Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight grain with an occasionally interlocked or wavy texture; coarse, uneven texture with a naturally oily feel. Flat-sawn appearance visible on the face.
Color Description
Heartwood is typically a golden or medium brown, darkening with age. Sapwood is a pale yellowish-white. This sample shows typical golden-brown hues with some darker streaks and a duller surface luster common in unfinished stock.
Hardness Rating
1,070 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, high-end flooring, cabinetry, veneer, and exterior 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
$15.00 - $40.00 per board foot depending on origin (FEQ Burmese vs. Plantation) and width.
Wood Age Estimate
Freshly milled or recently surfaced rough lumber (approx. 0-2 years since processing), showing minimal UV oxidation or silvering patina.
Sustainability Status
Listed as Endangered on the IUCN Red List due to a population decline of over 50% in the last three generations. Often available as FSC certified from plantations.
Workability
Generally easy to work but high silica content severe dulle cutters. Glues well if surface oils are wiped with solvent (like acetone) prior to bonding.
Notable Features
Distinctive leather-like scent when freshly cut. High oil content provides natural water resistance. High silica content causes rapid blunting of tool edges.
Finish Recommendations
Teak oil or Danish oil to maintain color; marine-grade varnish for outdoor exposure. Avoid heavy film finishes if the wood is intended for a natural tactile feel.
Identification Confidence
High; the combination of the golden-brown color, the specific coarse grain texture, and the visible oily sheen/darker mineral streaks is characteristic of Tectona grandis.
