Teak
Tectona grandis • Exotic/Tropical
Grain Pattern
Generally straight to slightly wavy grain with a coarse, uneven texture. The sample shows a prominent cathedral figure on the flat-sawn face with visible open pores.
Color Description
Heartwood is typically a golden or medium brown, darkening with age. Sapwood is a pale yellowish-white. It possesses a dull luster and a characteristic oily feel.
Hardness Rating
1,070 lbf (Medium Hardness)
Durability Rating
Very Durable; excellent resistance to rot, termites, and fungal decay. High silica and oil content provide exceptional weather resistance.
Common Uses
Boat building (decks and trim), outdoor furniture, high-end cabinetry, flooring, and exterior joinery.
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand); widely grown on plantations across Africa and Latin America.
Market Value & Sustainability
Estimated Market Value
Approximately $30.00 to $50.00 per board foot depending on source and quality.
Wood Age Estimate
Relatively modern stock (less than 10 years old) based on the fresh milling marks, lack of deep oxidation/patina, and consistent color across the board face.
Sustainability Status
IUCN Red List status: Endangered (for wild populations). CITES Appendix II (some regions). FSC-certified plantation teak is commonly available.
Workability
Easy to work with tools but the high silica content is very abrasive to cutting edges, resulting in rapid dulling. Glues and finishes can be difficult due to natural surface oils.
Notable Features
Distinctive leather-like scent when freshly cut. Naturally high oil content makes it one of the few woods that can be used untreated outdoors for decades.
Finish Recommendations
Teak oil is traditional to maintain color; however, can be left unfinished to weather to a silver-grey. If using lacquer or polyurethane, a solvent wipe with acetone is required first to remove surface oils.
Identification Confidence
High. The golden-brown hue, large open pores, oily surface appearance, and classic cathedral grain pattern are quintessential characteristics of Tectona grandis.
