Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Usually straight, though occasionally wavy or interlocked. The sample shows a coarse texture with large open pores typical of flat-sawn teak.
Color Description
Heartwood is typically a golden or medium brown, darkening with age. Sapwood is a pale yellowish-white. It often has a dull luster and feels slightly oily to the touch.
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
Ship and boatbuilding, outdoor furniture, high-end flooring, veneering, and exterior construction.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); extensively grown on plantations throughout tropical regions in Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$25.00 - $40.00 per board foot for high-quality Burmese Teak; Plantation Teak is lower at $15.00 - $20.00.
Wood Age Estimate
The sample appears to be matured architectural wood, likely 20-40 years old based on the deep oxidation and surface wear patterns.
Sustainability Status
Not CITES listed but threatened in some wild ranges. IUCN Red List classifies it as Endangered in native habitats; FSC-certified plantation teak is widely available.
Workability
Generally easy to work, though high silica content can dull blades quickly. Glues well despite natural oils if surfaces are freshly sanded and wiped with solvent.
Notable Features
Distinctive leather-like scent when freshly cut; high natural oil content makes it uniquely water-resistant; can cause skin irritation or respiratory issues in some people.
Finish Recommendations
Teak oil or tung oil are best to preserve the natural look. If film-forming finishes like lacquer or polyurethane are used, the wood must be degreased with acetone first.
Identification Confidence
High. The visible open grain structure, characteristic oily sheen, golden-brown hue, and the presence of vessel lines in the longitudinal plane are classic indicators of Tectona grandis.
