Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Straight to slightly wavy grain with a coarse, uneven texture. The sample shows a flat-sawn to rift-sawn orientation with visible open pores and a slightly oily surface appearance.
Color Description
Heartwood is a golden or medium brown, darkening with age and light exposure. Sapwood is typically a pale yellowish-white, though not clearly distinguished in this heartwood-dominant sample. Natural luster is moderate to low.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable. Exceptional resistance to rot, decay, and termites due to high natural oil and rubber content. Highly weather-resistant.
Common Uses
Boat building, outdoor furniture, high-end cabinetry, flooring, veneer, and exterior joinery.
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand); widely grown in plantations across tropical regions in Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 per board foot for high-grade Burmese Teak; Plantation Teak often ranges from $15.00 - $25.00.
Wood Age Estimate
Modern lumber, likely freshly surfaced within the last 5-10 years based on the lack of deep oxidation or graying associated with exterior weathering.
Sustainability Status
Listed on the IUCN Red List as Endangered in native habitats. Plantation-grown Teak is widely available and often FSC certified, though Myanmar Teak is subject to international trade sanctions.
Workability
Generally easy to work with hand and machine tools, but natural silica content has a severe dulling effect on cutting edges. Glues well with surface preparation to remove oils; finishes well.
Notable Features
Distinctive leather-like scent when freshly cut. Heavy natural oils/rubber content give it a greasy feel and make it waterproof. Dust can cause skin or respiratory irritation.
Finish Recommendations
Natural oils (like Teak Oil or Danish Oil) are best to enhance natural appearance. If using polyurethane or lacquer, the wood should be wiped with a solvent like acetone first to remove surface oils.
Identification Confidence
High. The characteristic golden-brown color, visible longitudinal pore streaks, and the apparent waxy/oily surface texture are hallmarks of Tectona grandis.
