Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Straight to wavy grain; can sometimes be interlocked. The sample shows a coarse, open-pored texture with a slight oily surface and subtle cathedral grain in areas.
Color Description
Golden to medium brown heartwood that darkens with age. Sapwood is a pale yellowish white. It possesses a dull luster and feels slightly oily to the touch.
Hardness Rating
1,070 lbf (Medium)
Durability Rating
Very Durable; famous for exceptional rot, fungi, and insect resistance due to natural oils.
Common Uses
Boat building (decks), outdoor furniture, exterior construction, flooring, and high-end veneer.
Geographic Origin
Native to Southern Asia (India, Myanmar, Thailand, Laos); widely grown on plantations in Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
Ranges from $25.00 to $45.00 per board foot depending on quality, origin (Burmese vs. Plantation), and width.
Wood Age Estimate
Freshly milled or recently sanded, showing the characteristic golden-brown hue before significant UV darkening/oxidation.
Sustainability Status
IUCN Red List: Endangered (wild populations). Sustainable FSC-certified plantation teak is commonly available.
Workability
Generally easy to work but contains high silica content which dulls cutting edges very quickly. Glues and finishes well despite natural oils if surfaces are pre-cleaned with solvent.
Notable Features
Distinctive leather-like scent when freshly cut. High natural oil and silica content. Excellent dimensional stability making it resistant to warping.
Finish Recommendations
Teak oil or tung oil to maintain natural appearance; clear lacquer or polyurethane can be used if the wood is first wiped with acetone to remove surface oils.
Identification Confidence
High; the large open pores, oily appearance, golden-brown honey color, and 'greasy' texture are hallmark traits of Tectona grandis.
