Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight grain with occasional waviness; coarse, uneven texture with a dull surface luster and a characteristically oily feel.
Color Description
Heartwood is typically a golden or medium brown, darkening with age. Sapwood is a pale yellowish white. It often exhibits streaks of dark brown or black when freshly cut.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; extremely resistant to rot, termites, and fungal decay due to high natural oil and silica content.
Common Uses
Boat building (decks and trim), outdoor furniture, high-end exterior joinery, flooring, and veneer.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations in tropical regions of Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 per board foot
Wood Age Estimate
The sample shows significant surface oxidation and accumulation of workshop debris, suggesting the timber was milled several years to a decade ago.
Sustainability Status
Not CITES listed; however, wild Teak is increasingly rare. Plantation-grown Teak is widely available and FSC certified sources should be prioritized.
Workability
Generally easy to work with but has a high silica content that dulls cutting edges quickly. Glues well despite natural oils if surfaces are wiped with solvent beforehand.
Notable Features
Distinctive leather-like scent when freshly cut. High oil content provides natural moisture resistance and a greasy feel to the touch.
Finish Recommendations
Teak oil or Danish oil is standard to maintain the natural look; if film finishes like lacquer or polyurethane are used, a de-waxing shellac or solvent wipe is necessary for adhesion.
Identification Confidence
Medium-High; the coarse, open-pore structure combined with the characteristic golden-brown hue and oily surface texture are strong indicators of Tectona grandis.
