Teak
Tectona grandis • Hardwood / Exotic
Grain Pattern
Generally straight grain with some waviness; coarse, uneven texture with a distinctive oily feel. Flat-sawn appearance showing some subdued cathedral patterns.
Color Description
Heartwood is a golden to medium brown, darkening with age. Sapwood is a pale yellowish-white. It exhibits a dull luster and can have dark streaks.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; exceptional resistance to rot, weathering, and termite attack due to high natural oil content.
Common Uses
Outdoor furniture, boat building (especially decks), flooring, cabinetry, veneer, and high-end joinery.
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand); widely grown on plantations in tropical regions globally.
Market Value & Sustainability
Estimated Market Value
Varies significantly ($15.00 - $40.00 per board foot depending on source and quality).
Wood Age Estimate
Estimated middle-aged (10-20 years for the object) based on surface oxidation, patina development, and minor surface scratches/wear.
Sustainability Status
Natural-grown teak is increasingly rare; plantation teak is widely available and FSC certified sources exist. Not CITES listed but some sources under export bans.
Workability
Fairly easy to work with tools, though high silica content can dull blades rapidly. Glues well if surface oils are wiped with solvent prior to bonding.
Notable Features
Distinctive leather-like scent when freshly cut; exceptionally high silica and natural oil content providing waterproof qualities.
Finish Recommendations
Teak oil or penetrating oils are best to maintain natural appearance; can be left unfinished to age to a silver-grey; film finishes may peel due to surface oils.
Identification Confidence
Medium-High; the golden-brown color, specific grain texture, and the presence of Thai/South Asian script markings on the board strongly suggest Tectona grandis.
