Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight grain with occasional wavy or interlocked patterns; presence of small pith rays and visible longitudinal end-grain checks (shaking) common in large slabs.
Color Description
Heartwood is typically a golden or medium brown color, darkening with age. Sapwood is a pale yellowish-white. It has a dull to moderate luster and an oily feel.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; extremely resistant to decay, termites, and weather due to high natural oil and silica content.
Common Uses
Boat building (decks), outdoor furniture, flooring, veneer, cabinetry, and exterior joinery.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations in Africa, Latin America, and the Caribbean.
Market Value & Sustainability
Estimated Market Value
$30.00 to $50.00 per board foot for high-quality Burmese Teak; plantation teak is slightly less.
Wood Age Estimate
The sample appears recently processed or kiln-dried based on the surface texture and lack of deep oxidation patina, though the tree itself was likely 30-60 years old based on slab width.
Sustainability Status
Not CITES listed; however, natural-grown Teak from Myanmar is subject to trade restrictions in some regions. Plantation-grown Teak is widely available and FSC certified.
Workability
Generally easy to work, but the high silica content has a severe dulling effect on cutting edges. Glues better when surfaces are wiped with a solvent like acetone first to remove surface oils.
Notable Features
Distinctive leather-like scent when freshly cut. It has an naturally oily surface and a high resistance to moisture and rotting.
Finish Recommendations
Teak oil or Danish oil is standard to maintain the natural look; epoxy or polyurethane can be used if the wood is thoroughly degreased first.
Identification Confidence
Medium-High; the golden-brown color, characteristic checks (cracks), oily texture, and typical grain structure are highly indicative of Tectona grandis slabs.
