Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Principally straight grain with occasional wavy or interlocked patterns. The sample shows a flat-sawn cathedral appearance with visible mineral streaks and characteristic dark oily streaks.
Color Description
Heartwood is typically golden or medium brown, darkening with age. The sample exhibits a rich honey-brown hue with reddish undertones and visible dark grain lines. High natural luster and a slightly waxy/oily surface appearance.
Hardness Rating
1000 to 1155 lbf (Medium Hardness)
Durability Rating
Very Durable. Exceptional resistance to rot, fungal decay, and termites due to high natural oil and rubber content.
Common Uses
Marine decking, outdoor furniture, high-end cabinetry, boat building, flooring, and decorative veneer.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown in plantations across tropical regions of Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 per board foot for high-quality, old-growth or FEQ (First European Quality) grade.
Wood Age Estimate
Likely several decades old based on the depth of the patina, oxidation of the natural oils, and the wear visible around the machined cut-outs.
Sustainability Status
Not CITES listed; however, native Burmese Teak is subject to international trade sanctions and conservation concerns. FSC-certified plantation teak is widely available.
Workability
Generally good to work with, though the high silica content (up to 1.4%) has a severe dulling effect on cutting edges. Glues well only after surface oils are wiped with a solvent.
Notable Features
Distinctive leather-like scent when freshly cut. High oil content provides natural weatherproofing. Feels slightly greasy or waxy to the touch.
Finish Recommendations
Teak oil or tung oil are preferred to maintain natural beauty. If film-forming finishes like lacquer are used, the wood must be degreased with acetone first.
Identification Confidence
High. The combination of the golden-brown color, dark mineral streaks, prominent large pores, and the characteristic oily sheen are hallmarks of Tectona grandis.
