Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Generally straight to slightly interlocked with a coarse, uneven texture. The sample shows a flat-sawn appearance with distinct, long grain fibers and some oily surface sheen.
Color Description
Golden to medium brown heartwood that tends to darken with age. Sapwood is a pale yellowish-white. It possesses a natural luster and can develop a characteristic silvery-gray patina if left unfinished outdoors.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable. Renowned for its exceptional resistance to rot, termites, and fungal decay due to high natural oil and rubber content.
Common Uses
Marine decking, outdoor furniture, high-end boat building, flooring, cabinetry, and exterior joinery.
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand); widely grown in plantations across tropical regions of Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$25.00 - $45.00 per board foot, depending on quality and source (e.g., Burmese vs. Plantation Teak).
Wood Age Estimate
The sample appears to be a modern material, likely less than 10-15 years old, based on the uniform surface wear and contemporary application style (possibly flooring or a tabletop).
Sustainability Status
Listed on the IUCN Red List as Endangered due to habitat loss and overexploitation; FSC certification is available for plantation-grown stock. Export of wild-grown teak from Myanmar is heavily restricted.
Workability
Generally easy to work with hand and machine tools, though its high silica content (up to 1.4%) can rapidly dull cutting edges. It glues well if the surface oils are wiped with a solvent first.
Notable Features
Distinctive leather-like odor when freshly cut. High oil content makes it naturally water-resistant. Known for having a somewhat 'greasy' or waxy feel to the touch.
Finish Recommendations
Teak oil or Danish oil to maintain the golden-brown color. Marine-grade varnishes are used for high-moisture environments. Natural finishes are best to avoid peeling due to internal oils.
Identification Confidence
High. The combination of the medium-brown hue, large open pores, visible oiliness, and the specific 'parched' fiber appearance is highly characteristic of Tectona grandis.
