Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Interlocked and wavy grain with a coarse, uneven texture. The sample shows cathedral arches and significant figure common in larger old-growth or high-quality plantation logs.
Color Description
Golden-brown heartwood with darker chocolate-brown streaks. High natural luster and chatoyance visible under the finish. It typically darkens with age but can bleach to a silvery-gray if left unfinished outdoors.
Hardness Rating
1070 lbf (Medium)
Durability Rating
Very Durable. Exceptional resistance to rot, termites, and fungal decay due to high natural oil and rubber content.
Common Uses
High-end outdoor furniture, boat decking (yachts), flooring, exterior joinery, and decorative veneers.
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand); widely grown in plantations across Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
$30.00 to $45.00 per board foot for high-quality FEQ (First Europe Quality) grade.
Wood Age Estimate
The wood appears to be from a mature tree, likely crafted into this furniture item 5 to 15 years ago, showing stable oxidation beneath a film-forming finish.
Sustainability Status
Listed as Endangered on the IUCN Red List due to native habitat loss; however, it is widely available via FSC-certified plantations.
Workability
Generally good, but the high silica content (up to 1.4%) has a severe dulling effect on cutting edges. Glues well if surface oils are wiped with solvent beforehand.
Notable Features
Distinctive leather-like scent when freshly cut. Contains natural rubber and oils that make it water-resistant and provide a 'waxy' feel to the raw wood.
Finish Recommendations
Teak oil or Danish oil is standard to replenish natural resins. For the film finish shown, a marine-grade spar varnish or UV-resistant polyurethane is recommended for outdoor exposure.
Identification Confidence
High. The characteristic golden-brown hue with dark mineral streaks, prominent large pores, and oily appearance are classic diagnostic features of Tectona grandis.
