Color/Appearance: Heartwood color can vary, ranging from a pale golden yellow to a deeper reddish brown. Color tends to darken to a golden brown over time. Yellow sapwood is well demarcated from heartwood. Overall, Burma Padauk’s color tends to be less red and more subdued than African Padauk.
Grain/Texture: Grain is usually interlocked, with a coarse texture and fairly large and open pores.
Endgrain: Diffuse-porous; large pores in no specific arrangement; solitary and radial multiples of 2-3; mineral deposits occasionally present; growth rings indistinct; rays not visible without lens; parenchyma diffuse-in-aggregates, aliform (winged), confluent, and banded.
Rot Resistance: Rated as very durable regrading decay resistance, with good resistance to termites and other insects.
Odor: Padauk has a faint aromatic scent while being worked.
Allergies/Toxicity: Although severe reactions are quite uncommon, Burma Padauk has been reported as a sensitizer. Usually most common reactions simply include eye, skin, and respiratory irritation. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.
Pricing/Availability: Available much less often than African Padauk, Burma Padauk is likely to be in the mid to upper range for an imported hardwood.
Sustainability: This wood species is not listed in the CITES Appendices or on the IUCN Red List of Threatened Species.
Common Uses: Veneer, flooring, turned objects, musical instruments, furniture, tool handles, and other small specialty wood objects.
Comments: Burma Padauk is the heaviest and hardest of all types of Padauk (Pterocarpus genus) commercially available. The color tends to be a bit more subdued than the more common African variety.
