Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Straight grain with a coarse, open-pored texture; occasionally wavy or interlocked in older growth or specific cuts. The visible end grain shows large, distinct pores typical of ring-porous or semi-ring-porous tropical species.
Color Description
Heartwood is typically golden or medium brown, darkening with age. Sapwood is a pale yellowish-white. It possesses a dull to moderate luster and a characteristic oily feel.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; exceptional resistance to decay, termites, and weathering due to high natural oil and silica content.
Common Uses
Boat building (decks and trim), outdoor furniture, high-end flooring, cabinetry, exterior construction, and veneer.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); extensively grown on plantations throughout tropical regions in Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 per board foot for high-quality Burmese Teak; plantation-grown is slightly lower.
Wood Age Estimate
The sample shows significant oxidation and surface wear, suggesting it is likely several decades old (20-40 years) or has been exposed to the elements.
Sustainability Status
Not currently CITES listed, but Myanmar (Burmese) Teak is subject to international trade sanctions and listed as Endangered on the IUCN Red List. FSC-certified plantation teak is available.
Workability
Generally easy to work but contains high levels of silica which dulls cutting edges rapidly. Glues well despite oily nature if surfaces are wiped with solvent (acetone) first.
Notable Features
Distinctive leather-like scent when freshly cut. High natural oil content makes it unique for marine environments. It has a high silica content and can cause skin irritation in some workers.
Finish Recommendations
Best treated with specialized Teak Oil or left unfinished to weather to a silver-grey. If filming finishes like lacquer or polyurethane are used, a sealer is required to prevent the oils from interfering with adhesion.
Identification Confidence
Medium-High; the combination of large vessel pores, golden-brown hue, oily surface texture, and the circular end-grain appearance is highly characteristic of Tectona grandis.
