Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Typically straight to slightly interlocked grain with a coarse, uneven texture. The sample shows a flat-sawn face with some mild waviness around knots. Large, open pores are clearly visible as dark streaks along the grain.
Color Description
Golden to medium brown heartwood with dark streaks. Surface has a dull luster and feels slightly oily. The wood tends to darken over time into a rich, darker brown when exposed to light.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable. Highly resistant to rot, termites, and fungal decay due to high natural oil content and silica. It is considered one of the most durable woods for outdoor use.
Common Uses
Boat building (decks and trim), high-end outdoor furniture, flooring, cabinetry, veneer, and general exterior construction.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); extensively grown on plantations in tropical regions across Africa, Asia, and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 to $45.00 per board foot for high-quality Burmese Teak; slightly lower for plantation-grown varieties.
Wood Age Estimate
Modern sample, likely less than 5 years old. Surface oxidation is minimal, suggesting it has been recently milled or kept indoors.
Sustainability Status
IUCN Red List: Endangered (as of 1998, though widely farmed). Plantation-grown Teak is commonly FSC certified, but old-growth/Burmese Teak is subject to heavy trade restrictions and CITES concerns.
Workability
Generally easy to work but contains high levels of silica which dulls cutting edges very quickly. Glues well only after surface oils are wiped with solvent. Generally finishes well.
Notable Features
Distinctive leather-like scent when freshly cut. Waxy/oily feel to the touch. High silica content provides excellent slip-resistance for boat decks.
Finish Recommendations
Teak oil or Danish oil is standard to replenish natural oils. For interior use, lacquer or polyurethane can be used, but surface must be wiped with acetone first to remove surface oils for proper adhesion.
Identification Confidence
High. The golden-brown color, characteristic large open-pore structure, oily surface appearance, and presence of typical dark streaks are hallmark indicators of Tectona grandis.
