Teak
Tectona grandis • Hardwood (Exotic/Tropical)
Grain Pattern
Typically straight to slightly wavy with a coarse, uneven texture. Some sections show cathedral patterns and minor interlocked grain. Moderate natural luster.
Color Description
Heartwood is a golden or medium brown, darkening with age to a rich, dark brown. Sapwood is a pale yellowish-white. Often features dark streaks (growth ring markers) and oily appearance.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; highly resistant to rot, termites, and fungal decay. Excellent weathering properties due to high natural oil content.
Common Uses
High-end furniture, boat building (decks), flooring, veneer, exterior construction, and outdoor cabinetry.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations across Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 per board foot depending on source (Burmese vs. Plantation) and grain quality.
Wood Age Estimate
The sample appears to be modern, kiln-dried stock, approximately 2-5 years post-processing based on the uniformity of color and lack of deep oxidation/weathering.
Sustainability Status
Listed on the IUCN Red List as Endangered due to habitat loss; plantation-grown wood is widely available and FSC certified. CITES does not currently list Tectona grandis.
Workability
Generally good, though high silica content can dull blades quickly. Glues well if surface oils are managed (wiping with solvent). Sands easily.
Notable Features
Distinctive leather-like scent when freshly cut. High natural oil and silica content. Naturally water-resistant and dimensionally stable.
Finish Recommendations
Teak oil is standard to maintain color; clear lacquers or polyurethane can be used if surface oils are first cleaned with acetone. Best left unfinished for outdoor use.
Identification Confidence
High. The golden-brown hue, characteristic oily sheen, coarse pore structure, and specific dark streaking are diagnostic of Tectona grandis.
