  • Average Dried Weight: 38 lbs/ft3 (605 kg/m3)
  • Specific Gravity (Basic, 12% MC): .59, .60
  • Janka Hardness: 1,360 lbf (6,050 N)
  • Modulus of Rupture: 14,250 lbf/in2 (98.2 MPa)

  • Color/Appearance: Heartwood color can vary widely from a lighter golden brown, to a darker reddish or purplish brown. Colors tend to become more subdued with age.
  • Grain/Texture: Grain is straight to interlocked. Medium to coarse texture with a low natural luster.
  • Endgrain: Diffuse-porous; large pores in no specific arrangement, very few; solitary and radial multiples of 2-3; mineral deposits occasionally present; growth rings indistinct; narrow rays not visible without lens, spacing close; parenchyma diffuse-in-aggregates, winged, confluent, and banded (not marginal).
  • Rot Resistance: Heartwood is rated as being durable to moderately durable; good resistance to insect attack.
  • Workability: Generally easy to work with tools, though if there is interlocked grain present, it may tearout during planing operations. Moderate blunting effect on cutters. Glues, stains, and finishes well.
  • Odor: Has a mild, aromatic scent while being worked.

  • Comments: Sometimes sold under its South African name Kiaat, this wood is actually closely related to the much more well-known African Padauk (Pterocarpus soyauxii). And, much like other species in the Pterocarpus genus, Muninga has outstanding stability, and should remain quite stable in the midst of seasonal changes

Average Dried Weight: 60 lbs/ft3 (955 kg/m3)

Specific Gravity (Basic, 12% MC): .81, .96

Janka Hardness: 2,480 lbf (11,010 N)

Modulus of Rupture: 14,890 lbf/in2 (102.7 MPa)

Elastic Modulus: 1,487,000 lbf/in2 (9.08 GPa)

Shrinkage: Radial: 2.8%, Tangential: 5.4%, Volumetric: 8.2%, T/R Ratio: 1.9

Color/Appearance: Color ranges from a golden brown to a darker reddish brown, often with black streaks throughout. Pale yellow sapwood sharply demarcated from heartwood. Occasionally figured pieces will be seen with subtle mottled grain patterns.

Grain/Texture: Tambootie has a straight grain (though occasionally it can be wavy) with a fine, even texture. Natural oils within the wood help give it a high natural luster.

Endgrain: Diffuse-porous; medium pores in no specific arrangement, moderately numerous to numerous; commonly in radial multiples of 2-4; heartwood gum deposits occasionally present; narrow rays not visible even with hand lens, spacing close; parenchyma generally not visible with hand lens.

Rot Resistance: Tambootie heartwood is rated as being very durable, and is also resistant to insect attack.

Odor: Tambootie has a lingering scent that’s been described as sweet and pleasing, though it is also quite strong.

Common Uses: Carvings, furniture, turned objects, and other small, specialty wood items.

Comments: Tambootie is prized in Africa as a decorative hardwood, used for luxury furniture and other high end applications. It’s frequently used as a substitute for Sandalwood (which is a vague term that may encompass any number of aromatic wood species in Africa and Asia).

Tambootie is one of the few woods that ought to really be handled and worked with care, regardless of a person’s allergic resistance to other woods—its toxicity is well-known throughout its native range

PAU-ROSA – Patchini – Nake “Berchemia zeyheri”

product / By

Pau Rosa

Common Name(s): Pink Ivory, Red Ivorywood

Scientific Name: Berchemia zeyheri

Distribution: Southern Africa

Tree Size: 100-130 ft (30-40 m) tall, 3-5 ft (1-1.5 m) trunk diameter

Average Dried Weight: 65 lbs/ft3 (1,035 kg/m3)

Specific Gravity (Basic, 12% MC): .90, 1.04

Janka Hardness: 3,230 lbf (14,370 N)

Modulus of Rupture: 20,020 lbf/in2 (138.1 MPa)

Elastic Modulus: 2,193,000 lbf/in2 (15.12 GPa)

Crushing Strength: 11,630 lbf/in2 (80.2 MPa)

Shrinkage: Radial: 4.8%, Tangential: 7.2%, Volumetric: 12.1%, T/R Ratio: 1.5

Color/Appearance: Pink Ivory ranges in color from a pale brownish pink, to a bright, almost neon pink, to a deep red. Typically the most valuable pieces of Pink Ivory are a vibrant  pink. Pink Ivory can commonly be seen with a curly or fiddleback grain pattern, further enhancing its visual impact. Sapwood of Pink Ivory tends to be pale yellow to light brown, with a somewhat gradual demarcation from heartwood. Color changes in Pink Ivory (becoming faded or dull over time) can be problematic and are not fully understood.

