Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Generally straight to slightly interlocked grain with a coarse, uneven texture. The sample shows a flat-sawn or cathedral grain orientation with visible growth ring patterns and small knots, common in plantation-grown or second-growth stock.
Color Description
Heartwood is typically a golden or medium brown, darkening with age to a deeper reddish-brown. Sapwood is a pale yellowish-white. This sample shows a warm amber-golden hue with visible lighter streaks and a naturally dull to oily luster.
Hardness Rating
1070 lbf (Medium)
Durability Rating
Very Durable. Renowned for its exceptional resistance to rot, decay, and marine borers due to high natural oil and silica content.
Common Uses
Boat building (decks and trim), high-end outdoor and indoor furniture, exterior construction, flooring, veneer, and turnery.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown in plantations across tropical regions in Africa, Latin America, and Asia.
Market Value & Sustainability
Estimated Market Value
$25.00 to $45.00 per board foot for high-quality lumber; higher for FEQ (First European Quality) Burmese teak.
Wood Age Estimate
The visible surface wear, minor scratching, and oxidation of the finish suggest this is a vintage piece of furniture, likely 30-50 years old.
Sustainability Status
Listed as Endangered on the IUCN Red List due to a population decline of over 50% in its natural range; CITES Appendix II (some populations). FSC-certified plantation teak is the more sustainable alternative.
Workability
Generally easy to work but contains high levels of silica which rapidly dulls cutting edges. Glues well despite oily nature if surfaces are wiped with a solvent like acetone first. Finishes well naturally.
Notable Features
Features a distinct leather-like scent when freshly cut. It contains natural oils that make it water-resistant and give it a greasy feel. Its high silica content provides excellent grip for wet surfaces, like boat decks.
Finish Recommendations
Teak oil or Danish oil is traditionally used to maintain the natural color. If used indoors, a wiping varnish or polyurethane can be applied, though natural oils can occasionally cause adhesion issues.
Identification Confidence
High; the combination of the golden-brown color, large open pores, characteristic cathedral grain, and the visible oily residue within the grain are diagnostic of Tectona grandis.
