Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight to slightly wavy; simple flat-sawn cathedral pattern is visible in the center section with a coarse, open-pored texture typical of tropical hardwoods.
Color Description
Heartwood is typically golden or medium brown, darkening with age. This sample shows significant surface graying and weathering (oxidized patina) consistent with outdoor exposure, but retains a warm brown hue in saturated areas.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; extremely resistant to rot, termites, and fungal decay due to high natural oil content.
Common Uses
Outdoor furniture, boat building (decks), exterior joinery, flooring, and carving.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations across Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 per board foot (High value due to demand and import costs).
Wood Age Estimate
20-40 years since harvest; surface oxidation and silvery-gray weathering suggest this piece has been exposed to the elements for several years.
Sustainability Status
Listed as Endangered on the IUCN Red List (wild populations); however, much commercial teak is now plantation-grown (FSC certified available).
Workability
Generally easy to work but contains high levels of silica which dulls cutting edges rapidly. High oil content can make gluing difficult; surface wiping with solvent is often required.
Notable Features
Distinctive leather-like scent when freshly cut; exceptionally high silica and natural oil content providing moisture resistance; greasy feel to the touch.
Finish Recommendations
Teak oil or penetrating marine oils are preferred to maintain the natural color; film-forming finishes like polyurethane may peel due to natural oils.
Identification Confidence
Medium-High; the combination of large vessel pores, golden-brown color beneath weathering, and the context of a board that appears to be from outdoor decking or furniture strongly indicates Teak.
