Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Usually straight, though occasionally wavy or interlocked. Texture is coarse and uneven with a distinct oily or greasy feel. Large open pores are visible as dark streaks.
Color Description
Heartwood is typically golden or medium brown, darkening with age. Sapwood is a pale yellowish-white. It possesses a dull luster and can exhibit minor chatoyance in high-quality cuts.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable. Exceptional resistance to rot, termites, and weathering due to high natural oil content.
Common Uses
Boat building (decks and trim), high-end outdoor furniture, flooring, veneer, cabinetry, and exterior construction.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations throughout tropical regions in Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 per board foot (Burmese/Old growth) or $15.00 - $25.00 (Plantation-grown).
Wood Age Estimate
The sample appears modern with a commercial finish, likely 5-20 years old. The uniform oxidation suggests it has been indoors and well-maintained.
Sustainability Status
Natural-grown Teak from Myanmar is restricted/CITES regulated; Plantation-grown Teak is widely available and FSC certified.
Workability
Generally easy to work, but the high silica content has a severe dulling effect on cutting edges. Glues well despite natural oils if surfaces are freshly sanded or wiped with solvent.
Notable Features
Distinctive scent resembling leather when freshly cut. Contains high levels of silica and natural oils. Known for its incredible stability and weather resistance.
Finish Recommendations
Teak oil or Danish oil are standard to maintain the natural look; high-quality marine varnish or polyurethane can be used but may require de-oiling the surface with acetone first.
Identification Confidence
High. The large, dark, needle-like pore structures combined with the golden-brown hue and oily surface texture are hallmark characteristics of Tectona grandis.
