Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight to slightly wavy; usually straight in plantation-grown material. Rough, uneven texture with a dull luster and greasy/oily feel.
Color Description
Heartwood is typically a golden or medium brown, darkening with age. Sapwood is a pale yellowish-white. Often contains dark streaks and experiences significant color shifts after milling (oxidation).
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable. Highly resistant to rot, termites, and weathering due to high natural oil and silica content.
Common Uses
Boat building (decks and trim), outdoor furniture, high-end flooring, veneer, and moisture-prone interior applications.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); extensively cultivated on plantations in Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$25.00 - $45.00 per board foot depending on grade and origin (FEQ Burmese Teak is highest).
Wood Age Estimate
The sample appears modern with a weathered surface patina, suggesting it has been exposed to UV/air for several months to a few years.
Sustainability Status
Not CITES listed; IUCN lists it as Endangered in its native range (Myanmar). FSC and plantation-grown options are widely available and recommended.
Workability
Generally easy to work but high silica content causes rapid dulling of tool edges. Glues can be difficult due to natural oils; surface wiping with solvent may be required.
Notable Features
Distinctive leather-like odor when freshly cut; naturally high oil content makes it uniquely resistant to water and pests.
Finish Recommendations
Teak oil or Danish oil to maintain color. For outdoor use, high-solids spar varnish or simply leaving it unfinished to silver-grey is common.
Identification Confidence
Medium. The oily appearance, uniform coarse texture, and golden-brown hue on the edge grain are characteristic of Tectona grandis.
