Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Straight to slightly wavy grain with a coarse, uneven texture. The sample shows a linear, porous grain consistent with plain-sawn or rift-sawn tropical hardwood.
Color Description
Heartwood is typically a golden or medium brown, darkening with age. Sapwood is a pale yellowish-white. It often has a dull luster and a slightly oily feel.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable. Exceptional resistance to rot, termites, and weathering due to high natural oil content.
Common Uses
Boat building (decks and trim), exterior furniture, flooring, cabinetry, veneer, and high-end joinery.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations throughout tropical regions of Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 per board foot
Wood Age Estimate
The sample appears to be modern kiln-dried stock, showing minimal oxidation or UV graying, likely less than 5-10 years since milling.
Sustainability Status
Not listed in CITES Appendices, but listed as Endangered on the IUCN Red List due to a 30% population decline. FSC certification is common for plantation-grown Teak.
Workability
Generally easy to work, though high silica content can dull cutting edges quickly. Glues well and finishes beautifully, though natural oils can occasionally interfere with some surface adhesives.
Notable Features
Distinctive leather-like scent when freshly cut. Naturally oily feel and high silica content contribute to its legendary weather resistance.
Finish Recommendations
Teak oil or Danish oil are preferred to maintain the natural look; high-quality marine varnish or polyurethane if used for heavy-duty outdoor applications.
Identification Confidence
Medium-High. The visible large open pores, prominent growth rings, golden-brown hue, and coarse texture are classic indicators of Tectona grandis, particularly appearing like plantation-grown stock.
