Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Straight grain with occasional waves; coarse, uneven texture with a distinct oily feel or lackluster appearance due to high silica content.
Color Description
Heartwood is a golden or medium brown that darkens with age; sapwood is a yellowish-white. The sample shows a tawny, golden-brown hue typical of aged teak.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; exceptional resistance to rot, fungal decay, and termites due to high natural oil content.
Common Uses
Outdoor furniture, boat building (decks and trim), high-end cabinetry, flooring, and exterior joinery.
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand); widely grown in plantations across Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$25.00 - $45.00 per board foot
Wood Age Estimate
20-40 years (based on the visible oxidation, patina, and style of the flat panel surface which suggests vintage furniture).
Sustainability Status
Not CITES listed; listed as Endangered on the IUCN Red List due to native habitat loss; FSC certification is widely available for plantation-grown stock.
Workability
Generally easy to work but high silica content causes significant dulling to steel blades; requires carbide-tipped tools. Natural oils can interfere with gluing and finishing.
Notable Features
Distinctive leather-like scent when freshly cut; exceptionally high silica and natural oil content; highly resistant to moisture and weather.
Finish Recommendations
Teak oil or Danish oil to maintain natural appearance; if lacquering or painting, surfaces must be wiped with solvent (acetone) to remove surface oils.
Identification Confidence
Medium-High; the coarse grain, characteristic golden-brown color, and visible oily sheen in the wet/refinishing area are strong indicators of Teak.
