Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight grain with a coarse, open-pore texture; some slight waviness is present in this panel indicative of flat-sawn milling.
Color Description
Golden-brown heartwood with a distinct warm glow; sapwood is pale yellowish white (not visible here). The wood darkens with age and exposure to light, eventually turning a silver-gray if left unfinished outdoors.
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
Marine applications (boat decking), outdoor furniture, high-end cabinetry, window frames, and flooring.
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
$40.00 - $65.00 per board foot for high-quality FEQ (First European Quality) grade.
Wood Age Estimate
The sample appears to be from modern millwork (5-20 years old) based on the consistent surface finish and lack of deep oxidation or mechanical wear.
Sustainability Status
IUCN Red List: Endangered (wild populations); however, it is widely available as FSC-certified plantation-grown timber.
Workability
Generally works well, but high silica content has a severe dulling effect on tool edges; glues and finishes can be difficult due to natural oils.
Notable Features
Distinctive leather-like scent when freshly cut; oily or greasy feel to the touch; high water resistance.
Finish Recommendations
Teak oil or tung oil are best to maintain natural appearance; if lacquering, a solvent wipe is required to remove surface oils for proper adhesion.
Identification Confidence
High; the combination of the golden-brown hue, large open pores, oily luster, and typical application in architectural panels is characteristic of Tectona grandis.
