Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight grain to occasional wavy or interlocked grain; coarse, uneven texture with a dull surface luster due to natural oils.
Color Description
Heartwood is typically golden or medium brown, darkening with age and light exposure. Sapwood is a pale yellowish-white. Often displays dark streaks.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; exceptional resistance to rot, fungal decay, and termites due to high natural oil and silica content.
Common Uses
Boat building (decks and trim), exterior furniture, high-end flooring, cabinetry, veneer, and turnery.
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
Approximately $25.00 to $45.00 per board foot depending on grade and origin (Burmese teak carries a premium).
Wood Age Estimate
The surface shows moderate oxidation and sanding marks, suggesting it is processed timber likely harvested within the last 5-10 years.
Sustainability Status
Listed on the IUCN Red List as Endangered (native populations); widely available via FSC-certified plantations, but subject to trade restrictions in some regions like Myanmar.
Workability
Generally easy to work with hand and machine tools, though high silica content can cause significant dulling of cutting edges. Glues well despite natural oils if surfaces are pre-cleaned.
Notable Features
Distinctive leather-like scent when freshly cut; high natural oil content gives it a greasy feel; excellent dimensional stability.
Finish Recommendations
Teak oil or Danish oil are preferred to enhance natural color; polyurethane can be used if the wood is wiped with a solvent like acetone first to remove surface oils.
Identification Confidence
High; the combination of golden-brown hue, large open pores, visible natural oils, and texture is characteristic of Tectona grandis.
