names, are used quite a bit in outdoor applications in their native Austrialia. *There is some ambiguity to the specific scientific properties of this species. In any event, there is consensus that this species is extremely dense and hard.

Location: Africa. (Distributed/farmed in Oceania and SE Asia additionally.)

Common Aliases: Kanran, Kayu malam, Kribi ebony, Kurkuo, Mgriti, Msuini, Nyareti, Omenowa, Trayung

Performance: A very durable, high oil content wood. Ebony can be difficult to glue, due to this oily nature. Ebony is resistant to many insects. Will dull cutting blades quickly.

Common Uses: Works of art, fine carvings, chess pieces, piano flats/sharps, pool cues, other ornamental pieces.
About as densely darkened as wood comes without artificial dying.

  1. If you are looking for durable and well furnished furniture then I must say you have to prefer furniture made up of Ebony wood. I have bought quality furniture for my home in which African Ebony wood has used. It gives classic look and brightens up the worth of my home.
