Teak
Tectona grandis • Hardwood / Exotic
Grain Pattern
Straight grain with occasional wavy or interlocked patterns; medium-coarse, uneven texture with a distinctively oily feel.
Color Description
Heartwood is a golden or medium brown, darkening with age. Sapwood is pale yellowish-white. It often exhibits dark streaks and a dulling luster due to high mineral content.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; excellent resistance to rot, termites, and weathering due to high natural oil and silica content.
Common Uses
Boat building (decks and trim), outdoor furniture, exterior construction, flooring, veneer, and high-end cabinetry.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand, Laos); widely grown on plantations in Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
Approximately $25.00 to $45.00 per board foot depending on grade and origin (FEQ - First European Quality).
Wood Age Estimate
Post-harvest age appears to be 10-30 years based on surface oxidation and the weathered, rough-sawn patina of the board.
Sustainability Status
Listed on the IUCN Red List as Endangered in native habitats; however, it is widely available through FSC-certified plantations.
Workability
Generally easy to work but high silica content (up to 1.4%) has a severe dulling effect on cutting edges; glues and finishes well despite natural oils if surface is wiped with solvent.
Notable Features
Distinctive leather-like scent when freshly cut; exceptionally high silica and oil content makes it one of the world's most weather-resistant woods.
Finish Recommendations
Teak oil or tung oil to maintain color; marine-grade varnish for outdoor use; shellac or lacquer works if pre-cleaned with acetone to remove surface oils.
Identification Confidence
Medium-High. The combination of the golden-brown hue, coarse/fibrous grain texture, and characteristic 'greasy' appearance on the rough-sawn face is highly indicative of Tectona grandis.
