Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight grain with an open, coarse texture; occasionally wavy grain is present. Large pores are visible as dark streaks on the longitudinal surface.
Color Description
Heartwood is a golden or medium brown, darkening with age. Sapwood is a pale yellowish-white. It often shows a dull luster and feels oily to the touch.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable. Exceptional resistance to rot, termites, and weathering due to high natural oil and silica content.
Common Uses
Marine applications (boat building), outdoor furniture, high-end cabinetry, flooring, and exterior joinery.
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand); widely grown on plantations in Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 per board foot depending on source and grade (Burmese vs. Plantation).
Wood Age Estimate
The sample appears to be a used furniture piece showing signs of oxidation and light surface wear, likely 5 to 15 years old since its last finishing.
Sustainability Status
Listed on the IUCN Red List as Endangered in some wild regions; plantation-grown wood is widely available with FSC certification.
Workability
Generally easy to work with hand and machine tools, though the high silica content can dull cutting edges quickly. Glues well following surface degreasing.
Notable Features
Distinctive leather-like scent when freshly cut. Contains high levels of natural rubber and silica, making it extremely water-resistant.
Finish Recommendations
Teak oil or Danish oil to maintain the natural look; requires surface wiping with acetone prior to gluing or film-forming finishes to remove surface oils.
Identification Confidence
High. The visible large pores, golden-brown color with dark mineral streaks, and the characteristic waxy/oily surface texture are classic indicators of Teak.
