Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Generally straight grain, occasionally wavy or interlocked. The sample shows a prominent cathedral pattern due to flat-sawing, with a coarse, open-pored texture and a characteristic oily feel.
Color Description
Heartwood is a golden to medium brown, darkening with age. Sapwood is pale yellowish-white. It possesses a dull to moderate luster and may exhibit streaking of darker brown or black due to mineral content.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable. Renowned for its exceptional resistance to rot, decay, and marine borers due to high natural oil and silica content.
Common Uses
Boat building (decks and trim), outdoor furniture, high-end interior flooring, cabinetry, veneer, and exterior joinery.
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand, Laos); widely cultivated in plantations across tropical regions in Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 per board foot for high-quality Burmese/old-growth; $15.00 - $25.00 for plantation-grown stock.
Wood Age Estimate
The sample appears relatively fresh or kiln-dried recently, as it retains a vibrant golden-brown color without the silver-gray patina typical of aged exterior teak.
Sustainability Status
Listed as Endangered on the IUCN Red List due to native habitat loss; however, it is widely available through FSC-certified plantations. Myanmar teak is subject to various international trade sanctions.
Workability
Generally easy to work but contains high silica content which rapidly dulls cutting edges. Glues well if surface oils are wiped with solvent (acetone) prior to bonding. Finishes best with oils.
Notable Features
Distinctive leather-like scent when freshly cut. High oil content makes it naturally water-resistant. Dust can be a respiratory irritant.
Finish Recommendations
Teak oil or Danish oil are preferred to enhance natural beauty. For high-wear areas, marine-grade varnish or polyurethane can be used, provided the wood is degreased first.
Identification Confidence
High. The golden-brown hue, large open pores, visible oiliness, and specific cathedral grain structure are hallmark characteristics of Tectona grandis.
