Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight grain with occasional wavy or interlocked patterns; noticeable dark brown to black streaks resulting from high mineral content.
Color Description
Heartwood is typically a golden or medium brown, darkening with age and light exposure; sapwood is pale yellowish white. Usually has a dull luster with an oily feel.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; exceptional resistance to rot, termites, and weathering due to high natural oil and rubber content.
Common Uses
Boat building (decks and trim), outdoor furniture, flooring, veneer, cabinetry, and high-end exterior joinery.
Geographic Origin
Native to Southern 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 depending on source and quality.
Wood Age Estimate
The sample appears to be seasoned heartwood with moderate oxidation, likely 5-10 years post-harvest or reclaimed from older stock.
Sustainability Status
IUCN Red List: Endangered (wild populations); however, widely available from FSC-certified sustainable plantations.
Workability
Generally easy to work but contains silica which highly blunts cutting edges; glues and finishes well if surface oils are managed with solvent like acetone.
Notable Features
Distinctive leather-like scent when freshly cut; heavy natural oils give a greasy feel; excellent dimensional stability even in wet conditions.
Finish Recommendations
Teak oil or Danish oil are preferred to enhance natural beauty; clear lacquer or polyurethane can be used if surfaces are pre-cleaned of oils.
Identification Confidence
High; the golden-brown color, characteristic dark streaks, and slightly oily surface texture are hallmark indicators of Tectona grandis.
