Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Generally straight grain, though it can occasionally be wavy or interlocked. It features a coarse, uneven texture and a naturally oily or greasy feel.
Color Description
Heartwood tends to be a golden or medium brown, darkening with age. Sapwood is a pale yellowish-white. It often shows dark streaks or variegation when freshly cut.
Hardness Rating
1,070 lbf (Medium Hardness)
Durability Rating
Very Durable; extremely resistant to termites, fungal decay, and rot due to high natural oil content. Excellent weather resistance.
Common Uses
Ship and boatbuilding (decking), exterior construction, high-end furniture, veneer, turnings, and carving.
Geographic Origin
Native to southern and southeastern Asia (India, Myanmar, Thailand); widely grown on plantations across tropical regions in Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 to $50.00 per board foot depending on thickness, width, and source (e.g., Burmese vs. Plantation).
Wood Age Estimate
The darker honey-brown patina and subtle surface oxidation suggest this is older stock or reclaimed material, likely several decades old.
Sustainability Status
Not CITES listed, but listed as Endangered on the IUCN Red List due to a population reduction of over 50% in its natural range; FSC certified plantation teak is widely available.
Workability
Generally easy to work with hand and machine tools, but has a high silica content that can rapidly dull cutting edges. Glues can be difficult to bond due to surface oils; solvent wiping is recommended prior to gluing.
Notable Features
Distinctive leather-like scent when freshly worked. Contains high amounts of natural oils and silica. Highly stable with low shrinkage rates.
Finish Recommendations
Teak oil is the traditional choice to maintain the natural look. Lacquers and varnishes can be used but may require a sealer to prevent the natural oils from interfering with the curing process.
Identification Confidence
Medium-High; based on the specific golden-brown hue, visible coarse texture, and the characteristic darkening patterns consistent with aged Tectona grandis.
