Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight grain with occasional wavy or interlocked patterns; presence of dark mineral streaks and a coarse, uneven texture
Color Description
Heartwood is a golden or medium brown, darkening with age; sapwood is pale yellowish-white. Shows a dull to medium luster and distinct oily feel
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; exceptional resistance to decay, rot, and termites due to high natural oil content
Common Uses
Boat building (decks and trim), outdoor furniture, exterior construction, flooring, and high-end cabinetry
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations in Africa and Latin America
Market Value & Sustainability
Estimated Market Value
$25.00 to $50.00 per board foot depending on source (FEQ - First European Quality)
Wood Age Estimate
The sample appears to be modern dimensional timber with some oxidation, likely 5-15 years post-harvest based on the surface patina
Sustainability Status
Not CITES listed; IUCN status: Endangered (wild populations); widely available from FSC-certified sustainable plantations
Workability
Generally easy to work but high silica content causes severe dulling of cutting edges; glues well despite natural oils if surfaces are freshly prepared
Notable Features
Distinctive leather-like scent when freshly cut; high natural oil and rubber content; extremely stable with low shrinkage rates
Finish Recommendations
Teak oil or Danish oil to maintain natural appearance; can be left unfinished to weather to a silver-gray; clear lacquer if degreased first
Identification Confidence
Medium-High; identifying markers include the characteristic golden-brown hue, dark mineral streaks, and the fuzzy, fibrous tear-out typical of oily tropical hardwoods
