Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Straight to slightly wavy grain with coarse, uneven texture. Presence of dark oily streaks and open pores appearing as fine lines or vessels.
Color Description
Heartwood is a golden brown to medium brown. The sample shows signs of oxidation and patina, likely darkening from its original straw-color. High natural luster and potential chatoyance.
Hardness Rating
1,070 lbf (Medium Hardness)
Durability Rating
Very Durable. Exceptional resistance to rot, termites, and weathering due to high natural oil and rubber content.
Common Uses
Marine applications (boat decking), outdoor furniture, high-end indoor cabinetry, flooring, and decorative veneer.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown in plantations across Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 – $50.00 per board foot for high-quality solid lumber.
Wood Age Estimate
20–40 years. Based on the deep, warm amber patina and the style of the milled radius on the cutouts, it appears to be a vintage piece from mid-to-late 20th-century furniture.
Sustainability Status
Near Threatened (IUCN). Naturally grown Teak from Myanmar is subject to trade restrictions; however, FSC-certified plantation Teak is widely available.
Workability
Generally easy to work, though high silica content can dull cutting edges rapidly. Glues well if surface oils are wiped with a solvent (like acetone) before application.
Notable Features
Distinctive leather-like scent when freshly cut. Naturally oily feel. Exceptional dimensional stability (minimal shrinkage). High silica content.
Finish Recommendations
Teak Oil or Danish Oil to enhance natural beauty. Polyurethane can be used if preceded by a thorough degreasing of the surface.
Identification Confidence
High. The combination of color, visible pore structure, oily luster, and the specific application (which appears to be a Danish-style chair back or similar outdoor/high-end furniture) is characteristic of Tectona grandis.
