Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Straight to slightly wavy or interlocked; coarse, uneven texture with a dull surface luster. Exhibits visible cathedrals and some swirling around small knots as seen in the sample.
Color Description
Heartwood is a golden or medium brown that darkens with age. Sapwood is a pale yellowish-white. The sample shows a honey-gold patina consistent with exposure and minor oxidation.
Hardness Rating
1070 lbf (Medium Hardness)
Durability Rating
Very Durable. Exceptional resistance to rot, fungal decay, and termites due to high natural oil content.
Common Uses
Outdoor furniture, boat building (decks and trim), high-end cabinetry, flooring, and exterior joinery.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations in Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 per board foot depending on grade and origin (FEQ - First European Quality).
Wood Age Estimate
20-40 years. The depth of the amber color and the specific surface oxidation suggest a seasoned piece or a reclaimed furniture surface.
Sustainability Status
Vulnerable (IUCN). Plantation-grown teak is widely available and FSC certified, but old-growth Burmese teak is highly regulated and restricted in many markets.
Workability
Generally easy to work, though high silica content can dull cutting edges rapidly. Glues well despite natural oils if surface is wiped with a solvent like acetone first.
Notable Features
Distinctive leather-like scent when freshly cut. High oil content makes it naturally water-repellent and greasy to the touch. Contains high amounts of silica.
Finish Recommendations
Teak oil or Danish oil to maintain the natural look. If used indoors, lacquer or polyurethane can be used but require degreasing the surface before application.
Identification Confidence
High. The combination of coarse grain, golden-brown hue, presence of natural knots, and the characteristic oily sheen are hallmarks of Tectona grandis.
