Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight, though occasionally wavy or interlocked; medium to coarse texture with a naturally oily feel. Figure is generally subtle but exhibits a distinct linear streaking.
Color Description
Heartwood is typically a golden or medium brown, darkening with age. Sapwood is a pale yellowish-white. It exhibits a dull luster and can have a 'leathery' scent when freshly milled.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; widely considered the gold standard for decay resistance. Extremely resistant to termites, rot, and weathering due to high natural oil and silica content.
Common Uses
Boat building (decks and trim), outdoor furniture, high-end flooring, cabinetry, veneer, and exterior construction.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations across Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 per board foot (varies greatly by region and Burmese vs. Plantation origin)
Wood Age Estimate
5-10 years post-mill; surface shows moderate oxidation and patina consistent with a kiln-dried board that has been stored in a shop environment.
Sustainability Status
IUCN Red List: Endangered (Wild populations); CITES: Not listed, but Burmese Teak is subject to heavy trade sanctions. Plantation-grown Teak is widely available and FSC certified.
Workability
Generally easy to work, but very hard on tool edges due to high silica content. Glues well if surface oils are wiped with solvent (like acetone) prior to bonding.
Notable Features
High natural oil content, distinct leathery odor, high silica content (blunts saw blades), and exceptional dimensional stability even in wet conditions.
Finish Recommendations
Teak oil or Danish oil to maintain natural look; film-building finishes like marine varnish are common for boats but require regular maintenance. No finish is required for outdoor durability.
Identification Confidence
Medium-High; the golden-brown hue, characteristic grain porosity, and 'waxy' appearance of the surface are highly indicative of Tectona grandis.
