Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight, though occasionally wavy or interlocked; characterized by a coarse, uneven texture and a slightly oily or greasy feel
Color Description
Heartwood is typically a golden or medium brown, darkening with age. Sapwood is a pale yellowish-white. Often features dark streaks and a dull luster
Hardness Rating
1070 lbf (Medium)
Durability Rating
Very Durable; exceptional resistance to rot, fungal decay, and termites due to high natural oil content
Common Uses
Ship and boatbuilding (decks), exterior construction, high-end furniture, veneer, turnings, and carving
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations in Africa and Latin America
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 per board foot depending on thickness and origin (Burmese vs. Plantation)
Wood Age Estimate
Modern cut (less than 10 years source-to-sample), showing typical kiln-dried oxidation levels
Sustainability Status
IUCN Red List: Endangered (wild populations); however, much is available through FSC-certified plantations
Workability
Generally easy to work, though the high silica content can have a severe dulling effect on cutting edges; glues well despite natural oils if surfaces are pre-cleaned
Notable Features
Distinctive leather-like scent when freshly milled; high silica and natural oil content contribute to its legendary weather resistance
Finish Recommendations
Teak oil or Danish oil to maintain natural appearance; epoxies or lacquers require solvent-wiping (acetone) beforehand to ensure adhesion
Identification Confidence
Medium-High; the golden-brown color, coarse open grain, and visual evidence of oily resins are highly diagnostic of Tectona grandis
