Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight to wavy grain with a coarse, uneven texture. Features visible longitudinal streaks and a slight cathedral pattern on the flat-sawn face.
Color Description
Golden to medium brown heartwood that darkens with age. Sapwood is a pale yellowish-white. It possesses a moderate luster and a characteristic oily feel.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable. Exceptional resistance to rot, termites, and weathering due to high natural oil and silica content.
Common Uses
Marine applications (boat decks), outdoor furniture, flooring, veneer, cabinetry, and high-end joinery.
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand); widely grown in plantations across Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 per board foot, depending on grain quality and source.
Wood Age Estimate
The sample shows significant oxidation and surface wear, suggesting the timber was harvested and milled 20-40 years ago, though the furniture piece may be younger.
Sustainability Status
Listed on the IUCN Red List as Endangered due to habitat loss and overexploitation; FSC certification is highly recommended for plantation-grown stock.
Workability
Generally easy to work but high silica content significantly dulls cutting edges. Glues well following surface degreasing; holds screws and nails well.
Notable Features
Distinctive leather-like scent when freshly cut; naturally greasy surface; extremely stable with low shrinkage rates.
Finish Recommendations
Teak oil or Danish oil are preferred to enhance natural color; if using film finishes like lacquer, a sealer is required to block natural oils.
Identification Confidence
High; the combination of large pores, oily surface texture, golden-brown color, and characteristic weathering patterns are definitive for Tectona grandis.
