Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Generally straight to slightly interlocked with a coarse, uneven texture. The sample shows a flat-sawn cathedral pattern with visible fiber tearing from rough surfacing.
Color Description
Heartwood is typically golden or medium brown, darkening with age. Sapwood is a pale yellowish white. This sample shows a weathered, matte presentation with typical medium brown tones.
Hardness Rating
1,070 lbf (Medium Hardness)
Durability Rating
Very Durable; exceptional resistance to rot, termites, and fungal decay due to high natural oil content.
Common Uses
Outdoor furniture, boat building (decks and trim), exterior construction, flooring, and veneer.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations in tropical regions of Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
Ranges from $25.00 to $45.00 per board foot depending on source and quality.
Wood Age Estimate
The surface oxidation and mechanical wear suggest the board is several years at minimum, likely reclaimed or sourced from aged rough-cut stock.
Sustainability Status
Not listed on CITES Appendices, but IUCN Red List classifies it as Endangered due to a population decline of over 50% in native habitats. FSC certification is common for plantation-grown stock.
Workability
Generally easy to work, though high silica content has a severe dulling effect on cutting edges. Glues well despite natural oils if surface is freshly sanded or wiped with solvent.
Notable Features
Distinctive leather-like scent when freshly cut; high natural oil content gives it an oily/greasy feel; excellent dimensional stability.
Finish Recommendations
Teak oil or Danish oil is standard to replenish natural oils; for film finishes like polyurethane, surfaces must be wiped with lacquer thinner to ensure adhesion.
Identification Confidence
Medium-High; the coarse texture, large open pores, golden-brown hue, and visible 'oily' surface characteristic of rough-sawn Tectona grandis are strongly present.