Grain/Texture: Grain is straight to interlocked; fine, even texture with good natural luster.

Endgrain: Diffuse-porous; medium pores in no specific arrangement, nuymerous; commonly in radial multiples of 2-4; gum/heartwood deposits common, though not easily seen with lens; growth rings may be distinct due to increased pore frequency in earlywood; narrow to medium rays visible without lens; parenchyma not visible with lens.

Rot Resistance: Rated as durable to very durable regarding decay resistance, Pink Ivory is said to have excellent weathering characteristics: though it is seldom used in applications where this would be an issue.

Workability: Pink Ivory has a pronounced blunting effect on cutting edges, and it’s fairly difficult to work in board form. Tearout can occur on figured or quartersawn sections during planing. Pink Ivory is much more common in applications involving carving or turning, and it turns and finishes well.

Odor: Pink Ivory has a distinct and somewhat unpleasant odor when being worked.

Common Uses: Carving, veneers, inlay, knife handles, billiard cues, chessmen, and other turned objects.

Comments: Pink Ivory trees are said to be both rare and valuable, and have been rumored to be “rarer than diamonds.” Other reports state that the tree is relatively common in some areas of South Africa—though large trees with straight, defect-free trunks are much more scarce. According to folklore, the tree is considered sacred to the Zulus in South Africa and is reserved for royalty.

PAU- PRETO Eviko – Mpingo – Mico “Dalbergia melanoxylon”

product / By

Pau Preto

  • Common Name(s): African blackwood, mpingo (Swahili), grenadilla
  • Scientific Name: Dalbergia melanoxylon
  • Distribution: Dry savanna regions of central and southern Africa
  • Tree Size: 20-30 ft (6-9 m) tall, 2-3 ft (.6-1.0 m) trunk diameter
  • Average Dried Weight: 79 lbs/ft3 (1,270 kg/m3)
  • Specific Gravity (Basic, 12% MC): 1.08, 1.27
  • Janka Hardness: 3,670 lbf (16,320 N)
  • Modulus of Rupture: 30,970 lbf/in2(213.6 MPa)
  • Elastic Modulus: 2,603,000 lbf/in2(17.95 GPa)
  • Crushing Strength: 10,570 lbf/in2(72.9 MPa)
  • Shrinkage: Radial: 2.9%, Tangential: 4.8%,
  • Volumetric: 7.7%, T/R Ratio: 1.7
  • Color/Appearance: Often completely black, with little or no discernible grain. Occasionally slightly lighter, with a dark brown or purplish hue. The pale yellow sapwood is usually very thin, and is clearly demarcated from the darker heartwood.
  • Grain/Texture: Grain is typically straight; fine, even
  • texture and good natural luster.
  • Rot Resistance: Heartwood is rated as very durable in regards to decay resistance, though only moderately resistant to insects/borers. The lighter colored sapwood is commonly attacked by powder-post beetles and other borers.
  • Odor: African blackwood has a mild—though distinctive—scent while being worked.
  • Common Uses: Musical instruments (guitars, clarinets, oboes, etc.), inlay, carving, tool handles, and other turned objects.
  • Comments: To be considered the original ebony, African Blackwood was imported and used in Ancient Egypt thousands of years ago. Even the name “ebony” has an Egyptian derivation as “hbny”—which has been shown to refer to primarily to Dalbergia melanoxylon, rather than the species which are considered to be ebony today: such as those in the Diospyros genus. In addition, African blackwood is technically in the Rosewood genus (Dalbergia), and is more stable and resistant to movement and warping than other types of ebony.
  • African blackwood is considered to be among the hardest and densest of woods in the world; indeed, among some 285 species tested, (including Lignum Vitae), Gabriel Janka originally found African Blackwood to be the very hardest. Unfortunately, many online sources list African blackwood’s Janka hardness at only ~1700lbf—which seems very unlikely given its confirmed specific gravity.
