Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Generally straight grain, though occasionally wavy or interlocked. The texture is coarse and uneven with a dull luster and a distinct oily feel. Some mineral streaks may be present.
Color Description
Heartwood is typically a golden or medium brown, darkening with age and light exposure to a richer deep brown. Sapwood is a pale yellowish-white and clearly demarcated from heartwood.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable. Teak is renowned for its exceptional decay resistance and is highly resistant to rot, fungi, and termites due to its high natural oil and silica content.
Common Uses
Ship and boatbuilding (especially decks), outdoor furniture, high-end interior flooring, cabinetry, joinery, and turnings.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations throughout tropical regions in Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
High; typically ranges from $30.00 to $50.00 per board foot depending on grain quality (FEQ - First European Quality) and origin (Burmese vs. Plantation).
Wood Age Estimate
The sample appears to be seasoned lumber with significant surface oxidation and accumulated dust/residue, suggesting it has been stored in a workshop environment for 5-15 years.
Sustainability Status
Listed on the IUCN Red List as Endangered due to habitat loss and overexploitation. Burmese Teak is subject to various international trade sanctions; FSC-certified plantation teak is the preferred sustainable alternative.
Workability
Generally easy to work, but the high silica content has a significant blunting effect on tool edges. Glues and finishes well, though the natural oils may require wiping with a solvent (like acetone) prior to bonding.
Notable Features
Distinctive leather-like odor when freshly cut; naturally high oil content makes it excellent for wet environments; high silica content and relatively high weight.
Finish Recommendations
Teak oil or penetrating sealers are most common to maintain the natural feel. For high-wear areas, marine-grade spar varnish or polyurethane can be used, provided the surface is pre-treated to remove surface oils.
Identification Confidence
Medium-High. The visible coarse texture, medium brown color with characteristic streaking, and the presence of fine surface checking/patina are highly indicative of Tectona grandis, commonly found in workshop settings for marine or outdoor repair.
