Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Straight to slightly wavy with an uneven texture; exhibits prominent growth rings in this cross-section (end grain) view. Some interlocked grain may be present in longitudinal surfaces.
Color Description
Heartwood is a mellow golden-brown which will darken and richen to a deep russet or reddish-brown with light exposure. Sapwood is a distinct pale yellowish-white. Surface appears dull here but naturally possesses a medium luster.
Hardness Rating
1,070 lbf (Medium Hardness)
Durability Rating
Very Durable; exceptional resistance to rot, fungal decay, and termites due to high natural oil and silica content. Highly weather-resistant.
Common Uses
Marine applications (boat decking and trim), high-end outdoor furniture, luxury flooring, veneer, joinery, and chemical-resistant lab benches.
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand); widely grown on plantations in Africa, Latin America, and the Caribbean.
Market Value & Sustainability
Estimated Market Value
$25.00 - $45.00 per board foot for high-quality genuine Burman/FEQ teak; plantation teak is slightly lower ($15-$25).
Wood Age Estimate
The physical sample appears to be from a log harvested within the last 5-10 years based on the oxidation state of the end grain. The tree itself appears to have been 20-30 years old based on ring count.
Sustainability Status
Not CITES listed for the species (except for populations in certain regions), but Myanmar teak is currently subject to high trade restrictions. Sustainably managed FSC-certified plantation teak is available.
Workability
Generally easy to work but contains high silica content which dulls steel tools rapidly (carbide-tipped cutters recommended). Glues well if surface oils are wiped with solvent (like acetone) prior to bonding.
Notable Features
Distinctive leather-like odor when freshly cut; greasy/oily feel to the touch; high silica content and natural oils make it the premier choice for outdoor/marine use.
Finish Recommendations
Teak oil or tung oil to maintain the natural color; can be left unfinished to weather to a silvery-grey patina. Lacquer and polyurethane can be difficult due to natural oils.
Identification Confidence
Medium-High. The distinct transition from the dark golden heartwood to the pale sapwood, the ring-porous structure visible in the cross-section, and the characteristic 'waxy' appearance are classic Teak indicators.
