Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Usually straight, though occasionally wavy or interlocked. The sample shows a flat-sawn cathedral-like arc with oily, coarse texture and open pores.
Color Description
Heartwood is a golden to medium brown, darkening with age. Sapwood is pale yellowish-white. This sample shows a rich honey-brown patina with darker streaks typical of aged or weathered Teak.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable. Renowned for its superb resistance to rot, decay, and marine-borer insects due to high natural oil content.
Common Uses
Marine applications (boat decks and trim), outdoor furniture, high-end flooring, veneer, and carving.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations throughout tropical regions in Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 per board foot (depending on source and grain quality).
Wood Age Estimate
The sample appears to be from a matured board, likely 10-20 years post-harvest based on the depth of oxidation and the presence of minor surface drying checks and small bore holes.
Sustainability Status
Listed as Endangered on the IUCN Red List due to habitat loss; however, it is widely available from FSC-certified sustainable plantations.
Workability
Generally easy to work, but its high silica content can significantly dull cutting edges. Glues well if surfaces are wiped with a solvent first to remove natural oils.
Notable Features
Distinctive leather-like scent when freshly cut; high natural oil and rubber content; feels slightly greasy to the touch; highly water-resistant.
Finish Recommendations
Teak oil is the traditional choice to maintain color. It can be left unfinished to weather to a silver-grey or sealed with marine-grade varnish for high-gloss protection.
Identification Confidence
Medium-High. The oily surface, characteristic golden-brown color with darker mineral streaks, and visible pore structure are classic indicators of Tectona grandis.
