Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Predominantly straight grain with occasional wavy or interlocked patterns. Exhibits a coarse, uneven texture with distinct dark streaks and visible cathedral patterns on flat-sawn surfaces.
Color Description
Heartwood is a golden or medium brown that darkens significantly with age. Sapwood is a pale yellowish-white. The surface often shows a dull luster and contains dark mineral streaks.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable. Exceptional resistance to rot, decay, and termites due to high natural oils and silica content. Excellent weathering characteristics.
Common Uses
Marine construction, boat building (especially decks), furniture (especially outdoor/mid-century modern), flooring, veneer, and small turned objects.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations in tropical regions across Africa, Asia, and Latin America.
Market Value & Sustainability
Estimated Market Value
$25.00 - $50.00 per board foot for high-quality genuine Burmese Teak; Plantation-grown is slightly lower.
Wood Age Estimate
Based on the uniform patina and typical construction style, this appears to be seasoned timber, likely utilized in furniture aged between 20-50 years (consistent with Mid-Century Modern styling).
Sustainability Status
Listed on the IUCN Red List as Endangered (natural forests). Not CITES listed, but trade from certain regions (like Myanmar) is heavily regulated or sanctioned. FSC certified sources are available.
Workability
Generally easy to work with hand and machine tools, but high silica content has a significant dulling effect on cutting edges. Glues well despite natural oils if surfaces are freshly prepared.
Notable Features
Distinctive leather-like scent when freshly cut. Naturally oily feel. High silica content provides slip resistance in marine applications but dulls blades quickly.
Finish Recommendations
Teak oil is the most common finish to maintain the natural look. Lacquer and varnish can be used but may require a dewaxed shellac sealer or solvent wipe to ensure adhesion to oily surfaces.
Identification Confidence
High. The characteristic golden-brown color, dark streaks, coarse grain texture, and visible oiliness are definitive markers for Tectona grandis, particularly in a furniture context.
