Teak
Tectona grandis • Hardwood
Grain Pattern
Straight to wavy grain; coarse, uneven texture with a naturally oily feel. Contains characteristic darker streaks and occasional interlocked grain.
Color Description
Heartwood is a golden or medium brown, darkening with age. Sapwood is a pale yellowish white. The sample shows typical oxidation and surface darkening due to oil content.
Hardness Rating
1070 lbf (Medium)
Durability Rating
Very Durable; exceptional resistance to rot, termites, and weathering due to high natural oil and silica content.
Common Uses
Boat building, outdoor furniture, decking, high-end cabinetry, flooring, and exterior trim.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations throughout tropical regions in Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$25.00 - $45.00 per board foot depending on grade and source (FEQ - First European Quality).
Wood Age Estimate
The sample appears to be seasoned reclaimed stock or an offcut, showing surface oxidation and manual handling marks consistent with 5-10 years of post-milling age.
Sustainability Status
Large-scale plantation growth exists, but old-growth Burmese teak is highly regulated/restricted. Non-CITES listed but subject to strict importation laws (EUTR/Lacey Act).
Workability
Generally easy to work but high silica content causes moderate to severe dulling of tool edges. Glues well if surface oils are removed with solvent prior to bonding.
Notable Features
Distinctive leather-like scent when freshly cut. Heavy accumulation of natural oils and silica. Highly stable with low shrinkage rates once seasoned.
Finish Recommendations
Teak oil or tung oil to maintain natural appearance; epoxies or lacquers require surface degreasing with acetone/denatured alcohol before application.
Identification Confidence
Medium-High; identified by the characteristic golden-brown hue, oily surface sheen, and coarse grain texture typical of Tectona grandis.
