Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight with some wavy or interlocked figure; coarse, uneven texture with a naturally oily surface. Large open pores are visible.
Color Description
Heartwood is a golden or medium brown, darkening with age to a rich deep brown. Sapwood is a pale yellowish white. High luster and slight chatoyance.
Hardness Rating
1070 lbf (Medium)
Durability Rating
Very Durable; exceptionally resistant to rot, termites, and fungal decay due to high natural oil and silica content.
Common Uses
Marine construction (boat decks), outdoor furniture, flooring, veneer, cabinetry, and high-end joinery.
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 depending on grain and origin (Burmese Teak is highest).
Wood Age Estimate
Old-growth or vintage; the deep oxidation, patina, and surface wear suggest the wood is likely over 40-50 years old.
Sustainability Status
IUCN status: Endangered (for native forests). CITES Appendix II (some regions). FSC certification is common for plantation-grown teak.
Workability
Generally good, though high silica content can dull tool edges quickly. Glues well with proper surface preparation (wiping with solvent to remove oils).
Notable Features
Distinctive leather-like scent when freshly cut. High oil content provides natural water resistance. High silica content causes blunting of blades.
Finish Recommendations
Teak oil or Danish oil to maintain natural appearance; solvent-based polyurethane for high-wear areas. Requires degreasing with acetone before gluing or finishing.
Identification Confidence
High; the characteristic golden-brown color, oily tactile quality, large open grain vessels, and typical wear patterns are unique to Tectona grandis.
