Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Straight to wavy grain with a coarse, uneven texture. The sample shows a flat-sawn face with visible open pores and some slight interlocking grain characteristics.
Color Description
Heartwood is typically a golden or medium brown, darkening with age. Sapwood is a pale yellowish-white. This sample shows a weathered, matte golden-brown with characteristic dark streaks and some green/gray surface oxidation.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable. High resistance to termites, rot, and fungi due to high natural oil content. Extremely weather-resistant.
Common Uses
Marine applications (boat decks/trim), high-end outdoor furniture, flooring, veneer, and exterior construction.
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand); widely grown on plantations in Africa and the Americas.
Market Value & Sustainability
Estimated Market Value
$30.00 to $45.00 per board foot for high-quality FEQ (First Europe Quality) grade.
Wood Age Estimate
Based on the oxidation, the darkened pores, and the presence of an old rusted nail, this wood is likely salvaged or reclaimed, estimated at 20-40 years old.
Sustainability Status
Monitored. Not listed in CITES Appendices, but listed as Endangered on the IUCN Red List due to native habitat loss; FSC-certified plantation teak is commonly available.
Workability
Generally easy to work but contains high silica content which can severely dull cutting edges. Glues well despite natural oils if surface is wiped with a solvent first.
Notable Features
Distinctive leather-like scent when freshly cut. High natural oil and silica content. Feels slightly oily or greasy to the touch.
Finish Recommendations
Teak oil or Danish oil is best to maintain natural appearance. If gluing or film-finishing, surface must be cleaned with acetone to remove surface oils.
Identification Confidence
High. The visible open grain structure, characteristic golden-brown color with dark mineral streaks, and the reaction to the metal fastener (oxidation) are classic indicators of Teak.
