Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Straight to slightly wavy grain with a coarse, uneven texture and a distinctively oily feel.
Color Description
Heartwood is a golden or medium brown, darkening with age and exposure to light. Sapwood is a pale yellowish-white. Often features dark streaks (mineral streaks) as seen in the sample.
Hardness Rating
1000 - 1150 lbf (Medium)
Durability Rating
Very Durable; exceptional resistance to rot, decay, and termites due to high natural oil and silica content.
Common Uses
Marine construction, boat building (decks and trim), outdoor furniture, high-end cabinetry, flooring, and exterior joinery.
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand); widely grown in plantations across tropical regions in Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$25.00 - $45.00 per board foot depending on source (FEQ - First European Quality) and grain quality.
Wood Age Estimate
The sample appears recently milled from kiln-dried or seasoned stock, showing minimal oxidation or UV graying common in older weathered Teak.
Sustainability Status
Plantation-grown teak is widely available and FSC certified. Old-growth Burmese Teak is restricted due to environmental and political sanctions; listed on the IUCN Red List as Endangered in some natural ranges.
Workability
Generally easy to work with hand and machine tools, but high silica content causes significant dulling of cutting edges. Glues well if surfaces are wiped with solvent to remove surface oils.
Notable Features
Distinctive leather-like scent when freshly cut; high natural oil content gives it a greasy feel; high silica content acts as a natural blade abrasive.
Finish Recommendations
Teak oil or Danish oil is preferred to maintain natural appearance. For marine use, specialized varnishes or high-solids epoxies may be used if the wood is thoroughly degreased with acetone.
Identification Confidence
High; the golden-brown hue with specific dark mineral streaking, coarse open-grain texture, and the characteristic matte/oily luster are classic identifiers for Tectona grandis.
