Teak
Tectona grandis • Exotic/Tropical (Hardwood)
Grain Pattern
Straight to slightly wavy with a flat-sawn cathedral pattern visible on the face; coarse texture with a slightly oily feel.
Color Description
Golden to medium brown, darkening with age to a rich, darker brown. Sapwood is typically pale yellowish-white, though not visible here. Exhibits moderate luster.
Hardness Rating
1,070 lbf (Medium Hardness)
Durability Rating
Very Durable; exceptional resistance to rot, termites, and weathering due to high natural oil content.
Common Uses
Boat building (decks and trim), high-end outdoor furniture, flooring, veneer, cabinetry, and exterior joinery.
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand, Laos); 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 source (Burmese vs. Plantation) and grade.
Wood Age Estimate
The board shows signs of modern processing but exhibits surface patina suggesting it has been aired or stored for 5-10 years.
Sustainability Status
Natural-grown Teak is increasingly restricted; listed in the IUCN Red List as Endangered in some regions. FSC-certified plantation teak is available.
Workability
Generally easy to work with hand and machine tools, though its high silica content (up to 1.4%) has a significant dulling effect on cutting edges.
Notable Features
Distinctive leather-like scent when freshly cut; exceptionally high natural oil content provides self-lubricating properties and water resistance.
Finish Recommendations
Teak oil or Danish oil are preferred to enhance natural beauty. Polyurethane can be difficult due to oils; surface must be wiped with solvent (acetone) before gluing or film-finishing.
Identification Confidence
High; the distinct cathedral grain structure combined with the characteristic golden-brown hue and oily sheen is typical of Tectona grandis.
