Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Generally straight to slightly wavy or interlocked grain with a coarse, uneven texture and visible diffuse-porous vessels. Some slight mottling and linear streaking is visible on the face grain.
Color Description
Golden to medium brown heartwood with darker streaks. Sapwood is typically pale yellowish-white. This sample shows a warm golden-brown patina with visible oxidation and darkening characteristic of aged teak exposed to light.
Hardness Rating
1070 lbf (Medium)
Durability Rating
Very Durable. Exceptionally resistant to decay, rot, and termite attack due to high natural oil content and silica.
Common Uses
Boat building (especially decking), high-end outdoor furniture, flooring, veneer, and professional carving.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand); widely grown on plantations across Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$25.00 - $45.00 per board foot depending on grade and origin (FEQ - First European Quality).
Wood Age Estimate
Approximately 30-50 years based on the heavy oxidation, surface patina, and darkening of the natural oils visible in the grain.
Sustainability Status
Natural-grown Tectona grandis is vulnerable; Myanmar teak is subject to strict trade sanctions in many regions. FSC-certified plantation teak is widely available and sustainable.
Workability
Generally easy to work but high silica content significantly dulls cutting edges. Glues well if surface oils are wiped with solvent beforehand. Holds screws and nails well.
Notable Features
Distinctive leather-like scent when freshly cut; greasy or oily feel due to high natural resins; water-resistant; skin sensations/allergens may occur from dust.
Finish Recommendations
Teak oil or tung oil to replenish natural resins. For marine use, high-build varnish or specialized sealers. Can be left unfinished to weather to a silver-gray.
Identification Confidence
High. The golden-brown hue, large open pores, oily surface appearance, and context of the plank width are highly characteristic of aged Teak.
