Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Straight grain with a coarse, uneven texture and a naturally oily feel. Flat-sawn cathedral patterns are visible, though the surface shows significant weathering and checking.
Color Description
Heartwood is typically golden or medium brown, darkening with age. Due to weathering and UV exposure, this sample shows significant graying/silvering and a 'bleached' surface appearance, typical of aged outdoor teak.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable. High resistance to termites and specialized rot resistance due to high natural oil and silica content.
Common Uses
Outdoor furniture, boat building (decks), exterior joinery, flooring, and high-end cabinetry.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations across Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
Ranges from $25.00 to $45.00 per board foot depending on source and grade (FEQ grade).
Wood Age Estimate
10-20 years of exposure. The deep checking, oxidation, and silver-gray patina suggest long-term outdoor use without recent maintenance.
Sustainability Status
Native populations in Myanmar are increasingly restricted (CITES-like concerns), but FSC-certified plantation teak is widely available and sustainable.
Workability
Generally easy to work, though the high silica content can dull cutting edges rapidly. It glues reasonably well despite the oily nature if the surface is wiped with a solvent first.
Notable Features
Distinctive leather-like scent when freshly cut; exceptionally oily feel; high silica content and excellent dimensional stability.
Finish Recommendations
Teak oil or penetrating sealers are recommended to restore color. If left for outdoor aesthetics, it can be left unfinished to maintain the silver patina.
Identification Confidence
Medium. The oily grain, specific weathering pattern (silvering and longitudinal checking), and visible pore structure are highly characteristic of aged Tectona grandis.
