Candlenut

(Aleurites moluccanus)

Common Name(s): Candlenut, kemiri, candleberry, lumbang

Scientific Name: Aleurites moluccanus

Distribution: Primarily Southeast Asia and Pacific Islands; also found throughout tropical regions worldwide

Tree Size: 65-100 ft (20-30 m) tall,

                      2-3 ft (.6-1 m) trunk diameter

Average Dried Weight: 24.5 lbs/ft3 (390 kg/m3)

Specific Gravity (Basic, 12% MC): .33, .39

Janka Hardness: 340 lbf (1,520 N)

Modulus of Rupture: 7,380 lbf/in2 (50.9 MPa)

Elastic Modulus: 1,063,000 lbf/in2 (7.33 GPa)

Crushing Strength: 3,820 lbf/in2 (26.3 MPa)

Shrinkage: Radial: ~3%, Tangential: ~6%,

                        Volumetric: ~9%, T/R Ratio: ~2

Color/Appearance: Heartwood is light brown, with no clear distinction between sapwood and heartwood. Gray or bluish staining is also common.

Grain/Texture: Grain is straight, with a uniform, coarse texture.

Rot Resistance: Rated as non-durable to perishable; poor insect resistance.

Workability: Generally easy to work, though as is the case with very soft woods, care must be taken not to dent or damage it during handling. Also, blue fungal staining can occur if not dried properly.

Odor: No characteristic odor.

Allergies/Toxicity: Although severe reactions are quite uncommon, the sap of candlenut has been reported to cause skin irritation, though it is unclear if the same reaction occurs in the dried wood. See the articles Wood Allergies and Toxicityand Wood Dust Safetyfor more information.

Pricing/Availability: Generally, the wood is too soft and weak to be used for structural applications, and the tree is considered to be more valuable for its nuts than for its lumber. 

Sustainability: This wood species is not listed in the CITES Appendices or on the IUCN Red List of Threatened Species.

Common Uses: Plywood, utility lumber, interior woodwork, paneling, and kitchen utensils. 

Comments: So named for the oil  taken from the tree’s nuts, which was used in lamps. Candlenut is known much more for its edible nuts than its wood, and the tree has been cultivated in numerous tropical regions worldwide. Candlenut goes by almost as many names as there are regions where it is grown.

Identification:

Porosity: diffuse porous (or ring-porous to semi-ring-porous depending on growing conditions)

Arrangement: solitary and radial multiples

Vessels: large to very large, few to very few

Parenchyma: diffuse-in-aggregates

Rays:  narrow; normal spacing

Lookalikes/Substitutes: None.

Notes: This species is generally diffuse porous, though this sample shows a ring porous pattern, possibly due to more temperate growing conditions.
